ATA6831-PISW

Overview

The ATA6831-PISW is a triple half-bridge driver integrated circuit manufactured by Microchip Technology, formerly Atmel. It features internal high-side and low-side drivers with power MOSFETs, designed for automotive applications such as fuel injection systems and engine management. The device supports SPI and PWM interfaces for control. It operates within a supply voltage range of 4V to 140V and includes comprehensive protection features like overcurrent, overtemperature, and undervoltage lockout.

Feature Summary

• Integrates three half-bridge drivers with internal power MOSFETs for compact design
• Supports serial peripheral interface (SPI) and pulse width modulation (PWM) control modes
• Provides robust protection mechanisms including overcurrent, overtemperature, and short-circuit detection

Applications

• Automotive fuel injection systems
• Engine management units
• General purpose high-side and low-side switching in industrial environments

Procurement Notes

Verify the manufacturer origin carefully, as the component was originally developed by Atmel Corporation before its acquisition by Microchip Technology. Ensure the datasheet version matches the specific revision requirements for your application. Confirm RoHS compliance status if environmental regulations are a constraint for your project.

Selection Notes

Select this component when a single IC solution is required to drive multiple loads with minimal external components. It is suitable for designs needing isolated gate drive capabilities without discrete transistors. Consider the thermal performance and package type relative to the expected current load and ambient operating conditions.

Part Context

This part belongs to the ATA683x family of triple half-bridge drivers. It is functionally similar to the ATA6832 but may differ in temperature ratings or specific electrical characteristics. The PISW suffix indicates a specific package variant, typically a plastic surface-mount package, distinct from other packaging options available in the series.

FAQ

What control interfaces does the ATA6831 support?

The device supports both Serial Peripheral Interface (SPI) for configuration and monitoring, and Pulse Width Modulation (PWM) for direct speed or duty cycle control.

Does the ATA6831 include internal power switches?

Yes, it integrates high-side and low-side power MOSFETs for each of the three half-bridges, eliminating the need for external discrete transistors.
