ATA6826-TUSY

Overview

The ATA6826-TUSY is a high-performance automotive smart power switch manufactured by Microchip Technology. It integrates three independent low-side outputs capable of driving inductive and resistive loads, including halogen lamps and solenoids. The device features integrated diagnostic capabilities such as over-temperature protection, over-current protection, and open-load detection. Designed for robust operation in harsh automotive environments, it supports PWM dimming for lighting applications and includes short-circuit to ground and battery protection mechanisms.

Feature Summary

• Integrates three independent low-side driver channels with comprehensive fault protection
• Supports Pulse Width Modulation (PWM) control for precise load regulation
• Provides advanced diagnostic feedback including open-load and over-temperature status

Applications

• Automotive exterior and interior lighting systems
• Solenoid and valve control modules
• Fan and pump motor drivers

Procurement Notes

Verify the specific suffix 'TUSY' against official Microchip documentation to confirm tape-and-reel packaging and temperature grade specifications. Ensure compatibility with automotive qualification standards required for your target application before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring multiple isolated low-side switches with integrated diagnostics. It is suitable for applications needing PWM dimming control and robust protection against electrical faults in automotive chassis or body electronics systems.
