MC33FS8415GJKS

Power Management - Specialized Overview

The MC33FS8415GJKS is an automotive, functionally safe multi-output power supply integrated circuit from the FS84 series. It operates within a DC input voltage range of 5.1 V to 60 V and features multiple switch-mode power supplies (SMPS) and linear regulators (LDOs). Designed for high reliability, it achieves ASIL B safety ratings through independent safety monitoring. The device supports low standby currents of 10 µA in sleep mode and utilizes a 32-bit SPI interface with CRC for secure communication. It is housed in an HVQFN-56 package suitable for surface mount installation.

Power Management - Specialized Feature Summary

• Provides multiple SMPS and LDO outputs to power S32 microcontrollers and other system components
• Integrates independent safety monitoring circuits to achieve ASIL B functional safety compliance
• Features programmable power sequencing and specific functions via one-time programmable (OTP) memory
• Supports low-power operation with very low sleep current consumption in shutdown modes

Power Management - Specialized Applications

• Advanced Driver Assistance Systems (ADAS) sensor power management
• Automotive camera systems
• Automotive radar applications
• LiDAR sensor power distribution

Power Management - Specialized Procurement Notes

Verify the exact suffix against official NXP documentation to confirm package type and OTP configuration. Ensure compatibility with the target S32 microcontroller family. Check for RoHS compliance status and humidity sensitivity classification before integration into production designs.

Power Management - Specialized Selection Notes

Select this component for ADAS applications requiring ASIL B certified power management. It serves as a primary companion chip for S32 microcontrollers. Consider the KS suffix variant for new designs if HVQFN-56 packaging is required. Evaluate OTP programming needs during the development phase using compatible evaluation kits.

Power Management - Specialized Part Context

This part belongs to the FS8400 series of System Basis Chips (SBCs). It is developed following ISO 26262 standards and meets AEC-Q100 requirements. The FS84 series offers scalability and pin-to-pin compatibility with the FS85 series, allowing for flexible design implementations across different automotive electronic control units.

Power Management - Specialized Replacement Considerations

For new designs using the HVQFN-56 package, NXP recommends using parts with the KS suffix, such as MC3xFS84xxKS. The FS84 and FS85 series are pin-to-pin and software compatible, allowing for potential substitution within that family.
