Product details
Overview
MC33VR5500V1ESR2 from NXP Semiconductors is an AEC-Q100 Grade 1 automotive high-voltage PMIC for radio, V2X, and infotainment systems. It integrates a 60 V input VPRE synchronous buck controller (up to 10 A peak), three low-voltage synchronous buck converters (BUCK1–BUCK3, each up to 3.6 A peak), a BOOST converter (1.5 A peak), and two LDOs (400 mA each), all with I²C control and power sequencing via OTP configuration.
For engineers reviewing the MC33VR5500V1ESR2 datasheet, MC33VR5500V1ESR2 pinout, MC33VR5500V1ESR2 application, or MC33VR5500V1ESR2 equivalent, key selection considerations include its 60 V max input rating, multi-rail sequencing capability across seven configurable slots, EMC-optimized frequency synchronization (FIN/FOUT), and fail-safe voltage monitoring with PGOOD/RSTB outputs.
Technical Context
The VR5500 architecture separates power management into a main state machine (handling Normal_M, Standby, and OFF modes) and a fail-safe state machine (independent monitoring of VBOS, VPRE, and regulator faults). Power-up sequencing starts with VPRE, then BOOST, followed by OTP-configured regulators across seven time-slotted stages (250 µs or 1 ms spacing).
Regulator control includes static voltage scaling (SVS) on BUCK1 for MCU core supply, multi-phase operation between BUCK1 and BUCK2 (7.2 A peak combined), and external current-sense feedback for VPRE. All critical functions-wake-up detection (WAKE1/WAKE2), thermal shutdown, overvoltage/undervoltage monitoring, and interrupt generation-are hardware-asserted with configurable I²C masking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage automotive PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPQ4333-AEC1 | Single 60 V input buck (3.5 A), no integrated LDOs or multi-rail sequencing; lacks I²C, PSYNC, or fail-safe state machine. | Targeted at simpler single-load applications (e.g., camera module supply); not suitable for radio/infotainment SoC power trees. | Select when only one high-voltage buck rail is needed and cost/space constraints preclude multi-output integration. |
| TPS659413-Q1 | 4-channel buck + 3 LDO PMIC; max 20 V input; no VPRE controller; uses SPI instead of I²C; no external MOSFET drive capability. | Designed for ADAS domain controllers (e.g., radar, vision SoCs); insufficient for 24 V battery-fed radio front-ends requiring >40 V operation. | Prefer for lower-input-voltage ADAS subsystems where SPI interface and smaller footprint are prioritized over 60 V robustness and VPRE flexibility. |
Compared with MPQ4333-AEC1 and TPS659413-Q1, MC33VR5500V1ESR2 uniquely combines 60 V input tolerance, external VPRE controller scalability, seven-slot OTP sequencing, and dual-state-machine safety-making it the only option qualified for full-featured automotive radio and V2X power delivery where load dump resilience and fail-safe monitoring are mandatory.

FAQ
What is the primary function of the PSYNC pin on the MC33VR5500V1ESR2?
The PSYNC pin (Pin 38) provides bidirectional power synchronization between the MC33VR5500V1ESR2 and another VR5500 device or external PMIC. When pulled up to VBOS, it acts as a master to coordinate startup sequencing-halting before or after VPRE activation until the slave device signals readiness. This ensures deterministic, glitch-free power-up across multi-PMIC systems in complex automotive ECUs.
How does the MC33VR5500V1ESR2 support ultra-low-power vehicle keep-alive states?
The MC33VR5500V1ESR2 achieves 10 µA typical quiescent current in OFF mode (TA < 85 °C) by disabling all regulators except VBOS, shutting down internal clocks and digital logic, and retaining only WAKE1/WAKE2 detection circuitry. This enables extended battery life during parked conditions while maintaining instant wake-up response-critical for telematics and remote keyless entry subsystems.
Can the MC33VR5500V1ESR2 be used without programming its OTP memory?
Yes-the MC33VR5500V1ESR2 ships with factory-default OTP configuration (V1 variant corresponds to Radio Mercury reference design). While full customization requires OTP programming via DBG pin and NXP FlexGUI, the device operates immediately with pre-configured sequencing, default voltages, and safety thresholds. Engineering teams may use OTP emulation in debug mode to validate settings before final production programming.
What distinguishes the fail-safe state machine from the main state machine in the MC33VR5500V1ESR2?
The fail-safe state machine in the MC33VR5500V1ESR2 operates independently of the main state machine and monitors VBOS, VPRE, and regulator OV/UV conditions using dedicated analog comparators and latches. It asserts RSTB and PGOOD without software intervention-even if the main logic is stalled or corrupted-ensuring deterministic fault response required for ASIL-B/C automotive systems.
Does the MC33VR5500V1ESR2 support dynamic voltage scaling for MCU core supply?
Yes-the MC33VR5500V1ESR2's BUCK1 converter (dedicated to MCU core) supports Static Voltage Scaling (SVS) via I²C register writes to M_REG_CTRL2. This allows real-time adjustment of output voltage (e.g., 1.2 V → 0.9 V) during low-activity states to reduce dynamic power consumption, with hardware-enforced slew rate limiting to prevent supply droop during transitions.
