MPQ79700FS-AEC1

MPSafe™ 12-Channel ASIL-D Power Sequencer, AEC-Q100 Qualified

Description

The MPQ79700FS is a 12-channel functional safety power sequencer designed for automotive advanced driver assistance systems (ADAS) and autonomous driving platforms, which provide the essential controls and sequencing for the entire platform.

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

The MPQ79700FS contains a crystal driver, as well as a real-time clock (RTC) with an alarm function. The device also contains a configurable watchdog, which is accessible via the I²C interface, along with active-low system reset and interrupt outputs.

Integrated safety mechanisms such as the built-in self-test (BIST) provide high diagnostic coverage, which allows the system to achieve the target ASIL rating. It is developed under MPS’ advanced MPSafe™ Functional Safety Product Development process, which has been independently certified to meet ISO26262 guidelines.

The MPQ79700FS is available in a QFN-24 (4mmx4mm) package with wettable flanks, and is AEC-Q100 Grade 1 qualified.
