MPQ70160FS-AEC1

MPSafe^TM, ASIL D, 6.5V, PMIC with 6 Buck Converters with Dual 4A, Dual 3A, and Dual 1A for Automotive ADAS, AEC-Q100 Qualified

Description

The MPQ70160FS is a power management IC (PMIC) designed to operate from 5V buses to power a variety of advanced driver assistance system (ADAS) system-on-chips (SOCs). Six integrated buck converters power a variety of target rails. Constant-frequency peak current mode control offers fast transient performance with stable frequency.

The fixed 2MHz switching frequency (f_SW) during continuous conduction mode (CCM) mode greatly reduces the external inductor and capacitor count. Full protection features include under-voltage lockout (UVLO), over-current protection (OCP), over-voltage protection (OVP), and thermal shutdown.

With the integration of sophisticated functional safety features such as built-in self-testing (BIST) and diagnostics, this ASIL-certified device supports applications with a high automotive safety integrity level up to ASIL D. It is developed under MPS's advanced MPSafe^TM Functional Safety Product Development process, which has been independently certified to meet ISO26262 guidelines.

A configurable watchdog is implemented in the MPQ70160FS and provides a window, as well as question-answer modes. The PMBus interface provides packet error checking (PEC), and the integrated multi-page one-time programmable (MOTP) memory allows for a high degree of configurability.

The MPQ70160FS is available in a QFN-32 (5mmx5mm) package, and is AEC-Q100 Grade 1 qualified.
