Description

The TPS22990 product family consists of two devices: TPS22990 andTPS22990N. Each device is a 3.9-m?, single-channel load switch with a controlled and adjustableturn on and integrated PG indicator.

The devices contain an N-channel MOSFET that can operate over an input voltage range of0.6 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 usedacross multiple designs and end equipments. 3.9-m? On-resistance minimizes the voltage drop acrossthe load switch and power loss from the load switch.

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

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

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.
