Overview
The ARG81402KETATR is a Power Management IC (PMIC) designed for safety-related automotive systems. It integrates a synchronous buck pre-regulator, five linear regulators, a watchdog timer, and an SPI interface. The device supports high-reliability applications requiring robust power sequencing and monitoring capabilities within a compact package.
Feature Summary
- Integrates a synchronous buck pre-regulator with five internal linear regulators for comprehensive power management.
- Includes a pulse-width watchdog timer and system reset functions to ensure operational safety in critical environments.
- Features an SPI interface for configuration and status monitoring, enabling flexible system integration.
Applications
- Safety-critical automotive electronic control units
- Advanced driver assistance systems (ADAS) power architectures
- Industrial motor control systems requiring high reliability
Procurement Notes
Verify the specific suffix KETATR against the manufacturer's official datasheet to confirm pinout and thermal characteristics. Ensure compatibility with your PCB layout requirements. Confirm RoHS compliance status through the latest production documentation before finalizing procurement orders.
Selection Notes
Select this component when a single-chip solution is required for safety-related systems needing both switching and linear regulation. Consider the integrated watchdog and SPI features for simplified design compared to discrete solutions. Evaluate thermal performance and package constraints during the initial design phase.
Part Context
This part belongs to the ARG8140x family of automotive PMICs from Allegro MicroSystems. These devices are engineered to meet stringent automotive quality standards, providing integrated power management solutions that reduce component count and board space in complex electronic systems.
Replacement Considerations
Consult the manufacturer's obsolescence notices and recommended replacement lists. Verify functional equivalence and pin-to-pin compatibility if substituting with other ARG8140x variants or updated revisions.
