ATA6829-T3SY

Overview

The ATA6829-T3SY is a Single Input Multiple Output (SIMO) DC-DC converter manufactured by Microchip Technology. It integrates multiple switching regulators within a single package to provide independent power rails for automotive applications, specifically targeting the ATmega128RFA1 microcontroller. The device features an integrated high-side driver and supports various output configurations to meet the specific voltage and current requirements of connected peripherals in low-power wireless sensor networks.

Feature Summary

• Integrates multiple DC-DC converters into a single solution to reduce component count
• Includes an integrated high-side driver for external switch control
• Designed for low-power operation in battery-supplied systems
• Supports flexible output configuration for diverse peripheral needs

Applications

• Power supply for ATmega128RFA1-based wireless sensor nodes
• Low-power automotive electronic control units
• Battery-operated IoT devices requiring multiple voltage rails

Procurement Notes

Verify the exact suffix 'T3SY' against the official Microchip datasheet to confirm tape-and-reel packaging specifications and temperature grade. Ensure compatibility with the target system's input voltage range and thermal management requirements before finalizing procurement.

Selection Notes

Select this component when designing systems based on the ATmega128RFA1 that require multiple regulated voltages from a single source. It is suitable for space-constrained designs where minimizing passive components and PCB area is critical. Evaluate the total output current capability against the load requirements of all connected rails.

Part Context

This part belongs to the ATA6829 family of SIMO converters developed for automotive and industrial applications. It is closely associated with Microchip's AVR XMEGA and ATmega RFA1 series microcontrollers, providing a complete power management solution for wireless connectivity modules.

Replacement Considerations

Check for direct pin-compatible alternatives within the ATA68xx series or newer generations of SIMO converters from Microchip. Verify that any substitute maintains the same output voltage levels and current capabilities required by the ATmega128RFA1.
