ATA6836C-TIQW

Overview

The ATA6836C-TIQW is a six-channel half-bridge gate driver manufactured by Microchip Technology, designed for driving power MOSFETs in automotive and industrial applications. It operates with a supply voltage range of 4.75 V to 5.25 V and supports load voltages from 5.5 V to 40 V. The device features an SPI interface for configuration and status monitoring. Each channel provides a peak output current of 650 mA with typical on-resistances of 1 ohm for both high-side and low-side switches. Key electrical parameters include rise and fall times of 13 ns, a quiescent current of 800 uA, and an operating temperature range of -40°C to +150°C TJ.

Feature Summary

• Integrates six independent half-bridge drivers with SPI control interface
• Includes comprehensive fault protection mechanisms such as over-temperature, short-circuit, and under-voltage lockout
• Supports open-load detection for diagnostic capabilities
• Designed for driving inductive, capacitive, and resistive loads

Applications

• DC motor control systems
• Automotive lighting and bulb drivers
• Resistive load switching applications

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified agents. Confirm the specific suffix TIQW corresponds to the 28-SOIC package and cut tape packaging format. Check for recent Product Change Notifications (PCN) regarding manufacturing site updates or material changes. Ensure compliance with RoHS directives and verify lead-free status before integration into production designs.

Selection Notes

Select this component when a multi-channel half-bridge solution with integrated diagnostics is required. The SPI interface allows for flexible configuration and real-time status feedback. Consider the 650mA output capability and 40V load voltage rating against specific load requirements. Evaluate the thermal performance within the -40°C to +150°C junction temperature range for the intended application environment.
