1 Features
3 Description
The TPS22914/15 is a small, low RON, single channel
1
Integrated Single Channel Load Switch
load switch with controlled slew rate. The device
Input Voltage Range: 1.05 V to 5.5 V
contains an N-channel MOSFET that can operate
Low On-Resistance (RON)
over an input voltage range of 1.05 V to 5.5 V and
can support a maximum continuous current of 2 A.
RON = 37 mΩ (Typ) at VIN = 5 V
The switch is controlled by an on/off input, which is
RON = 38 mΩ (Typ) at VIN = 3.3 V
capable of interfacing directly with low-voltage control
RON = 43 mΩ (Typ) at VIN = 1.8 V
signals.
2-A Maximum Continuous Switch Current
The small size and low RON makes the device ideal
Low Quiescent Current
for being used in space constrained, battery powered
applications. The wide input voltage range of the
7.7 µA (typ) at VIN = 3.3 V
switch makes it a versatile solution for many different
Low Control Input Threshold Enables Use of 1.0-V
voltage rails. The controlled rise time of the device
or Higher GPIO
greatly reduces inrush current caused by large bulk
Controlled Slew Rate
load capacitances, thereby reducing or eliminating
power supply droop. The TPS22915 further reduces
tR(TPS22914B/15B) = 64 µs at VIN = 3.3 V
the total solution size by integrating a 143-
Ω pull-
tR(TPS22914C/15C) = 913 µs at VIN = 3.3 V
down resistor for quick output discharge (QOD) when
