3 Description

The TPS22997 is a single-channel load switch that

provides a configurable rise time to minimize inrush

current. The device contains an N-channel MOSFET

that can operate over an input voltage range of 0.1

V to 5.5 V and can support a maximum continuous

current of 10 A.

The switch is controlled by an enable pin (ON), which

is capable of interfacing directly with low voltage

GPIO signals (VIH = 0.8 V). The TPS22997 device

has an optional QOD pin for quick output discharge

when switch is turned off, and the fall time (tFALL)

of the output can be adjusted through an external

resistor. There is a Power Good (PG) signal on the

device that indicates when the main MOSFET is fully

turned on, which can be used to enable a downstream

load. Integrated thermal shutdown ensures protection

in high temperature environments.

The TPS22997 is available in a 1.5 × 2.0 mm,

0.5 mm pitch, 10-pin WQFN package (RYZ) and

is characterized for operation over the free-air

temperature range of –40°C to +125°C.
