Texas Instruments TPS22920YZPT

Description
The TPS22920x is a small, space-saving load switch with controlled turn on to reduce inrush current. The device contains a N-channel MOSFET that can operate over an input voltage range of 0.75 V to 3.6 V and switch currents up to 4 A. An integrated charge pump biases the NMOS switch in order to achieve a minimum switch ON resistance (row). The switch is controlled by an on/off input (ON), which is capable of interfacing directly with low-voltage control signals. The TPS22920x has a 1250-Q on-chip resistor for quick output discharge when the switch is turned off which insures that the output is not left floating. The TPS22920x has an internally controlled rise time in order to reduce inrush current. The TPS22920x is available in an ultra-small, space-saving 8-pin CSP package and is characterized for operation over the free-air temperature range of -40°C to 85°C.
