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.
(*1) Please be sure to complete the preparation for shutting down safely before inputting the signal to SHDN pin from the MCU or the likes.
(*2) 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.
