ETR33010-001 Power saving Push Button Load switch в– GENERAL DESCRIPTION
The XC6192 series are power saving push button load switch ICs that shut down (shut OFF) the power line after shipping testing
of battery-equipped devices. This enables a significant saving of power consumption during prolonged storage.
The power line can be forcefully shut down (shut OFF) by inputting one вЂњHвЂќ level pulse into the SHDN pin.
The A type is equipped with an alternating ON/OFF control (*1) that turns the power line ON/OFF each time вЂњLвЂќ signal is input into
the SW pin for a set period of time, and is ideal for ON/OFF power switch applications and Ideal for forced shutdown in emergency.
The B type fixes the power line in the power ON state when an вЂњLвЂќ signal is input into the SW pin for a set period of time, and once
the power line is in the power ON state, shutdown by the SW pin is not possible. This type is ideal for shipping mode applications
where the power line is shut down (shut OFF) only for shipping using shutdown by the SHDN pin.
The XC6192 series enables input of an existing switch signal that is shared with other devices into the SW pin, and the small,
surface-mount package contributes to space saving.
This IC is equipped with a SHDN pin that forcefully shuts down (shuts OFF) the power line, a PG pin (Nch open drain) that
outputs a flag signal when it detects that the output voltage has risen, and as protective functions, an output short circuit protection
function (fixes the power line at OFF when a voltage drop caused by a short circuit is detected), a rush current prevention function
(startup through a resistance of 105в„¦ (Typ.) between VIN-VOUT until VOUT reaches a set voltage), and an output capacitor discharge
The supply current during shutdown is a very small 0.01ОјA (Typ.), which contributes to energy saving during prolonged storage.
The вЂњAlternating ON/OFF control on this IC is a system that alternates between VOUT вЂњHвЂќ voltage and shutdown each time вЂњLвЂќ voltage is input the required time into the
