ATA6824C-MFHW-1

Overview

The ATA6824C-MFHW-1 is a System Basis Chip (SBC) designed for automotive applications, integrating a gate driver and power management functions. It features a dual half-bridge output capable of driving up to 3A per channel, suitable for controlling high-side and low-side loads such as lamps, relays, or motors. The device includes an integrated voltage regulator providing stable supply voltages for internal logic and external peripherals. Key protection mechanisms include over-current protection, thermal shutdown, and open-load detection to ensure robust operation in harsh automotive environments.

Feature Summary

• Integrates dual half-bridge gate drivers with high current capability for direct load control
• Includes integrated linear voltage regulators for system power distribution
• Provides comprehensive diagnostic features including over-current, thermal, and open-load detection

Applications

• Automotive lighting systems including headlamps and interior illumination
• Control of automotive relays and solenoids
• Low-power motor drive applications in vehicle body electronics

Procurement Notes

Verify the specific suffix MFHW-1 against official Microchip documentation to confirm package type, temperature range, and tape-and-reel specifications. Ensure compatibility with target automotive standards and validate pinout alignment during PCB layout. Cross-reference with latest datasheet revisions to confirm any changes in electrical characteristics or recommended operating conditions prior to final design approval.

Selection Notes

Select this component when a combined solution for power regulation and high-current switching is required in space-constrained automotive designs. It is suitable for applications needing integrated diagnostics and protection without external discrete components. Consider the thermal performance and current rating relative to the specific load requirements and ambient operating conditions of the target application.

Part Context

This part belongs to Microchip's ATA68xx family of System Basis Chips, which are designed to simplify automotive electronic control unit (ECU) designs by combining power management and gate driving capabilities into a single package. These devices aim to reduce component count, board space, and development time for complex automotive power distribution networks.

Replacement Considerations

Consult official Microchip substitution guides for verified alternatives. Generic replacements may not match the integrated diagnostic features or specific automotive qualification levels. Verify functional equivalence and pin-to-pin compatibility before considering any substitute parts.
