Output Current

The built-in high side switch is turned on by the Push

Button (Turning off is also possible on the A type.) and

turned off by the "L" level signal into the SHDN pin from the

MCU or the like.

The high side switch is turned on and latched by inputting

"L" signal from the Push Button of the device to the SW pin.

It is possible to shut down (OFF) by inputting a 1-pulse

signal of "H" level from the MCU or the like to the SHDN pin.

This realizes a main switch of battery operated devices

easily. ^(*1)

■OPERATIONAL EXPLANATION

The XC6194 series type-A fixes V_OUTat “H” voltage (same level as the V_INpin voltage) when “L” voltage is input for the

required time into the SW pin, and shuts down V_OUT(same level as GND) when “L” voltage is subsequently input for the required

time into the SW pin, thereby realizing alternating ON/OFF control^(*). Two shutdown methods are available: inputting “H” voltage

into the SHDN pin, and inputting “L” voltage the required time into the SW pin.

* Alternating ON/OFF control on this IC is a system that alternates between V_OUT“H” voltage and shutdown each time “L” voltage is input for the

required time into the SW pin.

The type-B fixes V_OUTat “H” voltage when “L” voltage is input for the required time into the SW pin. After V_OUTis fixed at “H”

voltage, the signal is not accepted if “L” voltage is subsequently input into the SW pin. The shutdown method is inputting “H”

voltage into the SHDN pin.

As protective functions, the XC6194 series are equipped with the inrush current limiting soft-start circuit, the output short

protection circuit and the thermal shutdown circuit.

■OPERATIONAL EXPLANATION (Continued)

[Turn-On sequence: Fig.3]

If Voltage “Low” is input over the duration of T_ONDto the SW pin while V_OUTis fixed at Voltage “Low”, V_OUTwill begin to rise while

the output current is being suppressed by the inrush current limit soft-start function, which will gradually turns on the Pch driver

transistor PM1 (refer to Fig.1).

Even if the SW pin voltage changes to the Voltage “High” while V_OUTis rising, V_OUTwill ultimately be fixed at Voltage “High”.

When the gate voltage of the PM1 has dropped sufficiently, the NM1 connected to the PG pin will turns off, and the PG pin will

have a high-impedance.

In addition, by connecting the PG pin to the Enable pin of the device that follows the XC6194 series, malfunctioning of that device

is prevented. (Fig. 2)

■OPERATIONAL EXPLANATION (Continued)

[Thermal shutdown function: Fig.9]

The XC6194 series are equipped with thermal shutdown functions.

If a load current causes the V_OUTpin voltage to drop by roughly 50mV(TYP.) compared to the V_INpin voltage, the overheat

protection circuit will be activated and begin monitoring the IC heat generation.

If the IC temperature is equal to or greater than the Thermal Shutdown Detect Temperature (T_TSDD: refer to Electrical

Characteristics), the function will turn PM1 OFF and stop the supply of load current.

Also, if the discontinuation of the load current supply causes the IC temperature is equal to or less than the Thermal Shutdown

Release Temperature (T_TSDR: refer to Electrical Characteristics), the IC operation will automatically be restored. The inrush current

limit soft start function also operates during automatic restoration.

However, if the V_OUTpin voltage is equal to or less than the Short Circuit Detect Voltage (V_SHORT: refer to Electrical Characteristics)

before the IC temperature is equal to or less than T_TSDR, the IC will shut down.

Then, by performing turn-on sequence (refer to Fig.3: Turn-On Sequence), V_OUTis turned on again.

■OPERATIONAL EXPLANATION (Continued)

[Inrush current limit and output short circuit protection: Fig.10]

The XC6194 series are equipped with the inrush current limiting soft-start function and the function of shutting down the output

when output short circuit is detected.

After the Turn-On sequence (refer to Fig.3: Turn-On Sequence), if the V_OUTpin voltage is equal to or less than the Short Circuit

Detect Voltage (V_SHORT: refer to Electrical Characteristics) for a duration equal to or longer than the Short Circuit Detect Delay

Time (T_SHORT: refer to Electrical Characteristics), it will be identified as output short. And the PM1 is latched off-state, causes V_OUT

to shut down.

The relation between the output current (I_SHORT) and V_SHORTwhen output short occurs is given by the equation below.

I_SHORT= (V_IN- V_SHORT) / R_ON(A)

* R_{ON_min}is interlocked with V_{SHORT_max}, and R_{ON_max}is interlocked with R_{ON_min}

During the Turn-On sequence, if the V_OUTpin voltage is equal to or less than the V_SHORTvoltage, the output short-circuit protection

function will not operate.

Once the V_OUTpin voltage is greater than the V_SHORTvoltage, the output short-circuit protection function will begin to operate.

The equation for the maximum output current is as follows.

I_OUT(Min.) = (V_IN- V_{SHORT_max}) / R_{ON_min}(A)

■OPERATIONAL EXPLANATION (Continued)

[SW pin]

When “L” voltage is input into the SW pin for the duration t_ONDwith the IC in the standby state, the pin fixes V_OUTat “H” voltage.

On the A type, when V_OUTis fixed at “H” voltage, “L” voltage can be input for the duration t_OFFDto shut down V_OUT

.

[SHDN pin]

This pin shuts down V_OUTwhen one pulse of “H” voltage (100μs or more as a guideline) is input into the SHDN pin with V_OUTfixed at “H” voltage.

[PG pin]

PG pin are connected with NM1 and R2(Fig.1).

Since NM1 is the N-ch MOSFET and it is synchronized with the GATE signal of PM1, if PM1 turns ON, NM1 will turn OFF, and if PM1 turns OFF,

NM1 will turn ON.

[VOUT pin]

V_OUTpin is connected with PM1, R1 (Fig.1) and CL discharge transistor NM2 (Fig.1).

PM1 is a Pch MOSFET and functions as the main driver.

NM2 is an Nch MOSFET, and is synchronized with the GATE signal of PM1. Therefore, when PM1 turns ON, NM2 turns OFF.

[SW Circuit]

This circuit transmits the signal input into the SW pin to the internal circuitry.

[SHDN Circuit]

This circuit transmits the signal input into the SHDN pin to the internal circuitry.

[VREF & POR]

This circuit supplies the internal circuit with reference voltage as well as a reset signal to the logic circuitry.

[Type Select]

This circuit selects the product type.

[Turn-On Delay Counter]

This circuit count-controls the time until V_OUTis fixed at “H” voltage after “L” voltage is input into the SW pin.

During the time until the count is completed, the counter circuit can be returned to the initial state by inputting “H” voltage into the SW pin.

[Turn-Off Delay Counter]

This circuit only operates on the A type.

When V_OUTis fixed at “H” voltage, this circuit count-controls the time from input of “L” voltage into the SW pin until V_OUTshuts down.

During the time until the count is completed, the counter circuit can be returned to the initial state by inputting “H” voltage into the SW pin.

[UVLO]

It is Under Voltage Lock Out circuit. V_OUTwill shut down if the input voltage is less than V_UVLO

.

[IREF]

It is internal circuit reference current source.

[Soft Start (Inrush Current Limit)]

A circuit which slowly switches the PM1 gate voltage from Voltage “High” to Voltage “Low”, and limits the inrush current.

[Short Circuit Protect]

This circuit outputs a signal to shut down if the V_OUTpin voltage reaches V_SHORT

.

Also, this function will stop until V_OUTturns ON and reaches V_SHORT. Until then, only the Thermal Shutdown circuit will operate as a protection

function.

[Thermal Shutdown]

If a load current causes the V_OUTpin voltage to drop by roughly 50mV (TYP.) compared to the V_INpin voltage, this function will begin monitoring

the IC heat generation. If the IC temperature is equal to or greater than T_TSDD, it will turn off the PM1 and stop the supply of load current.

■NOTES ON USE

1) For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be

exceeded.

2) Please use this IC within the specified operating ranges.

3) In some cases, power supply noise may cause malfunctioning of the internal counter circuit. Sufficiently reinforce the V_IN,

V_OUT, and GND lines, and connect 0.1μF or higher capacitors near the IC between V_INand GND (V_SS), and between V_OUT

and GND (V_SS).

4) When using the capacitor larger than 100μF for C_L, it is possible that Inrush Current becomes large. Please sufficiently test

actual operation before use.

5) When “L” level is input into the SW pin, Operation Current flows. Sufficiently test actual operation before designing peripheral

circuits.

6) The SW pin and SHDN pin are connected to the gate of a CMOS inverter. If a voltage lower than the V_INpin voltage or

a voltage higher than the V_SSpin voltage is input into each pin, the flow-through current of the CMOS inverter may appear as

supply current.

7) If an intermediate voltage between “L” voltage and “H” voltage is input into the SW pin or SHDN pin,

starting and stopping of the IC may become unstable. Sufficiently test peripheral components and other

parts to ensure that an intermediate voltage between “L” voltage and “H” voltage is not continuously input

for an excessive time into the SW pin and the SHDN pin.

8) Since electromagnetic wave may cause unexpected malfunction, please reinforce the shielding of the equipment and connect

a filter to each terminal as necessary and fully check with actual equipment before using.

9) The TEST pin must be connected to GND (V_SS).

10) When transiently varying the input voltage, please make sure to set the slew rate under 1V/us.

11) When using for an application other than a push-button application, please design the timing to include

deviations and test sufficiently with the actual device before use.

12) Torex places an importance on improving our products and their reliability.

We request that users incorporate fail-safe designs and post-aging protection treatment when using

Torex products in their systems.
