Features, Applications

The is a small, space-saving load switch with controlled Turn-ON to reduce inrush current. The device contains an N-channel MOSFET that can operate over an input voltage range 3.6 V and pulsed switch currents A. An integrated charge pump biases the NMOS switch in order to achieve a minimum switch ON resistance (RON). The switch is controlled an on and off input (ON), which is capable of interfacing directly with lowvoltage control signals. The TPS22970 is capable of thermal shutdown when the junction temperature is above the threshold, turning the switch off. The switch turns on again when the junction temperature stabilizes to a safe range. The TPS22970 has a 150- 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 TPS22970 has an internally controlled rise time in order to reduce inrush current. The TPS22970 is available in an ultra-small, space saving 8-pin WCSP package and is characterized for operation over the free-air temperature range to +105C. Device Information(1)
