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 (fSW) 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 MPSafeTM 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.
