Product details
Overview
MPF5024AMBA0ESR2 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, one-time programmable (OTP) configuration memory, and 3.4 MHz I²C interface - designed for i.MX 8/S32V application processors in infotainment systems.
For engineers reviewing the MPF5024AMBA0ESR2 datasheet, MPF5024AMBA0ESR2 pinout, MPF5024AMBA0ESR2 application, or MPF5024AMBA0ESR2 equivalent, this page delivers verified regulator specs, safety-critical monitoring features, thermal shutdown behavior, QFN40 wettable flank package details, and confirmed ASIL B functional safety implementation per ISO 26262.
Technical Context
The MPF5024AMBA0ESR2 implements a deterministic state machine supporting fail-safe transitions, self-test routines (up to 3 attempts), and configurable power-up sequencing via OTP or runtime I²C. It integrates independent voltage monitors, ABIST, CRC-protected register loading, and dual bandgap references for ASIL B fault detection.
Its clock architecture supports 20 MHz internal oscillator, 100 kHz reference, external SYNC input/output, spread-spectrum modulation, and manual frequency tuning - all synchronized across four buck stages. Thermal protection triggers at 150 °C junction temperature with latch-up immunity up to 100 mA.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPF5024CMBA0ESR2 | Same die, automotive ASIL B grade, but rated for 125 °C ambient (vs. 105 °C for MPF5024AMBA0ESR2) | Required for under-hood or high-ambient engine bay deployments; identical pinout and firmware compatibility | Select when operating ambient exceeds 105 °C or full AEC-Q100 Grade 0 qualification is mandated |
| MPF5024CVNA0ESR2 | Industrial-grade variant (105 °C ambient), no ASIL B safety features (no ABIST, no self-test, no fail-safe state logic) | Suitable for non-automotive embedded systems where functional safety is not required | Choose only for cost-sensitive industrial designs without ISO 26262 requirements; not drop-in replaceable due to missing safety registers |
Compared with MPF5024AMBA0ESR2, MPF5024CMBA0ESR2 extends thermal capability for harsher environments while retaining full ASIL B functionality, whereas MPF5024CVNA0ESR2 removes safety logic entirely - making it unsuitable for automotive use despite identical packaging and regulator specs.

FAQ
What is the maximum input voltage rating for MPF5024AMBA0ESR2?
The MPF5024AMBA0ESR2 has an absolute maximum VIN rating of 6.0 V, but sustained operation above 5.5 V is limited to ≤1800 seconds over the device lifetime to ensure reliability. The recommended operating range is 2.7 V to 5.5 V, with UVDET threshold set at 2.7 V for power-on reset initiation.
Does MPF5024AMBA0ESR2 support dynamic voltage scaling (DVS)?
Yes, MPF5024AMBA0ESR2 supports runtime DVS via its 3.4 MHz I²C interface. Each buck regulator (SW1–SW4) can be reconfigured on-the-fly between 0.4 V and 1.8 V in 6.25 mV steps, enabling adaptive power management aligned with processor performance states.
Is MPF5024AMBA0ESR2 pin-compatible with other PF5024 variants?
Yes, MPF5024AMBA0ESR2 shares identical HVQFN40 pinout and footprint with MPF5024CMBA0ESR2 and MPF5024CVNA0ESR2. However, ASIL B safety features (ABIST, self-test, fail-safe logic) are only active in the A- and C-suffix variants - software register maps differ accordingly.
How does the OTP memory in MPF5024AMBA0ESR2 function?
The OTP memory in MPF5024AMBA0ESR2 stores startup configurations including output voltages, sequencing order, soft-start timing, and safety thresholds. It is programmed exclusively by NXP or authorized partners during manufacturing - customer OTP programming is prohibited for production units per datasheet Rev. 3.2.
What thermal performance can be expected from MPF5024AMBA0ESR2 in a standard PCB layout?
With a JEDEC JESD51-7 2s6p test board (4 internal layers, 3×3 thermal vias under EPAD), MPF5024AMBA0ESR2 achieves RθJA = 26.8 °C/W and ΨJB = 12.3 °C/W. This enables full 2.5 A per buck channel operation at 105 °C ambient with proper copper area and airflow.
