Overview

The TPS22963/64 is a small, ultra-low Rou load switch with controlled turn on. The device contains a low RpsoN N-Channel MOSFET that can operate over an input voltage range of 1 V to 5.5 V and switch currents of up to 3 A. An integrated charge pump biases the MOS switch in order to achieve a low switch ON-Resistance. The switch is controlled by an on/off input (ON), which is capable of interfacing directly with low-voltage GPlO control signals. The rise time of the TPS22963/64 device is internally controlled in order to avoid inrush current. The TPS22963/64 provides reverse current protection. When the power switch is disabled, the device will not allow the flow of current towards the input side of the switch. The reverse current protection feature is active only when the device is disabled so as to allow for intentional reverse current (when the switch is enabled) for some applications. The TPS22963/64 is available in a small, space- saving 6-pin WCSP package and is characterized for operation over the free air temperature range of -40℃ to 85℃.
