Product details
Overview
MPF5024CMMA0ESR2 from NXP Semiconductors is an automotive-grade QM-safety power management IC (PMIC) integrating four high-efficiency buck regulators (0.4 V–1.8 V, 2.5 A each), I²C-configurable sequencing, OTP-stored startup configuration, and ASIL B-compatible monitoring circuitry. It serves as a primary PMIC for i.MX 8/S32V application processors in infotainment systems requiring precise voltage rail control and robust fault handling.
For engineers reviewing the MPF5024CMMA0ESR2 datasheet, MPF5024CMMA0ESR2 pinout, MPF5024CMMA0ESR2 application, or MPF5024CMMA0ESR2 equivalent, this device delivers deterministic power-up sequencing, spread-spectrum switching noise reduction, watchdog supervision, and fail-safe state transitions - all within a 40-pin HVQFN package with wettable flanks for automotive-grade solder joint reliability.
Technical Context
The MPF5024CMMA0ESR2 implements a hierarchical state machine supporting LP_Off, QPU_Off, self-test (ASIL B variant only), power-up sequencing, Run, Standby, and Fail-Safe states - with configurable transitions via OTP bits and real-time I²C control. Its digital core includes CRC-protected register mirroring, ABIST-enabled analog monitoring, and programmable thermal/UV/OV/ILIM fault detection.
Each of the four buck regulators supports dynamic voltage scaling, multiphase operation, VTT termination (SW2), and independent enable/PGOOD signaling. Clock synchronization is handled via the SYNC pin (bidirectional), while 3.4 MHz I²C enables runtime tuning of output voltages, soft-start timing, and protection thresholds without external components.

FAQ
What is the operating temperature range for MPF5024CMMA0ESR2?
MPF5024CMMA0ESR2 is qualified for automotive use with an ambient operating temperature range of −40 °C to +125 °C. This rating is confirmed in Table 5 of the official datasheet (Rev. 3.2, March 2024) and aligns with AEC-Q100 Grade 1 requirements. Junction temperature is specified up to 150 °C, and thermal resistance values (e.g., RθJA = 26.8 °C/W) assume JEDEC JESD51-7 2s6p board conditions.
Does MPF5024CMMA0ESR2 support dynamic voltage scaling (DVS)?
Yes, MPF5024CMMA0ESR2 supports dynamic voltage scaling on all four buck regulators (SW1–SW4). Each regulator's output voltage can be adjusted in 6.25 mV steps from 0.4 V to 1.8 V via I²C writes to the corresponding VSWx_RUN[7:0] register. DVS is enabled during Run state and allows real-time adaptation to processor load states without hardware changes.
How does the OTP memory in MPF5024CMMA0ESR2 function?
The OTP memory in MPF5024CMMA0ESR2 stores default configurations including output voltages, power-up sequencing order, soft-start timing, and safety-related bits. It is programmed exclusively by NXP or authorized partners during manufacturing. Customer OTP emulation is permitted only on evaluation boards during engineering development - not for production units - as stated in Section 4 of the datasheet.
Can MPF5024CMMA0ESR2 be used in ASIL B–compliant systems?
No, MPF5024CMMA0ESR2 is rated for QM (Quality Management) safety level only. For ASIL B compliance, the MPF5024CMBA0ESR2 variant must be used - it includes additional safety mechanisms such as fail-safe state logic, ABIST-enforced self-tests, secure I²C writes, and dedicated fault flags (e.g., AB_SWx_OV, STEST_NOK) absent in MPF5024CMMA0ESR2.
What package type and mounting features does MPF5024CMMA0ESR2 use?
MPF5024CMMA0ESR2 uses a 40-pin HVQFN package (SOT618-17(D)), measuring 6 mm × 6 mm × 0.9 mm with 0.5 mm pitch and wettable flank geometry. The exposed pad (EPAD) must be soldered to PCB ground for thermal dissipation and EMI control. Wettable flanks enable automated optical inspection (AOI) of solder joints - a key requirement for automotive manufacturing traceability.
