3 Description

The TPS22965x is a single channel load switch that

provides configurable rise time to minimize inrush

current. The device contains an N-channel MOSFET

that can operate over an input voltage range of 0.8 V

to 5.7 V and can support a maximum continuous

current of 6 A. The switch is controlled by an on and

off input (ON), which is capable of interfacing directly

with low-voltage control signals. In the TPS22965, a

225-Ω on-chip load resistor is added for quick output

discharge when switch is turned off.

The TPS22965x is available in a small, space-saving

2-mm × 2-mm 8-pin SON package (DSG) 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.
