DESCRIPTION
The TPS27081A IC is a high side load switch that
integrates a Power PFET and a Control NMOS in a
tiny package.
The TPS27081A is fully protected against ESD
strikes on all pins. The TPS27081A features industry-
standard ESD protection on all pins thus providing
better ESD compatibility with other on-board
components.
The TPS27081A level shifts ON/OFF logic signal to
VIN levels and thus supports as low as 1.2V CPU or
MCU logic to control higher voltage power supplies
(VIN) without requiring an external level shifter.
Switching a large value output capacitor CL through a
fast ON/OFF logic signal may result in an excessive
inrush current. To control the load inrush current
connect a resistor R2, as shown in
Figure 2
To
further limit the inrush current add an external
capacitor C1. To configure the TPS27081A to
achieve a specific slew rate refer to the Application
section.
A single external component, R1, is required in
applications that do not require inrush current control.
In such applications connect the TPS27081A pin R2
to system ground.
