Product details
Overview
MPF5200AMBA1ES from NXP Semiconductors is an automotive-grade power management IC (PMIC) designed as the primary core power supply for the LX2160A Ethernet application processor. It integrates two 8 A buck regulators (0.6 V–1.2 V, ±1.5 % accuracy), ASIL B safety monitoring, one-time programmable (OTP) configuration storage, and a 3.4 MHz I²C interface - enabling precise, sequenced, and fault-resilient power delivery in high-performance automotive networking systems.
For engineers reviewing the MPF5200AMBA1ES datasheet, MPF5200AMBA1ES pinout, MPF5200AMBA1ES application, or MPF5200AMBA1ES equivalent, this device delivers deterministic startup sequencing, real-time DVS control, thermal/UV/OV/ILIM fault protection, and fail-safe state transitions - critical for functional safety compliance in Ethernet-based ADAS and infotainment platforms.
Technical Context
The MPF5200AMBA1ES implements a dual-buck architecture with independent SW1 and SW2 channels, each supporting dynamic voltage scaling, spread-spectrum modulation, and configurable current limiting. Its integrated state machine handles full power-up/down sequencing, self-test execution (ASIL B), and watchdog-triggered fail-safe transitions without MCU intervention.
It features dedicated analog and power ground domains (AGND, SWGND), OTP-programmed startup defaults, and hardware-enforced safety mechanisms including ABIST, CRC-protected register loading, dual bandgap monitoring (BG1/BG2), and programmable fault counters (FS_CNT, FAULT_CNT) - all validated per AEC-Q100 and aligned with ISO 26262 ASIL B requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Buck Regulators | Two independent 8 A buck converters (SW1/SW2), output range 0.6 V–1.2 V, ±1.5 % accuracy at load - enables precise core rail regulation for LX2160A Ethernet SoC. |
| I²C Interface | 3.4 MHz high-speed interface - supports rapid runtime reconfiguration of voltage, sequencing, and protection thresholds during system operation. |
| Safety Certification | ASIL B compliant with ABIST, dual-bandgap monitoring, CRC-verified OTP loading, and fail-safe shutdown - meets automotive functional safety requirements without external safety monitors. |
| Thermal Performance | RθJC(bottom) = 3.3 °C/W - enables efficient heat extraction through exposed pad to PCB ground plane for sustained 8 A operation in compact automotive modules. |
| Operating Temperature | −40 °C to +125 °C ambient - qualified for under-hood and head-unit environments per AEC-Q100 Grade 2. |
| Package | 32-pin HWQFN (5 mm × 5 mm × 0.68 mm), wettable flank - supports automated optical inspection (AOI) and robust solder joint reliability in automotive production. |
| Startup Configuration | One-time programmable (OTP) memory stores default voltages, sequencing order, and safety thresholds - eliminates external resistor networks and reduces BOM count by up to 12 components. |
Pinout & Package
MPF5200AMBA1ES uses a 32-pin HWQFN (SOT2039-2(SC)) package with wettable flank and 0.5 mm pitch. The exposed pad must be connected to AGND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1IN (pins 2–4) | SW1 input supply | Accepts 0.3 V–5.5 V input; three parallel pins reduce trace resistance and improve current handling for 8 A buck channel. |
| SW1LX (pins 1, 31–32) | SW1 switching node | Connects to external high-side MOSFET gate driver output; multiple pins minimize inductance and EMI in high-frequency (up to 2.2 MHz) switching path. |
| SW2IN (pins 21–23) | SW2 input supply | Dedicated input domain for second 8 A buck regulator - enables independent input sourcing or redundancy for critical rails. |
| SW2LX (pins 24–26) | SW2 switching node | High-current switching node with low-inductance routing; supports dual-phase or independent operation with SW1. |
| V1P5D (pin 10) | 1.5 V LDO output | Always-on 1.5 V supply for internal logic and I/O buffers; powers VDDIO and enables I²C communication before main regulators start. |
| SCL/SDA (pins 18/17) | I²C interface | 3.4 MHz bidirectional bus - allows real-time voltage tuning, fault logging, and safety status readback during system run time. |
| PGOOD (pin 7) | Power-good indicator | Open-drain output asserting after both buck outputs stabilize within ±1.5 % - used to enable downstream logic or trigger processor reset release. |
| RESETBMCU (pin 8) | Processor reset signal | Active-low reset output controlled by OTP-programmed sequence - ensures LX2160A exits reset only after stable core rail establishment. |
| TBBEN (pin 11) | Test-before-boot enable | Hardware input initiating ASIL B self-test before power-up - mandatory for safety-critical boot sequences in automotive ADAS. |
| XFAILB (pin 6) | External fail-safe input | Bidirectional pin for external fault injection or cascaded safety signaling - triggers immediate fail-safe transition when asserted low. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPF5200AMBA2ES | I²C address fixed at 0x0A; preprogrammed for DDR rail configuration on LX2160A | Optimized for memory subsystem power, not core logic - lacks OTP flexibility for custom sequencing | Select only when DDR-specific voltage and timing are required; not interchangeable for core rail use. |
| MPF5200AMBA4ES | OTP configured for S32R45 radar processor; different default voltages and power-up order | Targeted at radar SoCs with distinct thermal and sequencing profiles - incompatible with LX2160A boot flow | Use exclusively with NXP S32R45; requires separate validation for LX2160A due to mismatched OTP settings. |

FAQ
What is the primary application target for MPF5200AMBA1ES?
MPF5200AMBA1ES is specifically configured for the LX2160A Ethernet application processor in automotive gateways. Its OTP programming matches the LX2160A's core voltage requirements (0.6 V–1.2 V), power-up sequencing, and I²C address (0x0B), enabling plug-and-play integration without external configuration components. This makes MPF5200AMBA1ES the designated PMIC for Ethernet-based vehicle networking systems.
Does MPF5200AMBA1ES support functional safety certification?
Yes, MPF5200AMBA1ES is ASIL B certified per ISO 26262. It includes hardware-level safety features such as analog built-in self-test (ABIST), dual-bandgap monitoring, CRC-protected OTP register loading, programmable fault counters (FS_CNT, FAULT_CNT), and fail-safe state transitions - all verified and documented in NXP's PF5200 safety manual. These capabilities eliminate the need for external safety monitors in ASIL B architectures.
How does the OTP memory in MPF5200AMBA1ES reduce system design complexity?
The OTP memory in MPF5200AMBA1ES stores voltage setpoints, power-up/down sequencing order, watchdog timeout values, and safety thresholds - removing the need for external resistors, timing capacitors, or configuration EEPROMs. This reduces BOM count by up to 12 passive components, eliminates layout-sensitive analog tuning networks, and guarantees repeatable startup behavior across production units without firmware dependency.
What package type and thermal characteristics does MPF5200AMBA1ES use?
MPF5200AMBA1ES uses a 32-pin HWQFN (SOT2039-2(SC)) package with wettable flank, 5 mm × 5 mm body, and 0.68 mm height. Its thermal resistance is RθJC(bottom) = 3.3 °C/W, enabling efficient heat transfer from the die to the PCB ground plane. This allows sustained 8 A operation at 125 °C ambient without derating - critical for compact, sealed automotive modules.
Can MPF5200AMBA1ES be reconfigured after power-up?
Yes, MPF5200AMBA1ES supports full runtime reconfiguration via its 3.4 MHz I²C interface. Engineers can adjust output voltages, modify DVS profiles, update fault thresholds, read real-time telemetry (e.g., temperature, current), and log fault events - all while the LX2160A SoC remains operational. This enables adaptive power management, field diagnostics, and over-the-air updates without requiring hardware changes or system reset.
