ONNCV8402ASTT1G
Overview
The NCV8402ASTT1G is a self-protected 2.0A N-Channel Low-Side MOSFET driver designed for rugged automotive and industrial switching environments. It integrates protection features such as current limiting, thermal shutdown with auto-restart, and overvoltage clamping to replace standard MOSFETs in high-reliability applications. This AEC-Q100 qualified device is capable of switching inductive, capacitive, or resistive loads while maintaining a low typical Rds(on) of 165mOhm.
Why Choose This Part
This device offers comprehensive fault protection including fixed current limiting and thermal shutdown with an automatic restart feature. It simplifies PCB design by integrating the gate drive logic and protective clamping circuitry into a compact SOT-223 package, reducing component count compared to discrete MOSFET solutions.
Applications
Key Specifications
Getting Started
To evaluate this part, design a PCB footprint for the SOT-223 package with sufficient copper area on Pin 4 (Tab) for thermal dissipation. Ensure the logic-level input signal does not exceed 14V, and verify that the load current remains within the 2.0A continuous rating for the intended ambient temperature.
