NCV8461DR2G

Overview

The NCV8461DR2G is a high-side smart discrete driver from onsemi, designed for switching resistive, inductive, and capacitive loads. It operates within a supply voltage range of 5 V to 34 V and features an internal current limit of 1.2 A with a typical RDS(ON) of 350 mΩ. The device includes comprehensive protection mechanisms such as short-circuit protection, thermal shutdown with auto-restart, overvoltage protection, ground loss detection, and ESD protection. It utilizes an integrated clamp circuit for inductive switching and offers low standby current. The component is housed in an 8-pin SOIC package and meets AEC-Q100 automotive standards.

Feature Summary

CMOS (3V/5V) compatible control input for versatile interfacing
Integrated thermal shutdown with automatic restart functionality
Off-state open load detection capability
Low standby current consumption

Applications

Automotive lighting systems
Solenoid drivers
Actuator control
Industrial automation systems
Replacement for electromechanical relays

Procurement Notes

Verify the specific suffix DR2G corresponds to the SOIC-8 tape and reel packaging configuration. Confirm that the AEC-Q100 qualification aligns with target automotive reliability requirements. Ensure the operating temperature range of -40°C to 150°C meets environmental specifications. Validate compatibility with system voltage levels between 5 V and 34 V before integration.

Selection Notes

Select this component when a single-channel high-side driver with moderate current capacity is required. It is suitable for applications needing robust protection against short circuits and thermal overload. Consider its CMOS-compatible interface for direct microcontroller connection. Evaluate the trade-off between the 350 mΩ typical resistance and the 1.2 A current limit against load requirements.

Part Context

The NCV8461 belongs to onsemi's family of high-side smart discrete drivers, engineered for reliable load switching in demanding environments. It serves as a compact alternative to mechanical relays and discrete transistor circuits. The series emphasizes efficiency and durability through advanced protection features like ground loss detection and integrated clamping.
