ARG82801KLVATR-1

Overview

The ARG82801KLVATR-1 is a specialized Power Management IC (PMIC) from Allegro MicroSystems, designed for safety-related systems. It features nine outputs, including one buck or buck/boost converter and four linear regulators (LDOs). The device operates with an input voltage range of 3.8V to 36V and supports switching frequencies up to 2.2MHz. It is housed in a 38-eTSSOP package with exposed pad and is qualified to AEC-Q100 standards for automotive applications.

Feature Summary

• Integrated multi-output power management solution combining switching and linear regulation topologies
• Designed specifically for ASIL-D safety-related system applications
• Automotive-grade qualification ensuring reliability under harsh operating conditions

Applications

• ASIL-D compliant automotive electronic control units
• Safety-critical vehicle subsystems requiring redundant power paths
• Advanced driver assistance systems (ADAS) power architectures

Procurement Notes

Verify the specific suffix -1 against official datasheets to confirm pinout and functional configuration differences from standard variants. Ensure compatibility with your board layout regarding the 38-eTSSOP exposed pad thermal requirements. Confirm moisture sensitivity level handling procedures during assembly to prevent package damage.

Selection Notes

Select this component when designing for high-integrity automotive environments requiring integrated power sequencing and regulation. The combination of buck/boost and LDO outputs reduces external component count compared to discrete solutions. Ensure the 3.8V to 36V input range aligns with your vehicle's electrical system specifications.
