DA9061-XXAM1-AT

Power Management - Specialized Overview

The DA9061-XXAM1-AT is a system power management IC (PMIC) from the DA9061 series, manufactured by Renesas Electronics. It provides up to 8.5A of total output current through three high-current buck converters and four low-dropout linear regulators (LDOs). The device features an input voltage range of 2.8V to 5.5V and operates within a junction temperature range of -40°C to +125°C. It utilizes a 40-pin QFN package with a 0.5mm pitch. The part includes programmable sequencing, a watchdog timer, and an RTC with battery charger capabilities.

Power Management - Specialized Procurement Notes

Verify the specific suffix '-AT' against official Renesas documentation to confirm if it denotes automotive qualification or a specific tape-and-reel packaging variant distinct from standard tray versions. Ensure the OTP programming status aligns with project requirements, as finalized parts may be non-cancellable. Confirm availability through authorized distributors given potential restricted supply conditions.

Power Management - Specialized Selection Notes

Select this PMIC for designs requiring a compact solution for multi-core processors like i.MX or R-CAR families. The integrated power switches eliminate external FETs, reducing board space. Consider the 3MHz switching frequency for compatibility with low-profile inductors. Verify that the 8.5A total current capacity meets the peak load demands of the target SoC and peripheral subsystems.

Power Management - Specialized Part Context

The DA9061 series represents a scalable family of system PMICs designed for demanding embedded applications. This component sits alongside variants like the DA9061-A and DA9061-XXAMC, offering a balance of high current density and feature richness. It targets markets requiring robust power management with minimal external component count.

Power Management - Specialized Replacement Considerations

Consult official substitution lists for equivalents such as the DA9061-A or DA9061-XXAMC. Verify pin-to-pin compatibility and electrical parameter alignment before replacement. Note that suffix changes may indicate differences in packaging or programming status rather than functional changes.
