open-in-new Find other Load switches

Description

The TPS22975 product family consists of two devices: TPS22975 and TPS22975N. Each device is a single-channel load switch that provides a configurable rise time to minimize inrush current. The device contains an N-channel MOSFET that can operate over an input voltage range of 0.6 V to 5.7 V and can support a maximum continuous current of 6 A. The switch is controlled by an on and off input (ON), which is capable of interfacing directly with low-voltage control signals. TPS22975 has an optional 230-Ω on-chip load resistor for quick output discharge when switch is turned off.

The TPS22975 is available in a small, space-saving 2-mm × 2-mm 8-pin SON package (DSG) with integrated thermal pad allowing for high power dissipation. The device is characterized for operation over the free-air temperature range of –40°C to +105°C.
