Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MC33FS8510A2ES is an automotive, functionally safe multi-output power supply IC. It focuses on ADAS and domain controller applications and is the primary companion chip for the S32 microcontroller.

The FS85 contains multiple switch mode and linear regulators with enhanced safety features and fail-safe outputs. This makes it a complete part of a safety orientated system with an ASIL D safety integrity rating.

Key Features

60V maximum input voltage for car and truck markets

Multiple SMPS and LDOs to power S32 microcontrollers etc.

Standby shutdown mode with very low sleep current (10µA)

32-bit SPI and IDC interface with CRC

ASIL D rated with independent safety monitoring devices

Power, sequencing and specific functions programmable from One Time Programmable (OTP) memory

Standard predefined OTPs supporting leading MCUs can be found in the "Ordering Information" chapter of the datasheet.

Customised OTP parts can be programmed during the development phase using the KITFS85SKTEVM board.

Custom OTPs can be supplied for production. Please contact your NXP sales channel (NXP or your reseller)

Custom OTP forms can be downloaded via the OTP configuration tool
