Product details
Overview
MPF5024CMBA0ESR2 from NXP Semiconductors is an automotive-grade power management IC (PMIC) with four high-efficiency buck regulators (0.4 V–1.8 V, 2.5 A each), ASIL B safety compliance, OTP-based startup configuration, and 3.4 MHz I²C interface - deployed in i.MX 8/S32V processor power trees for infotainment systems.
For engineers reviewing the MPF5024CMBA0ESR2 datasheet, MPF5024CMBA0ESR2 pinout, MPF5024CMBA0ESR2 application, or MPF5024CMBA0ESR2 equivalent, this page delivers verified regulator specs, safety-critical monitoring features, QFN40 wettable flank package details, and automotive-qualified alternatives aligned to AEC-Q100 and functional safety requirements.
Technical Context
The MPF5024CMBA0ESR2 implements a deterministic state machine with ASIL B–validated self-test routines (ABIST, bandgap CRC, oscillator tolerance check), fail-safe transition logic (FS_CNT, OTP_FS_MAX_CNT), and configurable power-up sequencing via OTP or I²C. It supports VTT termination on SW2 and dynamic voltage scaling across all four buck stages.
Its safety architecture includes independent UV/OV/ILIM fault detection per regulator, thermal shutdown at 150 °C, watchdog monitoring with programmable counter, and secure I²C write protection for safety registers - all enabled only in ASIL B variants like MPF5024CMBA0ESR2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Buck regulators | Four independent 0.4–1.8 V, 2.5 A buck converters with VTT mode on SW2 and 6.25 mV output step resolution. |
| Input voltage range | VIN: 0.9–5.5 V (max 1800 sec lifetime exposure above 5.5 V); SWxIN: −0.3 to 6.0 V absolute max. |
| I²C interface | High-speed 3.4 MHz I²C with CRC, write protection, and secure register access for safety-critical configuration. |
| Safety certification | AEC-Q100 qualified; ASIL B compliant with ABIST, dual bandgap monitoring, fault counters, and fail-safe state transitions. |
| Thermal performance | Junction-to-board thermal resistance ΨJB = 12.3 °C/W (2s6p PCB); max operating TJ = 150 °C. |
| Package | HVQFN40 (6 mm × 6 mm × 0.9 mm), wettable flank, exposed pad, 0.5 mm pitch, rated for 125 °C ambient. |
| Startup configuration | One-time programmable (OTP) memory stores default voltages, sequencing order, soft-start timing, and safety settings - eliminating external resistors and reducing BOM count. |
Pinout & Package
HVQFN40 package with wettable flank, 6 mm × 6 mm body, 0.5 mm pitch, and thermally enhanced exposed pad (EPAD) connected to AGND. Pin 1 = SW2FB; pin 40 = SW1FB; EPAD = ground reference and primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1FB–SW4FB (pins 1,10,11,40) | Regulator feedback inputs | Resistive divider nodes for precise 0.4–1.8 V output regulation; support dynamic voltage scaling and margining. |
| EN1–EN4 (pins 38,39,13,12) | Independent enable inputs | Asynchronous control of each buck stage; allows flexible sequencing, power gating, and low-power states. |
| PGOOD1–PGOOD4 (pins 19,20,32,33) | Per-regulator power-good outputs | Open-drain status signals indicating valid output voltage; used for cascaded sequencing and fault isolation. |
| PGOOD (pin 26), INTB (pin 25) | Global status and interrupt | Combined PGOOD reflects all regulators; INTB signals faults (OV/UV/thermal/watchdog) to host MCU via open-drain line. |
| SDA/SCL (pins 29,30) | I²C bidirectional interface | 3.4 MHz communication for runtime reconfiguration, telemetry readback, and safety register updates. |
| XFAILB (pin 21), TBBEN (pin 35) | Safety and test control | XFAILB enables external fail-safe assertion; TBBEN selects built-in self-test mode during LP_Off → self-test transition. |
| VDDOTP (pin 28) | OTP programming supply | 10 V max input for fuse loading; OTP programming restricted to NXP or authorized third parties for production units. |
| AGND (pin 18), EPAD | Analog ground and thermal pad | Low-noise reference plane for analog circuits; EPAD must be soldered to PCB ground plane for thermal and EMI performance. |
Key Features
| Feature | Design Value |
|---|---|
| ASIL B functional safety architecture | Validated self-test (ABIST, bandgap CRC, oscillator tolerance), fault counters (FS_CNT, FAULT_CNT), and fail-safe state transitions - certified per ISO 26262 requirements. |
| OTP-configurable power tree | Stores startup voltage, sequencing order, soft-start time, and safety thresholds - eliminates 12+ external resistors and simplifies layout for i.MX 8/S32V designs. |
| VTT termination on SW2 | Enables DDR memory termination with adjustable VTT tracking; supports JEDEC-compliant DDR3/DDR4/LPDDR4 interfaces without external components. |
| Spread-spectrum and manual frequency tuning | Reduces EMI peak emissions by modulating switching frequency; manual tuning allows optimization for specific noise-sensitive bands in automotive cabins. |
| Thermal-aware state machine | Monitors junction temperature in real time; triggers thermal shutdown at 150 °C and adjusts regulator behavior before critical limits are reached. |
| Secure I²C register protection | Prevents unauthorized writes to safety-critical registers (e.g., fault masks, watchdog timeout) using I2C_SECURE_EN and OTP_I2C_SECURE_EN bits. |

How does the OTP memory in MPF5024CMBA0ESR2 reduce external components?
The MPF5024CMBA0ESR2 uses one-time programmable (OTP) memory to store startup configurations - including output voltages, sequencing order, soft-start timing, and safety thresholds - eliminating up to 12 external resistors and discrete sequencers. This reduces BOM count, PCB area, and design validation effort while ensuring repeatable, production-ready power-up behavior for MPF5024CMBA0ESR2.
Can MPF5024CMBA0ESR2 support DDR memory termination?
Yes, MPF5024CMBA0ESR2 supports VTT termination on SW2 regulator, enabling direct DDR3/DDR4/LPDDR4 memory bus termination without external components.
