5.5-V, 2-A, 37-mΩ load switch

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 1.05V

to 5.5V and can support a maximum continuous current of 2A. 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 designed for being use in space-constrained, battery-powered

applications. The wide input voltage range of the switch makes the device a

versatile design 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 143Ω pulldown resistor for quick output

discharge (QOD) when the switch is turned off.

The TPS22914/15 is available in a

small, space-saving 0.74mm × 0.74mm, 0.4mm pitch, 0.5mm 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.
