Product details
Overview
MPF5200AMBA4ES from NXP Semiconductors is an automotive-grade power management IC (PMIC) designed as the primary core power supply for the S32R45 radar processor. It integrates two 8 A buck regulators (0.6 V–1.2 V, ±1.5 % accuracy), one-time programmable (OTP) memory for startup configuration, ASIL B safety compliance, and a 3.4 MHz I²C interface - enabling precise voltage sequencing and dynamic voltage scaling in automotive radar systems.
For engineers reviewing the MPF5200AMBA4ES datasheet, MPF5200AMBA4ES pinout, MPF5200AMBA4ES application, or MPF5200AMBA4ES equivalent, this device delivers deterministic startup behavior, fault-resilient state machine control, integrated thermal/voltage/UV/OV/ILIM monitoring, and fail-safe transition capability - all critical for functional safety–compliant ADAS radar power domains.
Technical Context
The MPF5200AMBA4ES implements a dual-buck architecture with independent SW1 and SW2 channels, each supporting 8 A output current, 6.25 mV programmable voltage steps, and configurable DVS timing. Its internal state machine enforces ASIL B–aligned self-test routines (ABIST, bandgap comparison, CRC-verified OTP load) before entering QPU_Off or System On states.
It features dedicated safety circuitry including watchdog timer with programmable WD_MAX_CNT, fail-safe counter (FS_CNT), OTP_FS_BYPASS control, and secure I²C write protection. The SYNC pin supports clock synchronization for multi-PMIC coordination, while PGOOD, RESETBMCU, and XFAILB provide system-level fault signaling and reset coordination.
Key Specifications

Pinout & Package
MPF5200AMBA4ES uses a 32-pin HWQFN (SOT2039-2(SC)) package with wettable flank and 0.5 mm pitch. Exposed pad must be connected to AGND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1LX (pins 1,31,32) | SW1 switching node | Connects to high-side MOSFET drain and inductor - requires low-inductance layout for EMI control. |
| SW1IN (pins 2–4) | SW1 input supply | Power input for buck regulator 1 - paralleled pins support 8 A current delivery with reduced trace resistance. |
| SW1FB (pin 9) | SW1 feedback node | Resistor-divider input for output voltage regulation - sets 0.6 V–1.2 V range with 6.25 mV resolution. |
| V1P5D (pin 10) | 1.5 V LDO output | Always-on 1.5 V supply for internal logic and OTP - powers VDDIO and enables I²C communication before main regulators start. |
| TBBEN (pin 11) | Test-before-boot enable | Activates ASIL B self-test sequence on LP_Off → QPU_Off transition - required for safety-critical boot validation. |
| SCL/SDA (pins 18,17) | I²C serial interface | 3.4 MHz bidirectional bus - supports runtime configuration, fault register reads, and secure register writes. |
| RESETBMCU (pin 8) | Processor reset output | Open-drain active-low signal released after successful power-up sequencing - directly controls S32R45 reset assertion timing. |
| PGOOD (pin 7) | Power-good status | Open-drain indicator asserting when both buck outputs are within regulation - used for system-level power sequencing handshaking. |
| XFAILB (pin 6) | Fault signaling I/O | Bidirectional pin for external fail-safe coordination - can trigger MCU interrupt or drive external safety controller during fault events. |
| SYNC (pin 13) | Clock synchronization I/O | Configurable as input or output to align switching frequencies across multiple PMICs - reduces beat-frequency EMI in multi-radar modules. |
Key Features
| Feature | Design Value |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPF5200AMBA2ES | OTP preprogrammed for LX2160A Ethernet use case; I²C address 0x0A; lacks S32R45-specific core sequencing. | Targeted at networking SoCs, not radar processors - different voltage ramp profiles and DVS timing parameters. | Select only for LX2160A-based gateway designs; incompatible with S32R45 core power requirements. |
| MPF5200AMBA3ES | OTP preprogrammed for LX2160A DDR use case; I²C address 0x0B; optimized for memory rail stability, not core voltage agility. | Designed for DDR4/DDR5 memory power domains - fixed 1.1 V output, no DVS support, different fault response thresholds. | Not suitable for S32R45 core supply; use only in memory subsystems where DDR-specific regulation and timing apply. |

FAQ
What is the primary target application for MPF5200AMBA4ES?
The MPF5200AMBA4ES is specifically designed as the core power management IC for the NXP S32R45 automotive radar processor. It delivers tightly regulated 0.6 V–1.2 V supplies with ±1.5 % accuracy, ASIL B–compliant safety features, and OTP-programmed sequencing optimized for radar ECU boot timing and dynamic voltage scaling requirements - distinguishing it from variants intended for LX2160A or memory rails.
Does MPF5200AMBA4ES support dynamic voltage scaling (DVS) for the S32R45 processor?
Yes, MPF5200AMBA4ES supports full DVS for both SW1 and SW2 buck regulators, with 6.25 mV programmable voltage steps across the 0.6 V–1.2 V range. Its OTP memory stores DVS timing parameters and transition sequences, while the 3.4 MHz I²C interface allows runtime adjustment - enabling S32R45 performance mode transitions (e.g., low-power idle to high-resolution Doppler processing) without external intervention.
How does the ASIL B safety functionality manifest in MPF5200AMBA4ES operation?
MPF5200AMBA4ES implements ASIL B safety through hardware-enforced self-tests (ABIST, bandgap comparison, mirror-register CRC), fail-safe state transitions on triple self-test failure, programmable watchdog counters (WD_MAX_CNT), and dedicated safety registers (FS_CNT, OTP_FS_BYPASS). These features are activated via TBBEN and validated before RESETBMCU release - providing objective evidence of power integrity required for ISO 26262 certification in radar applications.
What package type and thermal characteristics does MPF5200AMBA4ES use?
MPF5200AMBA4ES uses a 32-pin HWQFN (SOT2039-2(SC)) package measuring 5 mm × 5 mm × 0.68 mm with wettable flank and exposed thermal pad. Its thermal resistance is RθJC(bottom) = 3.3 °C/W, enabling efficient heat transfer to PCB ground planes - critical for maintaining ≤125 °C ambient operation in sealed radar enclosures under sustained 8 A load conditions.
Can MPF5200AMBA4ES be used with processors other than the S32R45?
While MPF5200AMBA4ES is OTP-programmed for S32R45 core power sequencing and safety requirements, its fundamental buck regulation, I²C interface, and safety monitoring functions remain usable with other processors. However, S32R45-specific timing, DVS profiles, and fail-safe behaviors are hardcoded in OTP - so non-S32R45 use would require custom OTP programming by NXP or authorized partners, and safety certification would need revalidation.
