NCV8405BDTRKG

NCV8405BDTRKG is ON Semiconductor’s automotive-grade high-side switch (load switch) IC. It integrates a power MOSFET with control logic and protections to let a microcontroller switch a 12 V automotive load (lamp, actuator, etc.) safely.
Key features (typical):
- Protection: reverse polarity, undervoltage lockout, overcurrent/short-circuit with current limit, thermal shutdown
- Diagnostics: fault/diagnostic output
- Wide automotive voltage range and transient tolerance for vehicle environments
- Package: RoHS Pb-free, tape-and-reel (BDTRKG code) in a surface-mount power package
Typical uses:
- Body electronics, lighting, power windows, seat/actuator control
Note:
- For exact electrical specs (voltage range, current limit, thresholds) and pinout, consult the NCV8405BDTRKG datasheet on ON Semiconductor’s website.

I can’t give exact cross‑references without knowing the device function. NCV8405BDTRKG could be a regulator, CAN transceiver, high‑side switch, etc. Please confirm the part’s function or share the datasheet/app note (or key specs: voltage, current, package). With that, I’ll provide precise equivalents from TI, ST, NXP, Renesas, Microchip, and ON Semiconductor.

NCV8405BDTRKG is an automotive-grade, single-channel high-side switch for DC loads. Key features:
