Dual-channel high-side load switch for automotive power domains
The Texas Instruments TPS22968QDMGRQ1 is a dual-channel, high-side N-channel load switch designed for automotive power-distribution applications. Each of the two independent channels can handle up to 4 A continuous output, with a typical on-resistance of 29 mOhm. The load voltage range spans 0.8 V to 5.5 V, while the bias supply (Vcc/Vdd) requires 2.5 V to 5.5 V. An integrated load-discharge feature and slew-rate control help manage inrush and ensure clean rail sequencing. The part is controlled via a simple On/Off interface (enable pin per channel), with a 1:1 input-to-output ratio.
Automotive-grade qualification and lifecycle
The TPS22968QDMGRQ1 carries AEC-Q100 qualification (Grade 1, -40°C to 125°C), confirming it meets automotive reliability standards for stress, service life, and quality. It is ROHS3 compliant.
