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.
