Overview
The NCV8402ASTT1G is a single-channel N-Channel power switch IC designed for low-side load driving applications. It features a 42V drain-source breakdown voltage and supports a continuous drain current of 2A. The device incorporates an on-resistance of 200 mOhms maximum, with a typical value of 165 mOhms. It operates within a junction temperature range of -40°C to +150°C and dissipates up to 1.7W of power. Packaged in a SOT-223-3 (TO-261) surface-mount format, it meets AEC-Q100 automotive qualification standards.
Feature Summary
- Integrates overvoltage, overtemperature, and fixed current limit protection with automatic restart functionality.
- Features a non-inverting input interface for direct logic control of the load.
- Designed for robust performance in harsh automotive environments with high thermal stability.
Applications
- Automotive lighting systems
- Solenoid and relay driver circuits
- Fan and pump motor control
Procurement Notes
Verify the specific suffix 'TT1G' corresponds to the required tape and reel packaging configuration. Confirm that the SOT-223-3 footprint matches the target PCB design. Ensure the application voltage does not exceed the 42V rating under all transient conditions. Check for RoHS compliance requirements if applicable to the final assembly standards.
Selection Notes
Select this component when a single low-side switch with integrated protection is required. It is suitable for loads drawing up to 2A at 42V. Consider alternative models if higher current capacity or high-side switching capability is needed. Verify that the thermal dissipation capabilities meet the system's power budget constraints.
Part Context
This part belongs to the NCV8402 series of self-protected power switches from onsemi. These devices are engineered for automotive electronics, providing reliable load management. The series includes variants with different current ratings and package options to suit diverse vehicle electrical architectures.
Replacement Considerations
NCV8402ASTT3G offers identical electrical specifications but utilizes a cut-tape packaging format instead of the standard reel configuration.
