Product details
Overview
MPF5023CMBA0ES from NXP Semiconductors is an automotive-grade power management IC (PMIC) with three high-efficiency buck regulators (0.4 V–1.8 V, 2.5 A each), ASIL B safety compliance, OTP-configurable startup sequencing, and 3.4 MHz I²C interface-designed for i.MX 8/S32V processor power delivery in infotainment systems.
For engineers reviewing the MPF5023CMBA0ES datasheet, MPF5023CMBA0ES pinout, MPF5023CMBA0ES application, or MPF5023CMBA0ES equivalent, this device delivers deterministic power sequencing, integrated watchdog/monitoring, thermal fault protection, and fail-safe state transitions critical for automotive functional safety validation.
Technical Context
The MPF5023CMBA0ES implements a safety-critical state machine with ASIL B–qualified self-test routines-including bandgap matching verification, mirror register CRC, ABIST, and oscillator tolerance checks-and transitions through LP_Off → Self-test → QPU_Off → Power-up → System ON states. It supports dynamic voltage scaling, multiphase configuration, and VTT termination on SW2.
Its architecture integrates OTP-programmable regulator enable order, soft-start timing, PGOOD monitoring per rail plus global PGOOD, and configurable sync pin for clock synchronization across multiple PMICs. The 40-pin HVQFN package enables thermal dissipation via exposed pad (RθJA = 26.8 °C/W, 2s6p).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Buck regulators | Three independent 0.4–1.8 V, 2500 mA buck converters with programmable current limit and spread-spectrum switching |
| Input voltage range | VIN: 0.9–5.5 V (UVDET threshold); absolute max 6.0 V - defines system-level input filtering and overvoltage clamping requirements |
| I²C interface | High-speed 3.4 MHz I²C with CRC, write protection, and secure register access - enables real-time dynamic voltage scaling during operation |
| Safety certification | ASIL B compliant per ISO 26262; includes watchdog timer, thermal shutdown, UV/OV/ILIM fault detection, and fail-safe state locking |
| Operating temperature | −40 °C to +125 °C ambient - qualified for under-hood automotive environments without derating |
| Package | HVQFN40 (6 mm × 6 mm × 0.9 mm, 0.5 mm pitch, wettable flank) - supports automated optical inspection and high thermal reliability |
| Startup configuration | One-time programmable (OTP) memory stores default output voltages, sequencing order, soft-start times, and safety thresholds - eliminates external resistor networks |
Pinout & Package
MPF5023CMBA0ES uses a 40-pin HVQFN package with wettable flank and exposed thermal pad (EPAD), optimized for automotive thermal cycling and solder joint reliability. Pin 1 is SW2FB; EPAD must be connected to AGND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1FB, SW2FB, SW3FB | Feedback inputs | Resistor-divider nodes for closed-loop regulation of each buck output; support 6.25 mV output step resolution |
| EN1, EN2, EN3 | Regulator enable inputs | Independent digital control of each buck converter; active-high, 1.8 V/3.3 V compatible logic levels |
| PGOOD1, PGOOD2, PGOOD3, PGOOD | Power-good outputs | Open-drain status signals indicating individual or global rail stability - used for processor reset coordination and fault isolation |
| RESETBMCU | Processor reset output | Open-drain MCU reset signal released after successful power-up sequence - synchronizes boot timing with supply readiness |
| WDI, TBBEN, XFAILB | Safety interface terminals | External watchdog input, test-bench bypass enable, and fail-safe trigger - enable ASIL B diagnostic coverage and fail-safe state entry |
| VDDIO, VDDOTP | Supply rails | VDDIO powers I/O circuitry (1.8 V or 3.3 V); VDDOTP supplies OTP programming block (up to 10 V) - require separate decoupling |
| SYNC | Clock synchronization I/O | Configurable as input or output to align switching frequencies across multiple PMICs - reduces EMI peak amplitude |
| EPAD | Thermal and electrical ground | Exposed copper pad beneath die - must be soldered to solid AGND plane for thermal conduction and noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| ASIL B self-test routine | Triple-execution bandgap matching, mirror register CRC, oscillator tolerance check, and ABIST - ensures integrity before system power-up |
| Fail-safe state transition | Hardware-locked shutdown on critical faults (e.g., thermal runaway, triple self-test failure) - prevents unsafe system re-entry |
| VTT termination mode | SW2 configurable as DDR VTT supply (0.4–1.8 V, 2.5 A) with tracking and current-sense capability - supports DDR4/LPDDR4 interfaces |
| Dynamic voltage scaling (DVS) | Real-time I²C-adjustable output voltage per buck regulator - enables processor performance-state coordination and power optimization |
| Programmable power sequencing | OTP-defined startup/shutdown order, soft-start ramp time, and delay between rails - eliminates need for external sequencer ICs |
| Thermal monitoring | On-die junction temperature sensing with programmable shutdown threshold (TSD) and warning interrupt - enables predictive thermal management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPF5023CMMA0ES | Same silicon, QM (Quality Management) grade - lacks ASIL B self-test, fail-safe state, and safety register set | Approved for non-safety-critical automotive modules (e.g., telematics, body control) but not infotainment or ADAS | Select only if functional safety certification is not required and cost sensitivity outweighs safety feature needs |
| PF5023CVNA0ES | Industrial-grade variant (105 °C max ambient), no ASIL B qualification, missing TBBEN/XFAILB pins and safety registers | Targeted at industrial embedded systems without automotive qualification or safety mandates | Choose for cost-sensitive industrial designs where AEC-Q100 Grade 2 and extended temp range suffice |
Compared with MPF5023CMBA0ES, MPF5023CMMA0ES omits safety-critical firmware and hardware blocks (e.g., triple self-test, fail-safe lock), while PF5023CVNA0ES removes automotive qualification entirely - making MPF5023CMBA0ES the sole option for ASIL B–compliant infotainment and ADAS power delivery.

FAQ
What is the operating temperature range for MPF5023CMBA0ES?
MPF5023CMBA0ES operates from −40 °C to +125 °C ambient temperature, meeting AEC-Q100 Grade 2 requirements for automotive under-hood and cockpit applications. Its thermal design supports continuous operation at maximum junction temperature (150 °C) with proper PCB layout and heatsinking via the exposed pad.
Does MPF5023CMBA0ES support dynamic voltage scaling (DVS)?
Yes, MPF5023CMBA0ES supports real-time dynamic voltage scaling via its 3.4 MHz I²C interface. Each buck regulator's output voltage can be adjusted in 6.25 mV steps during system operation - enabling precise coordination with processor performance states and optimizing power efficiency in MPF5023CMBA0ES-based designs.
How does the ASIL B safety architecture manifest in MPF5023CMBA0ES?
MPF5023CMBA0ES implements ASIL B compliance through hardware-enforced self-tests (bandgap matching, register CRC, oscillator tolerance), fail-safe state locking on critical faults, dedicated safety pins (XFAILB, TBBEN), and safety-critical register protection. These features are absent in non-ASIL variants like MPF5023CMMA0ES and MPF5023CVNA0ES.
Can MPF5023CMBA0ES be used without OTP programming?
Yes, MPF5023CMBA0ES operates with hardwired defaults if OTP is unprogrammed, but full functionality - including custom sequencing, voltage settings, and safety configurations - requires OTP programming by NXP or authorized partners. Customer OTP programming is restricted to engineering evaluation using NXP's GUI and socketed EVB.
What package type and thermal characteristics apply to MPF5023CMBA0ES?
MPF5023CMBA0ES uses a 40-pin HVQFN package (6 mm × 6 mm × 0.9 mm, 0.5 mm pitch) with wettable flank and exposed thermal pad. Its thermal resistance is RθJA = 26.8 °C/W (2s6p board), enabling >3 W power dissipation with standard 4-layer PCB layout and adequate thermal vias under the EPAD.
