The TPS22953/54 are small, single channel load switches with controlled turn on. The devices contain a N-channel MOSFET that can operate over an input voltage range of 0.7 V to 5.7 V and can support a maximum continuous current of 5 A.
The integrated adjustable undervoltage lockout (UVLO) and adjustable power good (PG) threshold provides voltage monitoring as well as robust power sequencing. The adjustable rise time control of the device greatly reduces inrush current for a wide variety of bulk load capacitances, thereby reducing or eliminating power supply droop. The switch is independently controlled by an on and off input (EN), which is capable of interfacing directly with low-voltage control signals. A 15-Ω on-chip load is integrated into the device for a quick discharge of the output when switch is disabled. The enhanced Quick Output Discharge (QOD) remains active for short time after power is removed from the device to finish discharging the output.
The TPS22953/54 are available in small, space-saving 10-SON packages 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.

The TPS22954 device is a single channel low RON load switch with an operating voltage range of 0.7 V to 5.7 V. Both package versions DSQ (0.4mm pin pitch) and DQC (0.5mm pin pitch) of the TPS22954 are available on the TPS22954EVM for evaluation. The TPS22954 integrates a voltage supervisor which (...)
The TIDA-00399 design implements a complete power delivery solution for an SSD in the M.2 form factor. The TPS22954 load switch is used to limit inrush current and eliminate the need for a separate supervisor circuit on the system input. This design is tested and includes GUI, demo, and User's (...)
