DESCRIPTION
The TPS22963/64 is a small, ultra-low R_ON load
switch with controlled turn on. The device contains a
low R_DSON N-Channel MOSFET that can operate over
an input voltage range of 1V to 5.5V and switch
currents of up to 3A. An integrated charge pump
biases the NMOS 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 GPIO 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°C to 85°C.

(1) Additional rise time options are possible. Contact factory for more information.
(2) This feature discharges the output of the switch to ground through a 273Ω resistor, preventing the output from floating (only in
TPS22964C).
