3 Description
The TPS22914/15 is a small, low RON, single channel
load switch with controlled slew rate. The device
contains an N-channel MOSFET that can operate
over an input voltage range of 1.05 V to 5.5 V and
can support a maximum continuous current of 2 A.
The switch is controlled by an on and off input, which
is capable of interfacing directly with low-voltage
control signals.
The small size and low RON makes the device ideal
for being used in space constrained, battery powered
applications. The wide input voltage range of the
switch makes it a versatile solution for many different
voltage rails. The controlled rise time of the device
greatly reduces inrush current caused by large bulk
load capacitances, thereby reducing or eliminating
power supply droop. The TPS22915 further reduces
the total solution size by integrating a 143-Ω pull-
down resistor for quick output discharge (QOD) when
the switch is turned off.
The TPS22914/15 is available in a small, space-
saving 0.78 mm x 0.78 mm, 0.4-mm pitch, 0.5-mm
height 4-pin Wafer-Chip-Scale (WCSP) package
(YFP). The device is characterized for operation over
the free-air temperature range of –40°C to +105°C.
