R5403x/R5405x SERIES

Li-ION/POLYMER 1CELL PROTECTOR

NO. EA-215-120911

OUTLINE

The R5403x Series and the R5405x Series are high voltage CMOS-based protection ICs for

over-charge/discharge of rechargeable one-cell Lithium-ion/Lithium polymer excess load current, further include

a short circuit protector for preventing large external short circuit current and excess charge/discharge-current.

Each of these ICs is composed of four voltage detectors, reference units, a delay circuit, a short circuit

protector, an oscillator, a counter, and logic circuits.

The output of Over-charge detector or Excess charge-current detector switches to "L" level after internally

fixed delay time, when discharged voltage crosses the detector threshold from a low value to a high value.

They have two types to release Over-charge detector. The one is called "Latch type". The output of C^OUT

switches to "H" when a kind of load is connected to V^DDafter a charger is disconnected from the battery pack,

and the cell voltage becomes lower than over-charge detector threshold.

The other is called "Auto Release type". The output of C^OUTswitches to "H", when the cell voltage is lower

than over-charge detector threshold, or by disconnecting a charger.

The output of Over-discharge detector or Excess discharge-current detector switches to "L" level after

internally fixed delay time, when discharged voltage crosses the detector threshold from a high value to a value

lower than V^DET2.

They have two types to release Over-discharge detector.

The one is called "Latch type". The output of D^OUTswitches to "H" by connecting a charger to the battery pack

when the battery supply voltage becomes higher than the over-discharge detector threshold.

The other is called "Auto Release type", in case that the charger is not connected, when the cell voltage

becomes equal released voltage from over-discharge detector is released. In case that a charger is connected,

and when the cell voltage becomes higher than the over-discharge detector threshold, or becomes released

voltage from over-discharge without connecting a charger, the over-discharge detector is released.

Even if the battery is discharged to 0V, charge current is normally acceptable. However, KF version and KG

version are 0V batteries unacceptable types.

An excess discharge-current and short circuit state can be sensed and cut off through the built in excess

current detector with D^OUTbeing enabled to low level. Once after detecting excess discharge-current or short

circuit is released and D^OUTlevel switches to high by detaching a battery pack from a load system.

After detecting over-discharge, supply current will be kept extremely low by halting internal circuits' operation.

When the output of C^OUTis "H", if V- pin level is set at VSS−2V or lower, the delay time of detector can be

shortened. Especially, the delay time of over-charge detector can be reduced into approximately 1/60. Therefore,

testing time of protector circuit board can be reduced. Output type of C^OUTand DOUT are CMOS.

The R5403x Series have SOT-23-5 and DFN(PLP)1820-6.

The R5405x Series have SOT-23-6 and DFN(PLP)1616-6 and DFN1814-6.

OPERATION

• VD1 / Over-Charge Detector

The VD1 monitors VDD pin voltage while charge the battery pack. When the VDD voltage crosses over-charge

detector threshold V^DET1from a low value to a value higher than the VDET1, the VD1 can detect over-charge and

an external charge control Nch MOSFET turn off with C^OUTpin being at "L" level.

In terms of C, G version (Latch type), to reset the VD1 making the C^OUTpin level to "H" again after detecting

over-charge, in such conditions that a time when the V^DDvoltage is down to a level lower than over-charge

voltage, by disconnecting a charger from the battery pack. Output voltage of C^OUTpin becomes "H", and it makes

an external Nch MOSFET turn on, and charge cycle is available.

Depending on the external characteristics of external components such as FETs, just by disconnecting a

charger, over-charge state may not be released. In such a case, by connecting some load, the over-charge state

is released.) In other words, once over-charge is detected, even if the supply voltage becomes low enough, if a

charger is continuously connected to the battery pack, recharge is not possible. Therefore this over-charge

detector has no hysteresis. To judge whether or not load is connected, the built-in excess-discharge current

detector is used. In other words, by connecting some load, V- pin voltage becomes equal or more than

excess-discharge current detector threshold, and reset the over-charge detecting state.

In terms of D, E, F version (Auto Release type), after detecting over-charge, if V^DDpin voltage is equal or

lower than the released voltage from over-charge, even if a charger is connected, over-charge detector is

released. Further, in case that V^DDpin level is lower than the over-charge detector threshold, if a charger is

removed, over-charge detector is also released. Depending on the characteristics of external components such

as FETs, just by disconnecting a charger, over-charge detector may not be released, and in this case, by

connecting some load, the over-charge state is released.

After detecting over-charge with the V^DDvoltage of higher than VDET1, connecting system load to the battery

pack makes load current allowable through parasitic diode of external charge control FET.

The C^OUTlevel would be "H" when the VDD level is down to a level below the VDET1 by continuous drawing of

load current.

Internal fixed output delay times for over-charge detection and release from over-charge exist. Even when the

V^DDpin level becomes equal or higher level than VDET1 if the VDD voltage would be back to a level lower than the

V^DET1within a time period of the output delay time, VD1 would not output a signal for turning off the charge

control FET. Besides, after detecting over-charge, while the V^DDis lower than over-charge detector, even if a

charger is removed and a load is connected, if the voltage is recovered within output delay time of release from

over-charge, over-charge state is not released.

A level shifter incorporated in a buffer driver for the C^OUTpin makes the "L" level of COUT pin to the V- pin

voltage and the "H" level of C^OUTpin is set to VDD voltage with CMOS buffer.

• VD2 / Over-Discharge Detector

The VD2 is monitoring a VDD pin voltage. When the VDD voltage crosses the over-discharge detector threshold

V^DET2from a high value to a value lower than the VDET2, the VD2 can detect an over-discharge and the external

discharge control Nch MOSFET turns off with the D^OUTpin being at "L" level.

In terms of C, E, G version(Latch type), to reset the VD2 with the D^OUTpin level being "H" again after detecting

over discharge, it is necessary to connect a charger to the battery pack. When the V^DDvoltage stays under

over-discharge detector threshold V^DET2, charge-current can flow through parasitic diode of an external

discharge control MOSFET, then after the V^DDvoltage comes up to a value larger than VDET2, then, DOUT

becomes "H" and discharging process would be able to advance through ON state MOSFET for discharge

control.

＊R5403K (DFN(PLP)1820-6) is the discontinued product as of March in 2020.

R5403x / R5405x

Connecting a charger to the battery pack makes the DOUT level being "H" instantaneously when the VDD

voltage is higher than V^DET2.

In terms of D, F version (Auto Release type), released operation by connecting a charger is same as the other

latch type. However, without a charger, if V^DDpin voltage is equal or more than the released voltage from

over-discharge, D^OUTpin becomes "H" immediately.

When a cell voltage equals to zero, C, D, E version (acceptable type): if the voltage of a charger is equal or

more than 0V-charge minimum voltage limit (Vst), COUT pin becomes "H" and a system is allowable to charge.

F, G version (unacceptable type): if V^DDvoltage is less than charger inhibit maximum voltage (Vnochg), even if

a charger is connected, C^OUTlevel will be fixed at "L", and charge current will be cut off.

An output delay time for over-discharge detection is fixed internally. When the V^DDlevel is down to a equal or

lower level than V^DET2if the VDD voltage would be back to a level higher than the VDET2 within a time period of the

output delay time, VD2 would not output a signal for turning off the discharge control FET. Output delay time for

release from over-discharge is also set.

After detecting over-discharge by VD2, C, E, G version (Latch type): supply current would be reduced and be

into standby by halting unnecessary circuits and consumption current of IC itself is made as small as possible.

(Max. 0.1μA at V^DD=2.0V)

D, F version (Auto Release type): supply current would be reduced and be into standby by halting circuits

except the over-discharge released by voltage function. (Max. 2.0μA at V^DD=2.0V)

The output type of D^OUTpin is CMOS having "H" level of VDD and "L" level of VSS.

• VD3 /Excess discharge-current Detector, Short Circuit Protector

Both of the excess current detector and short circuit protection can work when the both of control FETs are in

"ON" state.

When the V- pin voltage is up to a value between the short protection voltage (Vshort) /VDD and excess

discharge-current threshold V^DET3, VD3 operates and further soaring of V- pin voltage higher than Vshort (Typ.

0.8V) makes the short circuit protector enabled. This leads the external discharge control Nch MOSFET turns off

with the D^OUTpin being at "L" level. An output delay time for the excess discharge-current detector is internally

fixed. A quick recovery of V- pin level from a value between Vshort and VDET3 within the delay time keeps the

discharge control FET staying "H" state. Output delay time for Release from excess discharge-current detection

is also set.

When the short circuit protector is enabled, the D^OUTwould be "L" and the delay time (Typ. 1.2ms) is also set.

The V- pin has a built-in pull-down resistor (Typ. 50kΩ) to the V^SSpin, that is, the resistance to release from

excess-discharge current.

After an excess discharge-current or short circuit protection is detected, removing a cause of excess

discharge-current or external short circuit makes an external discharge control FET to an "ON" state

automatically with the V- pin level being down to the V^SSlevel through built-in pulled down resistor. The reset

resistor of excess discharge-current is off at normal state. Only when detecting excess discharge-current or

short circuit, the resistor is on.

Output delay time of excess discharge-current is set shorter than the delay time for over-discharge detector.

Therefore, if V^DDvoltage would be lower than VDET2 at the same time as the excess discharge-current is detected,

the R5403x /R5405x are at excess discharge-current detection mode. By disconnecting a load, VD3 is

automatically released from excess discharge-current.

• VD4 /Excess charge-current detector

When the battery pack is chargeable and discharge is also possible, VD4 senses V- pin voltage. For example,

in case that a battery pack is charged by an inappropriate charger, an excess current flows, then the voltage of

V- pin becomes equal or less than excess charge-current detector threshold. Then, the output of C^OUTbecomes

＊R5403K (DFN(PLP)1820-6) is the discontinued product as of March in 2020.

R5403x/R5405x

"L", and prevents from flowing excess current in the circuit by turning off the external Nch MOSFET.

Output delay of excess charge current is internally fixed. Even the voltage level of V- pin becomes equal or

lower than the excess charge-current detector threshold, the voltage is higher than the VD4 threshold within the

delay time, the excess charge current is not detected. Output delay for the release from excess charge current

(Typ. 1.2ms) is also set.

VD4 can be released with disconnecting a charger and connecting a load.

• DS (Delay Shorten) function

Output delay time of over-charge, over-discharge, and release from those detecting modes can be shorter

than those setting value by forcing equal or less than the delay shortening mode voltage (Typ. −2.0V) to V- pin.

APPLICATION HINTS

R1 and C1 will stabilize a supply voltage to the R5403x /R5405x. A recommended R1 value is less than 1kΩ.

A larger value of R1 leads higher detection voltage, makes some errors because of some conduction current

may flow in the R5403x /R5405x. To stabilize the operation, the value of C1 should be equal or more than

0.01μF.

R1 and R2 can operate also as parts for current limit circuit against reverse charge or applying a charger with

excess charging voltage to the R5403x /R5405x, battery pack. Small value of R1 and R2 may cause over-power

consumption rating of power dissipation of the R5403x /R5405x. Thus, the total value of R1+R2 should be equal

or more than 1kΩ.

On the other hand, if large value of R2 is set, release from over-discharge by connecting a charger might not

be possible. Recommended R2 value is equal or less than 10kΩ.

The application circuit's performance is largely dependable on the actual PCB layout, therefore, fully

evaluation and selection of the appropriate external components are necessary.

Large voltage or large current, which may exceed the absolute maximum ratings of the protection IC or the

external components should not be forced on them.
