■GENERAL DESCRIPTION
:
:
:
:
1.8V ~ 6.0V
The XC6193 series are the Push Button load switch with
functions best suitable for battery operated devices.
0.001μA (TYP.) / Turn-Off state
0.13μA (TYP.) / Turn-On state
Only Internal FET - 1000mA (VIN=2.0V)
Quiescent Current
Output Current
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.
External FET
- Depend on FET
Turn-On Delay Time
Turn-Off Method
:
:
0.2s, 1.0s, 3.0s or 5.0s
Type A
Type B
・By inputting “H” voltage to
the SHDN pin.
・By inputting “L” voltage
during the TOFFD to the SW pin.
・By inputting “H” voltage to
the SHDN pin.
This realizes a main switch of battery operated devices
(*1)
easily.
(The XC6193 series are possible to control not
only the built-in high side switch but also the external Pch
MOSFET.)
Turn-Off Delay Time
Added function
:
:
3s, 5s, 10s or 15s
External MOSFET Control function
(The GATE pin)
The leak current at shutdown is so small, which is
1nA(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.
Shutdown function (the SHDN pin)
Output capacitor inrush current limit soft-start
Output capacitor discharge
Output short circuit protection
Thermal shutdown
Protective function
:
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.
Operating Ambient Temperature
:
:
-40℃ ~ 85℃
Package
USP-8B06 (2.0 x 2.0 x h0.33mm)
In addition to the built-in high side switch, the XC6193
series has the GATE pin for driving an external Pch
MOSFET.
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.

(*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.
