Texas Instruments TPS22990 5.5V 10A Load Switch
Texas Instruments TPS22990 5.5V 10A Load Switch is a 3.9mΩ, single-channel load switch with a controlled and adjustable turn-on and integrated PG indicator. The device contains an N-channel MOSFET that can operate over an input voltage range of 0.6V to 5.5V. It also can support a maximum continuous current of 10A. The wide input voltage range and high current capability enable the devices to be used in multiple designs and end equipment. The 3.9mΩ On-resistance minimizes the voltage drop across the load switch and power loss from the load switch. The Texas Instruments TPS22990 has an optional 218Ω On-chip resistor for quick discharge of the output when the switch is disabled to avoid any unknown state caused by floating supply to the downstream load.
