ATA6826-TUQY

Overview

The ATA6826-TUQY is a triple half-bridge driver manufactured by Microchip Technology using DMOS technology. It features an SPI interface and is housed in a 14-SOIC package. The device supports a supply voltage range of 4.75V to 5.25V and handles load voltages from 7V to 40V. Each channel provides an output current of 1A with a peak output of 1.3A. The typical on-resistance is 1.5 Ohms. It operates within a junction temperature range of -40°C to 150°C.

Feature Summary

• Integrates three independent half-bridge drivers for simultaneous control of multiple loads.
• Utilizes Serial Peripheral Interface (SPI) for digital input control and status feedback.
• Incorporates DMOS technology to drive inductive, capacitive, and resistive loads efficiently.

Applications

• DC motor control systems
• Incandescent bulb driving applications
• Resistive load management

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified partners. Confirm the specific suffix TUQY matches the required 14-SOIC package variant. Check for RoHS compliance documentation as indicated in official datasheets. Ensure storage conditions adhere to moisture sensitivity level 1 requirements to prevent package damage prior to soldering.

Selection Notes

Select this component when a compact solution for driving three separate half-bridges is required. The 1A per channel rating suits low-power DC motors and lighting loads. The SPI interface allows for precise digital control without excessive GPIO usage. Consider the 14-SOIC footprint for surface mount assembly constraints.

Part Context

This part belongs to the ATA6826 family of integrated gate drivers designed for automotive and industrial applications. It combines control logic with power stages to simplify circuit design. The device is classified under Power Management ICs (PMIC) specifically as a Half-Bridge Driver. It replaces discrete MOSFET arrangements with a single integrated solution.

Replacement Considerations

The manufacturer lists this part as obsolete. Verify if the ATA6826N-TUQY variant offers equivalent pin compatibility or updated specifications before substitution. Consult Microchip technical support for approved alternative components that maintain the same electrical characteristics and package dimensions.
