Product details
Overview
MPF5024CMBA0ES 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 certification, OTP-configurable startup sequencing, and 3.4 MHz I²C interface. It serves as a primary PMIC for i.MX 8/S32V application processors in infotainment systems requiring precise voltage rail control and functional safety.
For engineers reviewing the MPF5024CMBA0ES datasheet, MPF5024CMBA0ES pinout, MPF5024CMBA0ES application, or MPF5024CMBA0ES equivalent, this device delivers deterministic power-up sequencing, real-time fault monitoring (OV/UV/thermal/ABIST), watchdog supervision, and configurable spread-spectrum switching - all within a 40-pin HVQFN package qualified for 125 °C ambient operation.
Technical Context
The MPF5024CMBA0ES implements a safety-critical state machine supporting ASIL B compliance, including triple self-test execution on bandgap matching, oscillator tolerance (±15%), mirror register CRC integrity, and analog built-in self-test (ABIST). Its OTP memory stores default regulator voltages, enable sequences, soft-start timing, and fail-safe thresholds.
Each of the four buck regulators supports dynamic voltage scaling, programmable current limit, VTT termination mode (SW2), and independent PGOOD outputs plus global PGOOD. The 3.4 MHz I²C interface enables runtime reconfiguration of output voltages, switching frequency tuning, and safety register access under secure write protocol.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPF5024CMMA0ES | Same silicon, QM (Quality Management) grade - lacks ASIL B self-test, XFAILB, FS_CNT, and secure I²C features | Approved for non-safety-critical automotive modules (e.g., telematics, body control) but not infotainment or ADAS | Select when functional safety certification is not required and cost optimization is prioritized. |

FAQ
What safety certifications does the MPF5024CMBA0ES hold?
The MPF5024CMBA0ES is certified to ASIL B per ISO 26262, with integrated functional safety features including triple self-test execution, analog built-in self-test (ABIST), mirror register CRC verification, XFAILB fail-safe pin, and fault counters. It meets AEC-Q100 Grade 0 (−40 °C to +125 °C) and supports fail-safe state transitions triggered by thermal, voltage, or watchdog faults. MPF5024CMBA0ES implements these capabilities in hardware without requiring external safety monitors.
Can the MPF5024CMBA0ES be used with non-NXP processors?
Yes, the MPF5024CMBA0ES supports non-NXP processors requiring multi-rail power with precise sequencing and monitoring. Its four buck regulators (0.4 V–1.8 V, 2.5 A), 3.4 MHz I²C interface, and programmable enable/PGOOD logic allow integration with ARM-based SoCs, FPGAs, or DSPs. MPF5024CMBA0ES has been validated for use with i.MX 6 series and several third-party processors, provided input voltage and sequencing requirements align with its OTP-configurable architecture.
How is OTP programming performed for the MPF5024CMBA0ES?
OTP programming for MPF5024CMBA0ES is performed exclusively by NXP or NXP-authorized third parties during production - customers may only perform OTP emulation and development programming using NXP's GUI and socketed evaluation board. Programming requires VDDOTP = 5 V–10 V and follows strict protocols to prevent corruption; once programmed, OTP contents (voltage targets, sequencing, safety thresholds) are immutable. MPF5024CMBA0ES supports post-OTP runtime tuning via I²C for non-OTP parameters like DVS and frequency.
Does the MPF5024CMBA0ES support spread-spectrum switching?
Yes, the MPF5024CMBA0ES supports spread-spectrum modulation on all four buck regulators to reduce peak EMI emissions. This feature is programmable via I²C registers and operates alongside manual frequency tuning and external clock synchronization through the SYNC pin. Spread-spectrum helps MPF5024CMBA0ES meet CISPR-32 Class B conducted emission limits in space-constrained automotive PCBs without adding ferrite beads or extra filtering components.
What is the role of the XFAILB pin on the MPF5024CMBA0ES?
The XFAILB pin on MPF5024CMBA0ES is a bidirectional fail-safe I/O that signals critical system faults. When asserted low, it forces the PMIC into a fail-safe state (FS_CNT increment, regulators disabled, RESETBMCU held active), enabling external controllers to initiate safe shutdown or limp-home operation. XFAILB is monitored during self-test and fault conditions; its behavior is configurable via OTP_FS_BYPASS and OTP_XFAILB_EN. MPF5024CMBA0ES uses XFAILB as a hardware-level safety mechanism independent of I²C communication.
