XC6192
Series
Power saving Push Button Load switch
ETR33010-003
■GENERAL DESCRIPTION
The XC6192 series are the Push Button load switch with functions best suitable for battery operated devices.
The built-in high side switch is turned on by the Push Button (Turning off is also possible on the XC6192A type.) and turned off by
the "L" level signal into the SHDN pin from the MCU or the like.
In addition to these functions, this IC is equipped with output capacitor inrush current limiting function and short-circuit protection
function, realizing an intelligent load switch.
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)
The leak current at shutdown is so small, which is 10nA(TYP.), that this IC will contribute to reducing the discharge of the battery
and making shelf life longer of the devices after shipping as well as functioning as a main switch.
For the A type, it is possible to turn off forcibly in case of emergency by Push Button signal. This enables a freezed device to be
turned off. For the B type, turn-off is available only with SHDN pin.
The output capacitor inrush current limiting function suppresses excessive current that occurs when the switch is turned on,
preventing it from going into a brownout state.
The output short-circuit protection function detects the voltage drop due to the short circuit and turns off the power supply line by
force. The "L" signal on the SW pin by Push button makes the device recover.
The power good function is used to properly adjust the timing of turning on the DC/DC regulator or other system on the rear stage.
Please be sure to complete the preparation for shutting down safely before inputting the signal to SHDN pin from the MCU or the likes.
VOUT may not start up completely if the load current is 350uA (DC) or more at starting up due to the output capacitor inrush current limiting
function. Please design so that the started up load current is less than 350uA (DC) or the output on the rear stage is enabled by using the PG pin.

■OPERATIONAL EXPLANATION
The XC6192 series A type fixes VOUT at “H” voltage (same level as the VIN pin voltage) when “L” voltage is input the required
time into the SW pin, and shuts down VOUT (same level as GND) when “L” voltage is subsequently input the required time into
the SW pin, thereby realizing alternating ON/OFF control(*1). 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
the required time into the SW pin.
(*1)
The B type fixes VOUT at “H” voltage when “L” voltage is input 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 XC6192 series is equipped with a rush current prevention circuit and a short-circuit protection circuit.

■OPERATIONAL EXPLANATION (Continued)
[Turn-On sequence: Fig.3]
On the XC6192 series, when “L” voltage is input for the duration TOND into the SW pin with VOUT fixed at “L” voltage, the Pch
pre-driver transistor PM1 (Fig.1) turns ON and VOUT starts to rise. If the SW pin is switched from “L” voltage to “H” voltage while
VOUT is rising by PM1, VOUT will change to the shutdown state.
When the VOUT pin voltage reaches Inrush Current Limit Voltage (VRUSH: refer to Electrical Characteristics), the main driver
transistor PM2 (Fig.1) turns ON, and VOUT is fixed at “H” voltage even if the SW pin voltage changes to “H” voltage.
When the VOUT pin voltage reaches VRUSH, the Nch transistor NM1 that is connected to the PG pin (Fig.1) turns OFF and the
PG pin changes to high impedance.
These operations suppress rush current to the capacitor that is connected to the VOUT pin and allow the input power supply to
maintain stability. In addition, by connecting the PG pin to the Enable pin of the device that follows the XC6192 series,
malfunctioning of that device is prevented. (Fig.2)

■OPERATIONAL EXPLANATION (Continued)
[Inrush current limit and output short circuit protection:Fig.9 ]
The XC6192 series has a function that limits rush current and a circuit that shuts down the output when an output short-circuit
is detected.
During the time until the VOUT pin voltage reaches VRUSH during the Turn-On sequence, only PM1 turns ON, and therefore the
voltage rises through the Pre-driver On Resistor (RONP: refer to the Electrical Characteristics).
When the VOUT pin voltage reaches VRUSH or more, PM2 turns ON and rush current limiting is released.
The rush current at the instant when PM1 turns ON is calculated using the following equation.
Inrush Current = VIN / RONP (A)
In addition, during the time until the VOUT pin voltage reaches VRUSH by means of the rush current limiting function, the load
current while VOUT rises must be set to less than the value given by the equation below.
Start-up Load Current < (VIN – VRUSH (Max.)) / RONP (A)
Example: 4.2V – 4.15V / 135 Ohms = 0.359mA;
Note this very low 0.359mA is used to charge the output capacitors. If startup load current exceeds this, the output current will
pass thru PM1 only, and have a 135 ohm resistor creating a voltage drop. If it’s noticed that VOUT is significantly below VIN,
please ensure start-up load current is NOT exceeded.
If the VOUT pin voltage drops below the Short Circuit Detect Voltage (VSHORT: refer to the Electrical Characteristics) after the
Turn-On sequence, a short-circuit is detected and PM1 and PM2 are latched in the OFF state, causing VOUT to shut down. The
relation between the output current (ISHORT) and VSHORT when a short circuit occurs is given by the equation below.
ISHORT = (VIN - VSHORT) / RON (A)
The equation for the maximum output current is as follows.
IOUT (Min.) = (VIN - VSHORT (Max.)) / RON (Max.) (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 (1ms or more as a guideline) is input into the SHDN pin with VOUT
fixed at “H” voltage.
[PG pin]
NM1 and R2 (Fig.1) are connected to the PG pin.
NM1 is an Nch MOSFET and is synchronized with the GATE signal of PM2, so NM1 turns OFF when PM2 turns ON.
[VOUT pin]
PM1, PM2, and R1 (Fig.1), and R2 (Fig.1) and the CL discharge transistor NM2 (Fig.1) are connected to the output pin.
PM1 is a Pch MOSFET, and is effective in preventing rush current.
PM2 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 reference voltage and is a reset circuit that is input into 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

[VREF2 & POR2]
This circuit sets the initial state of the VOUT pin.
The circuit is set so that VOUT is in the shutdown state when the power is turned on, so there is no need to input “H” voltage into
the SHDN pin after power is supply to shut down the output.
[Inrush Current Limit]
This circuit limits rush current until the VOUT pin voltage reaches VRUSH.
[Short Circuit Protect]
This circuit outputs a shutdown signal if the VOUT pin voltage reaches VSHORT.
[Gate Slope]
After the VOUT pin voltage reaches VRUSH, this circuit gradually changes the GATE voltage of PM2 from “H” voltage to “L”
voltage.

■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)
Turn-On Delay Time characteristics and Turn-Off Delay Time characteristics are increased when using a capacitor larger
than 0.1 μF for CL connected to VOUT - GND (VSS). 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 SHDN pin.
8)
The TEST pin must be connected to GND (VSS).
9)
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.
10) The USP-8B06 is a thin surface-mount package. Therefore, distortion of the board during PCB mounting may be
transmitted to the IC chip, which may affect Turn-On Delay Time characteristics and Turn-Off Delay Time characteristics.
Sufficiently test actual operation before use.
11) 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.
