MPQ79720FS-AEC1

MPSafe^TM, ASIL-D, 8-Channel Power Sequencer, AEC-Q100 Qualified

概要

The MPQ79720FS-AEC1 is an 8-channel, functional safety power sequencer engineered to provide precise power sequencing and safety functions for automotive advanced driver-assistance systems (ADAS) and autonomous driving platforms.

The device’s configurability and flexibility enable design reuse across different applications and system-on-chip (SoC) generations.

The MPQ79720FS-AEC1 contains a crystal driver, a real-time clock (RTC) with an alarm function, a configurable watchdog that can be accessed through the I²C interface, and active-low system reset and interrupt outputs.

Safety mechanisms such as built-in self-testing (BIST) provide high diagnostic coverage, which helps the system achieve its target ASIL rating.

The MPQ79720FS-AEC1 is available in a QFN-24 (4mmx4mm) package with wettable flanks, and is available in AEC-Q100 Grade 1.
