3 Description

The TPS22996 product family consists of two devices:

TPS22996 and TPS22996N. Each device is a dualchannel

load switch with controlled turnon. The device

contains two N-channel MOSFETs that can operate

over an input voltage range of 0.6 V to 5.5 V, and

can support a maximum continuous current of 4 A

per channel. Each switch is independently controlled

by an on and off input (ON1 and ON2), which can

interface directly with low-voltage control signals. The

TPS22996 is capable of thermal shutdown when the

junction temperature is above the threshold, turning

the switch off. The switch turns on again when the

junction temperature stabilizes to a safe range. The

TPS22996 also offers an optional integrated 230-Ω

on-chip load resistor for quick output discharge when

the switch is turned off.

The TPS22996 is available in a small, spacesaving

2.1-mm × 1.6-mm 8-DRL Package with

leads to enable low cost manufacturing. The device

is characterized for operation over the free-air

temperature range of –40°C to 105°C.
