USB power switch for automotive charging ports
It delivers up to 3.2 A continuous output from a 4.5 V to 6.5 V supply rail, making it a direct fit for USB charging ports in infotainment consoles, rear-seat entertainment, and telematics control units. The integrated fault protection set — current limiting, over-voltage, and undervoltage lockout (UVLO) — reduces external component count and simplifies the BOM for a dedicated charging port.
The 3.2 A current rating covers the USB dedicated charging port profile. The low-side N-Channel output configuration with a 1:1 input-to-output ratio means the switch sits between the load and ground. The differential input type allows the switch to work with USB data-line handshaking for charger detection. Fault protection is self-contained: current limiting prevents latch-up under a short, over-voltage protection clamps the output if the input rail spikes, and UVLO holds the switch off until the supply is stable.
It is ROHS3 compliant. No second-source or pin-compatible alternate is documented in the Texas Instruments portfolio for this exact automotive-grade ordering code.
