TPS22968-Q1 (ACTIVE)

5.5V, 27mΩ 2-Ch Automotive High-Side Load Switch with Adj Rise Time & Quick Output Discharge

 

Description

The TPS22968x-Q1 is a small, dual-channel load switch with configurable rise time. The device contains two N-channel MOSFETs that can operate over an input voltage range of 0.8 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/off input (ON1 and ON2), which is capable of interfacing directly with low-voltage control signals. The TPS22968-Q1 includes a 270 Ω on-chip resistor for quick output discharge when the switch is turned off.

The TPS22968x-Q1 is available in a small, space-saving package (DMG) with wettable flanks and an integrated thermal pad. The wettable flanks allow for visual solder inspection. The device is characterized for operation over the free-air temperature range of –40 to +125°C.
