Allegro MicroSystems launches ASIL-D PMIC for electromechanical braking
The new A81415 integrates a wheel-speed sensor interface and is designed to remove as many as nine external components, aimed at cutting bill-of-materials costs and improving safety-critical loop latency.
Allegro MicroSystems (NASDAQ: ALGM) has introduced the A81415, described as the first ASIL-D certified PMIC for braking systems that integrates a wheel-speed sensor interface, for use in electromechanical braking and brake-by-wire architectures, according to Yahoo Finance.
The single-chip design is meant to eliminate up to nine external components and free more board space, while consolidating power management and sensor decoding to reduce latency in safety-critical loops and to free MCU bandwidth for faster braking responses.
The company said the A81415 is built for demanding corner module electronics, with thermal robustness and vibration resistance, and is intended to support high-resolution sensing and clamping-force signals, with a fail-operational foundation for safety needs at the wheel.
Yahoo Finance also notes that the device is positioned as a migration path from 12V to 48V braking systems without requiring bulky external protection, and that it can help Tier 1 suppliers build simpler, more scalable foundations for next-generation software-defined vehicles.
