ATA6836-TIQY

Overview

The ATA6836-TIQY is a six-channel half-bridge gate driver manufactured by Microchip Technology. It is designed for controlling DC motors, bulbs, and resistive loads using Power MOSFETs. The device operates within a supply voltage range of -300 mV to 40 V and delivers a peak output current of 650 mA. It features integrated protection mechanisms including open load detection, over-temperature shutdown, short-circuit protection, and under-voltage lockout (UVLO). The component is housed in a 28-SO package and supports surface-mount installation.

Feature Summary

• Integrated protection against open load conditions, over-temperature events, short circuits, and under-voltage lockout.
• Designed for driving high-side and low-side Power MOSFETs in half-bridge configurations.
• Capable of handling inductive, capacitive, and resistive loads.

Applications

• DC motor control systems
• Bulb driving applications
• Resistive load management

Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm availability through authorized distributors or surplus suppliers. Ensure compatibility with existing PCB footprints and design requirements. Check for potential tariff implications if shipping to specific regions. Validate that alternative components meet all electrical specifications if substitution is necessary.

Selection Notes

Select this driver for applications requiring robust protection features in half-bridge topologies. Consider the 650 mA peak output current capability when sizing external MOSFETs. Evaluate the thermal performance given the operating temperature range. Verify that the 28-SO package fits the mechanical constraints of the target enclosure. Assess the need for UVLO and short-circuit protection in the specific circuit design.
