3 Description

The TPS2295x-Q1 are small, single channel load

switches with controlled turn-on. The devices contain

an 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 the switch is disabled. The enhanced

Quick Output Discharge (QOD) remains active for a

short time after power is removed from the device to

finish discharging the output.

The TPS2295x-Q1 are available in small, spacesaving

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 +125°C.
