The TPS22990 product family consists of two devices: TPS22990 and TPS22990N. Each device is a 3.9-mΩ, single-channel load switch with a controlled and adjustable turn on and integrated PG indicator.

The devices contain an N-channel MOSFET that can operate over an input voltage range of 0.6 V to 5.5 V and can support a maximum continuous current of
10 A. The wide input voltage range and high current capability enable the devices to be used across multiple designs and end equipments. 3.9-mΩ On-resistance minimizes the voltage drop across the load switch and power loss from the load switch.

The controlled rise time for the device greatly reduces inrush current caused by large bulk load capacitances, thereby reducing or eliminating power supply droop. The adjustable slew rate through CT provides the design flexibility to trade off inrush current and power up timing requirements. Integrated PG indicator notifies the system about the status of the load switch to facilitate seamless power sequencing.

The TPS22990 has an optional 218-Ω On-chip resistor for quick discharge of the output when switch is disabled to avoid any unknown state caused by floating supply to the downstream load.

The TPS22990 is available in a small, space-saving
3-mm × 2-mm 10-SON package 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.
