The TPS22962 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 10 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 TPS22962 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.
