The XC6193 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 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) (The XC6193 series are possible to control not
only the built-in high side switch but also the external Pch
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
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.
In addition to the built-in high side switch, the XC6193
series has the GATE pin for driving an external Pch
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
(*1) Please be sure to complete the preparation for shutting down
safely before inputting the signal to SHDN pin from the MCU or the
