Product details
Overview
MPF5020CMMACES from NXP Semiconductors is a safety-qualified power management IC (PMIC) designed as the primary power solution for i.MX RT1170 applications, integrating three 2.5 A buck regulators (SW1/SW2/SWND1), one 400 mA LDO with load switch option, RTC supply (VSNVS), watchdog timer, and ASIL B–capable monitoring circuitry. It operates in standalone or companion PMIC mode with OTP-configurable startup and high-speed I²C reconfiguration.
For engineers reviewing the MPF5020CMMACES datasheet, MPF5020CMMACES pinout, MPF5020CMMACES application, or MPF5020CMMACES equivalent, this device delivers automotive-grade power sequencing, dynamic voltage scaling, VTT termination support, and fail-safe state transitions - critical for infotainment and real-time MCU systems requiring functional safety compliance and thermal robustness up to 125 °C.
Technical Context
The MPF5020CMMACES implements a deterministic state machine with LP_Off → QPU_Off → self-test (ASIL B only) → power-up sequencing, enabling seamless interface with i.MX RT1170 processors. Its architecture supports dual-phase configuration for SW1/SW2, VTT mode on SW2, and programmable soft-start/power-down sequences stored in OTP memory.
It features 3.4 MHz I²C communication with CRC protection, independent PGOOD outputs per regulator plus global PGOOD, and integrated ABIST for analog monitor validation. Thermal shutdown triggers at 150 °C junction temperature, and fault handling includes watchdog event counting, fault timer expiration, and XFAILB-driven fail-safe transition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Main input voltage (VIN) | 4.5 V to 5.5 V operating range; UVLO detection at 4.5 V ensures stable startup under automotive battery transients. |
| Buck regulator output range | SW1/SW2: 0.4 V–1.8 V (6.25 mV step); SWND1: 1.0 V–4.1 V - enables core, I/O, and peripheral rail flexibility for i.MX RT1170. |
| Output current rating | 2500 mA per buck regulator; supports high-current CPU cores and DDR interfaces without external boost stages. |
| LDO1 output | 1.5 V–5.0 V, 400 mA with optional load switch - configurable for always-on or controlled power domains. |
| VSNVS supply | 1.8 V / 3.0 V / 3.3 V, 10 mA RTC backup - maintains real-time clock during main power loss with coin-cell charging capability. |
| I²C interface speed | Up to 3.4 MHz - enables fast runtime reconfiguration of voltage, sequencing, and safety registers during system operation. |
| Operating temperature | −40 °C to +125 °C ambient - qualified for automotive cabin and industrial edge environments. |
Pinout & Package
MPF5020CMMACES uses a 40-pin HVQFN package (6 mm × 6 mm × 0.9 mm, 0.5 mm pitch) with wettable flank and exposed thermal pad (EPAD) connected to ground for enhanced thermal dissipation in high-power density layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1FB, SW2FB, SWND1FB | Buck feedback inputs | Enable precise closed-loop regulation; support external resistor dividers for programmable output voltages. |
| EN1, EN2, EN3, EN4 | Independent enable inputs | Allow hardware-controlled sequencing or MCU-gated activation of each regulator/LDO without I²C dependency. |
| PGOOD1–PGOOD4, PGOOD | Per-regulator and global power-good signals | Provide synchronous status indication for system boot validation and fault isolation in safety-critical paths. |
| RESETBMCU | Open-drain reset output | Drives i.MX RT1170 reset line; released after successful power-up sequence completion per OTP configuration. |
| V1P5A / V1P5D | Internal analog/digital 1.5 V supplies | Power internal PMIC logic blocks; decoupled rails minimize noise coupling between analog and digital subsystems. |
| INTB | Interrupt open-drain output | Signals faults (OV/UV/thermal/watchdog) to host MCU; active-low assertion simplifies level-shifting in mixed-voltage systems. |
| XFAILB | Fail-safe trigger input/output | Initiates fail-safe state transition when pulled low; used for external system-level failure coordination in ASIL B designs. |
| VDDOTP | OTP programming supply | Requires 1.8 V–10 V input; enables secure OTP configuration loading during engineering development via NXP GUI tools. |
Key Features
| Feature | Design Value |
|---|---|
| One-time programmable (OTP) memory | Stores startup voltage, sequencing order, and safety configuration - eliminates external resistors and reduces BOM count by up to 12 components. |
| Dual-phase and VTT modes | SW1/SW2 can be combined into single 5 A phase or configured as VTT terminator - supports DDR4/DDR5 memory termination requirements directly. |
| Functional safety monitoring | Meets ASIL B requirements via independent voltage/thermal/watchdog monitoring, ABIST, CRC-protected registers, and fail-safe state lock-down. |
| Thermal resistance (RθJA) | 26.8 °C/W (2s6p board) - enables >2 W continuous power dissipation with standard 4-layer PCB and thermal vias under 125 °C ambient. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPF5020CMBA0ES | ASIL B safety grade; includes additional ABIST, FS_CNT, and secure I²C registers not present in MPF5020CMMACES (QM grade). | Required for full ISO 26262 ASIL B system certification; MPF5020CMMACES lacks fail-safe counter and secure write enable bits. | Select MPF5020CMBA0ES when end-equipment requires certified functional safety beyond QM level - e.g., ADAS camera ECU or central domain controller. |
| MPF5020CVNA0ES | Industrial temperature grade (−40 °C to +105 °C); same QM safety level but lower max ambient rating than MPF5020CMMACES (125 °C). | Suitable for non-automotive embedded systems where extended temperature range is unnecessary - e.g., network routers or test equipment. | Choose MPF5020CVNA0ES for cost-sensitive industrial designs without automotive thermal or safety requirements. |
Compared with MPF5020CMMACES, MPF5020CMBA0ES adds ASIL B–specific safety mechanisms at higher cost and complexity, while MPF5020CVNA0ES trades 20 °C thermal margin for broader commercial availability - making MPF5020CMMACES the optimal balance of automotive qualification, i.MX RT1170 reference compatibility, and production scalability.

FAQ
What is the primary application target for MPF5020CMMACES?
The MPF5020CMMACES is explicitly designated as the IMX RT1170 Reference part per NXP's ordering documentation. It delivers optimized power sequencing, dynamic voltage scaling, and safety monitoring tailored for the i.MX RT1170 crossover MCU - supporting its dual-core architecture, DDR interface, and real-time deterministic operation in automotive and industrial edge applications.
Does MPF5020CMMACES support ASIL B functional safety?
No - MPF5020CMMACES is rated QM (Quality Management) per NXP's ordering table, distinguishing it from the ASIL B–qualified MPF5020CMBA0ES variant. While it includes monitoring circuits and watchdog functionality, it lacks the fail-safe counter (FS_CNT), secure I²C write enable, and ABIST coverage required for ASIL B certification. For ASIL B systems, MPF5020CMBA0ES must be selected.
How does the OTP configuration work on MPF5020CMMACES?
MPF5020CMMACES uses on-chip one-time programmable memory to store startup voltage levels, power-up/down sequencing order, and default register states. OTP programming is performed exclusively by NXP or authorized partners during manufacturing; customers may emulate and verify configurations using NXP's GUI and socketed evaluation board during engineering development, but production programming is prohibited.
What package type and thermal characteristics does MPF5020CMMACES use?
MPF5020CMMACES 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 junction-to-ambient thermal resistance is 26.8 °C/W on a 2s6p PCB, enabling reliable operation at 125 °C ambient with proper thermal via placement - validated per JEDEC JESD51-7 standards.
Can MPF5020CMMACES operate as a standalone PMIC without a host processor?
Yes - MPF5020CMMACES supports fully autonomous operation using OTP-stored configuration. It performs complete power-up sequencing, fault monitoring, and state transitions (including LP_Off, QPU_Off, and System ON) without I²C intervention. The host processor is only required for runtime reconfiguration, advanced diagnostics, or dynamic voltage scaling adjustments.
