MPF5200AMBA4ES

Overview

The MPF5200AMBA4ES is a specialized automotive Power Management IC (PMIC) from the PF5200 series, designed for high-performance applications. It features three step-down DC/DC converters and one Low Dropout (LDO) regulator. The device operates within an input voltage range of 2.7 V to 5.5 V and supports a maximum output current of 8 A. It is housed in a HWQFN-32 package and functions reliably across a temperature range of -40°C to +125°C. This specific variant carries a QM Safety Level and is pre-programmed with One-Time Programmable (OTP) memory configurations tailored for S32R45 MCU support.

Feature Summary

• Integrates three efficient step-down DC/DC converters and one LDO regulator for comprehensive power distribution.
• Features pre-programmed OTP memory for flexible device configuration and specific application targeting.
• Includes advanced safety mechanisms such as programmable fault protection, thermal monitoring, and watchdog timers.
• Supports high-speed I²C communication at 3.4 MHz with CRC and write protection capabilities.

Applications

• Automotive systems utilizing S32R45 microcontrollers
• High-performance automotive electronic control units
• Power management subsystems requiring ASIL-B or QM safety levels

Procurement Notes

Verify the specific safety level designation, as documentation indicates both QM and ASIL-B variants within the same family. Confirm the OTP configuration matches the target MCU requirements, specifically S32R45 compatibility. Ensure the HWQFN-32 package footprint aligns with PCB design constraints. Check for any recent Product Change Notifications regarding manufacturing updates or material changes before finalizing procurement orders.

Selection Notes

Select this component when designing automotive platforms that require integrated power management for S32R45 processors. The pre-programmed nature simplifies production by eliminating custom OTP programming steps. Consider the 8 A total output capability and the 2.7 V to 5.5 V input range against system power budgets. Evaluate the need for QM versus ASIL-B safety integrity levels based on functional safety requirements.

Part Context

This part belongs to the PF5200 family of multi-channel PMICs developed by NXP Semiconductors. The family includes various pre-programmed variants optimized for different MCUs like LX2160A and LA1224. The MPF5200AMBA4ES is distinctively configured for S32R45 applications, offering a compact solution in a 32-pin package compared to larger alternatives in the portfolio.

Replacement Considerations

MPF5200AMBA1ES, MPF5200AMBA2ES, MPF5200AMBA3ES are alternative OTP configurations within the same hardware platform but target different MCUs such as LX2160A. Verify MCU compatibility before substitution. Other PF5200 variants may share electrical characteristics but differ in safety levels or pre-programmed settings.
