ALGM•ALGM•Allegro MicroSystems introduced the A81415, the industry's first ASIL-D-certified safety PMIC with an integrated wheel-speed sensor interface, eliminating up to nine external components and unlocking $4 in semiconductor BOM savings per vehicle. The single-chip solution frees over 50% of PCB area and supports 12V-to-48V brake-by-wire architectures.
Allegro MicroSystems introduced the A81415, the industry's first ASIL-D-certified Power Management IC integrating a wheel-speed sensor interface for electromechanical braking. This single-chip solution simplifies brake-by-wire design by combining power management and sensor decoding in one device.
On-chip WSSI decodes 2-level PWM and 3-level AK protocols without external decoders, eliminating up to nine components and delivering $4 in semiconductor BOM savings per vehicle. Integration frees over 50% of PCB area in corner module designs, offering OEMs significant board-space efficiencies.
ASIL-D certification, dual watchdogs, and built-in fault handling ensure fail-operational power delivery and accurate wheel-speed data under vibration and thermal stress. Low-noise LDO regulators and SPI data sharing reduce latency and free MCU bandwidth for faster braking response.
Built on automotive grade-0 process and paired with the APM81815 pre-regulator, the A81415 supports seamless migration from 12V to 48V corner modules without redesign or bulky protection. This fast-track chipset aids Tier 1 suppliers in deploying next-gen brake-by-wire architectures.
