ATA6826C-TUQW

Overview

The ATA6826C-TUQW is a triple half-bridge DMOS output driver manufactured by Microchip Technology, housed in a 14-SOIC package. It operates with a supply voltage range of 4.75V to 5.25V and supports load voltages from 7V to 40V. The device features three half-bridge outputs capable of delivering up to 1.0A output current per channel, with a peak output of 1.3A. Typical on-resistance (RDSon) is 0.8Ω at 25°C, with a maximum of 1.5Ω at 150°C. Control is managed via an SPI interface, and the component functions within a junction temperature range of -40°C to 150°C.

Feature Summary

• Integrates three half-bridge outputs for simultaneous control of multiple loads
• Utilizes SPI interface for digital command and status monitoring
• Supports inductive, capacitive, and resistive load types

Applications

• DC motor control
• Lamp driving
• Resistive load actuation

Procurement Notes

Verify the specific suffix TUQW against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage requirements, as the device requires a 5V logic supply while supporting higher load voltages. Confirm that the SPI interface timing meets the host controller's specifications before integration.

Selection Notes

Select this component when a compact solution for driving three independent half-bridges is required. The integrated DMOS technology reduces external component count compared to discrete solutions. Consider the thermal performance given the RDSon variations across the operating temperature range. Verify that the 14-SOIC footprint fits the available PCB space constraints.

Part Context

This part belongs to the ATA6826 family of motor and ignition controllers. It is designed for automotive and industrial applications requiring reliable switching of low-power loads. The device integrates protection features typical of automotive-grade drivers, ensuring robust operation in electrically noisy environments.

Replacement Considerations

Check for direct pin-to-pin replacements such as the ATA6826-TUSY, noting differences in packaging or availability status. Verify that any substitute maintains the same SPI protocol and electrical characteristics, particularly the output current ratings and voltage tolerances.
