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
(rON). 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-Ω 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.
