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 VOUT at “H” voltage (same level as the VIN pin voltage) when “L” voltage is input for the
required time into the SW pin, and shuts down VOUT(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 VOUT “H” voltage and shutdown each time “L” voltage is input for the
required time into the SW pin.
The type-B fixes VOUT at “H” voltage when “L” voltage is input for the required time into the SW pin. After VOUT is 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 TOND to the SW pin while VOUT is fixed at Voltage “Low”, VOUT will 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 VOUT is rising, VOUT will 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)

In the XC6194 series, when one pulse of “H” voltage (at least 100μs as a guideline) is input into the SHDN pin with VOUT fixed at

■OPERATIONAL EXPLANATION (Continued)
[Thermal shutdown function: Fig.9]
The XC6194 series are equipped with thermal shutdown functions.
If a load current causes the VOUT pin voltage to drop by roughly 50mV(TYP.) compared to the VIN pin 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 (TTSDD: 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 (TTSDR: 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 VOUT pin voltage is equal to or less than the Short Circuit Detect Voltage (VSHORT: refer to Electrical Characteristics)
before the IC temperature is equal to or less than TTSDR, the IC will shut down.
Then, by performing turn-on sequence (refer to Fig.3: Turn-On Sequence), VOUT is 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 VOUT pin voltage is equal to or less than the Short Circuit
Detect Voltage (VSHORT: refer to Electrical Characteristics) for a duration equal to or longer than the Short Circuit Detect Delay
Time (TSHORT: refer to Electrical Characteristics), it will be identified as output short. And the PM1 is latched off-state, causes VOUT
to shut down.
The relation between the output current (ISHORT) and VSHORT when output short occurs is given by the equation below.
ISHORT = (VIN - VSHORT) / RON (A)
* RON_min is interlocked with VSHORT_max, and RON_max is interlocked with RON_min
During the Turn-On sequence, if the VOUT pin voltage is equal to or less than the VSHORT voltage, the output short-circuit protection
function will not operate.
Once the VOUT pin voltage is greater than the VSHORT voltage, the output short-circuit protection function will begin to operate.
The equation for the maximum output current is as follows.
IOUT (Min.) = (VIN - VSHORT_max) / RON_min (A)

■OPERATIONAL EXPLANATION (Continued)
[SW pin]
When “L” voltage is input into the SW pin for the duration tOND with the IC in the standby state, the pin fixes VOUT at “H” voltage.
On the A type, when VOUT is fixed at “H” voltage, “L” voltage can be input for the duration tOFFD to shut down VOUT
.
[SHDN pin]
This pin shuts down VOUT when one pulse of “H” voltage (100μs or more as a guideline) is input into the SHDN pin with VOUT fixed 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]
VOUT pin 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 VOUT is 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 VOUT is fixed at “H” voltage, this circuit count-controls the time from input of “L” voltage into the SW pin until VOUT shuts 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. VOUT will shut down if the input voltage is less than VUVLO
.
[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 VOUT pin voltage reaches VSHORT
.
Also, this function will stop until VOUT turns ON and reaches VSHORT. Until then, only the Thermal Shutdown circuit will operate as a protection
function.
[Thermal Shutdown]
If a load current causes the VOUT pin voltage to drop by roughly 50mV (TYP.) compared to the VIN pin voltage, this function will begin monitoring
the IC heat generation. If the IC temperature is equal to or greater than TTSDD, 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 VIN,
VOUT, and GND lines, and connect 0.1μF or higher capacitors near the IC between VIN and GND (VSS), and between VOUT
and GND (VSS).
4) When using the capacitor larger than 100μF for CL, 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 VIN pin voltage or
a voltage higher than the VSS pin 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 (VSS).
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.
