R5480x Series
1-Cell Li-Ion Battery Protection IC
OUTLINE
NO.EA-308-161215
The R5480x is a protection IC for over-charge of rechargeable Lithium-ion (Li+)/Lithium polymer battery. The
R5480 can detect over-charge, over-discharge, excess-discharge current, and excess-charge current of one-
cell Lithium-ion (Li+)/Lithium polymer battery. The external resistor of RSENSE pin allows a high-accuracy
detection for excess current. The supply current after detecting over-discharge is suppressed as much as
possible by stopping the internal circuit.

Output Delay Time Shortening Function
At COUT is “H”, if V- level is set at −2.0 V, the Output Delay time of detect the over-charge and over-discharge
can be reduced (Delay Time for over-charge becomes about 1/100 of normal state).

RECOMMENDED OPERATING CONDITIONS
All of electronic equipment should be designed that the mounted semiconductor devices operate within the
recommended operating conditions. The semiconductor devices cannot operate normally over the recommended
operating conditions, even if when they are used over such conditions by momentary electronic noise or surge. And
the semiconductor devices may receive serious damage when they continue to operate over the recommended
operating conditions.

R1 and C1 stabilize a supply voltage to the R5480. A recommended R1 value is equal or less than 1kΩ.
A large value of R1 makes detection voltage shift higher because of the conduction current flowed in the
R5480. Further, to stabilize the operation of R5480, use the C1 with the value of 0.01µF or more.
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 R5480, battery pack. While small value of R1 and R2 may cause over
power dissipation rating of the R5480, therefore a total of “R1+R2” should be 1kΩ or more. Besides, if a
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.
R3 is a resistor for sensing an excess current. If the resistance value is too large, power loss becomes
also large. By the excess current, if the R3 is not appropriate, the power loss may be beyond the power
dissipation of R3. Choose an appropriate R3 according to the cell specification.
The typical application circuit diagram is just an example. This circuit performance largely depends on the
PCB layout and external components. In the actual application, fully evaluation is necessary.

Over-voltage and the over current beyond the absolute maximum rating should not be forced to the
protection IC and external components. Although the short protection circuit is built in the IC, if the positive
terminal and the negative terminal of the battery pack are short, during the delay time of short limit detector,
large current flows through the FET. Select an appropriate FET with large enough current capacity to
prevent the IC from burning damage.
We are making our continuous effort to improve the quality and reliability of our products, but
semiconductor products are likely to fail with certain probability. In order to prevent any injury to humans
or damages to property resulting from such failure, users should be careful enough to incorporate safe
measures in design, such as redundancy, fire-containment, and fail-safe feature. We do not assume any
liability or responsibility for any loss or damage arising from misuse or inappropriate use of the products.
If the positive terminal and the negative terminal of the battery pack are short, even though the short
protection circuit is built in the IC, during the delay time until detecting the short circuit, a large current
may flow through the FET. Select an FET with large enough current capacity in order to endure the large
current during the delay time.

Sense Resistance and On-resistance of the MOSFET Selection Guideline
Short mode is detected by the current base or the relation between VDD at short and total on-resistance of
external MOSFETs for COUT and DOUT.
If short must be detected by the current base determined by VSHORT and R3, the next formula must be true,
otherwise, the short current limit becomes (VDD - 0.9)/(R3 + RSS (on))
VDD − 0.9
VSHORT
R3
≥
R3 + RSS (on)
VSHORT = 0.5 V (R5480xxxxCG), 0.18 V (R5480xxxxCL), 0.14 V (R5480xxxxUM)
R3 = External current sense resistance (Ω)
RSS (on) = external MOSFETs’ total on-resistance (Ω)
VDD = VDD level at short mode. If VDD goes down by the short current, the lowest level is VDD.
Ex. 1
As the RSENSE, in case that the 10 mΩ is selected as R3 and if the VDD becomes 3.0 V, to detect short at 50 A
with VSHORT = 0.5 V, the RSS (on) must be 32 mΩ or lower.
Ex. 2
As the RSENSE, in case the 20 mΩ is selected as R3 and if the VDD becomes 3.0 V, to detect short at 25 A with
VSHORT = 0.5 V, the RSS (on) must be 64 mΩ or lower.
If the RSS (on) value is higher than the value calculated by this formula, the short current limit will be less than
the desired value.
