ATA6836C-TIQY

Overview

The ATA6836C-TIQY is a hex half-bridge gate driver manufactured by Microchip Technology, housed in a 24-pin TQFP package. It integrates six independent half-bridge drivers controlled via serial input. The device supports a supply voltage range of 5.5V to 40V and delivers peak output currents up to 1A per channel. It operates within an extended temperature range of -40°C to +150°C TJ, ensuring reliability in automotive environments.

Feature Summary

• Integrates six independent half-bridge drivers for multi-phase motor control applications
• Features serial input control interface for simplified system integration
• Designed with robust protection mechanisms suitable for harsh automotive conditions

Applications

• Brushed DC motor control in automotive systems
• General purpose motor driving applications requiring multiple channels
• Automotive body electronics and zone ECU implementations

Procurement Notes

Verify the specific suffix TIQY against official Microchip documentation to confirm package type and tape/reel specifications. Confirm end-of-life status or obsolescence notices prior to design-in, as availability may be limited. Ensure compatibility with existing PCB footprints and thermal management requirements for the TQFP-24 form factor.

Selection Notes

Select this component when a high-channel-count half-bridge solution is required for brushed DC motors. Compare against the ATA6838 series if higher current ratings or different pinouts are needed. Verify that the serial control interface aligns with the host microcontroller's communication capabilities and that the operating voltage range matches the system power supply.

Part Context

This part belongs to the ATA68xx family of hex half-bridge drivers from Microchip (formerly Atmel). These devices are specifically engineered for automotive applications, offering integrated control and power stages. The family includes variants like the ATA6836 and ATA6838, differentiated by current capabilities and temperature grades, providing scalable solutions for various motor control needs.

Replacement Considerations

Direct substitutes include the ATA6836-PXQW or ATA6836C-PXQW for QFN packages, though pinout compatibility must be verified. The ATA6838 series offers similar functionality with potentially different electrical characteristics.
