3 Description

The TPS22959 is a small, ultra-low RON, single

channel load switch with controlled turn on. The device contains an N-channel MOSFET that can

operate over an input voltage range of 0.8 V to 5.5 V

and supports a maximum continuous current of 15 A.

The combination of ultra-low RON and high current

capability of the device makes it ideal for driving

processor rails with very tight voltage dropout tolerances. The controlled rise time of the device

greatly reduces inrush current caused by large bulk

load capacitances, thereby reducing or eliminating

voltage droop on the power supply. The switch can

be independently controlled via the ON pin, which is

capable of interfacing directly with low-voltage control

signals originating from microcontrollers or low

voltage discrete logic. The device further reduces the

total solution size by integrating a 224-Ω pull-down

resistor for quick output discharge (QOD) when the

switch is turned off.

The TPS22959 is available in a small 3.00 mm x 3.00 mm WSON-8 package (DNY). The DNY package

integrates a thermal pad which allows for high power

dissipation in high current and high temperature

applications. The device is characterized for operation over the free-air temperature range of

–40°C to 105°C.
