Dual high-side switch with adjustable current limit
The TPS2561AQDRCTQ1 is a dual-channel high-side power switch from Texas Instruments, rated for automotive applications per AEC-Q100. Each of the two outputs delivers up to 2.5 A with a typical on-resistance of 44 mOhm, keeping conduction losses manageable even at full load. The 1:2 input-to-output ratio lets a single supply rail feed two independent loads — common for dual USB ports, sensor clusters, or actuator supplies in automotive body controllers.
Active lifecycle and automotive qualification
The AEC-Q100 qualification means the device has passed the full suite of automotive stress tests (high-temperature operating life, temperature cycling, ESD, latch-up). For non-automotive builds, the wide temp range still suits industrial outdoor or engine-bay environments.
