3 Description
The TPS22953/54 are small, single channel load
switches with controlled turn on. The devices contain
a N-channel MOSFET that can operate over an input
voltage range of 0.7 V to 5.7 V and can support a
maximum continuous current of 5 A.
The integrated adjustable undervoltage lockout
(UVLO) and adjustable power good (PG) threshold
provides voltage monitoring as well as robust power
sequencing. The adjustable rise time control of the
device greatly reduces inrush current for a wide
variety of bulk load capacitances, thereby reducing or
eliminating power supply droop. The switch is
independently controlled by an on and off input (EN),
which is capable of interfacing directly with low-
voltage control signals. A 15-Ω on-chip load is
integrated into the device for a quick discharge of the
output when switch is disabled. The enhanced Quick
Output Discharge (QOD) remains active for short time
after power is removed from the device to finish
discharging the output.
The TPS22953/54 are available in small, space-
saving 10-SON packages with integrated thermal pad
allowing for high power dissipation. The device is
characterized for operation over the free-air
temperature range of –40°C to +105°C.
