Product details
Overview
MC33VR5500V1KS 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), one boost converter (1.5 A peak), and two LDOs (400 mA DC). Its I²C interface, power-good/reset outputs, and dual wake-up inputs enable robust MCU-supply sequencing in 12 V/24 V vehicle architectures.
For engineers reviewing the MC33VR5500V1KS datasheet, MC33VR5500V1KS pinout, MC33VR5500V1KS application, or MC33VR5500V1KS equivalent, key selection criteria include its 60 V max input rating, OTP-programmable power-up sequencing across seven slots, spread-spectrum and frequency synchronization for EMC optimization, and support for multi-phase BUCK1+BUCK2 operation up to 7.2 A peak on a single rail.
Technical Context
The MC33VR5500V1KS implements a dual-state-machine architecture: a main state machine manages regulator sequencing, standby transitions, and I²C-controlled power states, while a fail-safe state machine independently monitors VBOS, VPRE, and voltage rails to assert RSTB and PGOOD on fault detection. Power-up begins with VPRE, followed by BOOST, then proceeds through seven OTP-configurable slots for BUCK1/BUCK2/BUCK3/LDO1/LDO2.
It supports external frequency synchronization via FIN/FOUT pins, manual frequency tuning, and spread-spectrum modulation to reduce EMI. The device features static voltage scaling (SVS) on BUCK1 and BUCK2, multi-phase capability between BUCK1 and BUCK2, and configurable thermal shutdown response per regulator via OTP bits (OTP_conf_tsd[5:0]).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Input Voltage | 60 V DC - supports 12 V and 24 V automotive battery systems including jump-start (48 V/15 min) and load dump (58 V) without external protection. |
| VPRE Controller Output | Configurable output; drives external MOSFETs; supports up to 10 A peak current - enables flexible high-power pre-regulation for downstream SMPS. |
| BUCK1 Core Supply | Synchronous buck with SVS; 3.6 A peak; dedicated to MCU core supply - provides dynamic voltage scaling for performance/power trade-offs. |

| AEC-Q100 Qualification | Grade 1 (−40 °C to +125 °C ambient), MSL3 - certified for under-hood and infotainment module deployment. |
Pinout & Package
MC33VR5500V1KS is housed in a thermally enhanced HPQFN56 (SOT684-23) package with wettable flanks and an exposed thermal pad (EP) connected to internal GND planes of BUCK1/BUCK2/BUCK3 low-side switches.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSUP1 / VSUP2 | Main HV input supply | Accepts 60 V DC input; requires external reverse-battery diode; powers VPRE controller and internal bias. |
| VPRE_SW / PRE_GHS / PRE_GLS | VPRE gate drive & switching node | Drives external high-side/low-side MOSFETs; SW node connects to external inductor; supports programmable switching frequency. |
| BUCK1_SW / BUCK2_SW / BUCK3_SW | Integrated buck switching nodes | Direct connection points to external inductors; each supports synchronous rectification and soft-start control. |
| PGOOD / RSTB | Power-good and reset outputs | Active-low open-drain outputs; require external pull-up to VDDIO; signal system readiness and initiate MCU reset on fault. |
| SCL / SDA | I²C communication interface | Supports standard/fast-mode I²C; includes CRC validation; used for OTP programming, runtime configuration, and fault logging. |
| WAKE1 / WAKE2 | Dual wake-up inputs | Asynchronous wake sources; accept 60 V tolerant signals; require external series resistor when used as global wake pins. |
| PSYNC | Power synchronization I/O | Enables coordinated power-up/down with second VR5500 or external PMIC; supports master/slave configuration via OTP. |
| AMUX | Analog multiplexed output | Delivers selectable analog monitoring signals (e.g., VCOREMON, VMON1) to MCU ADC via I²C command. |
Key Features
| Feature | Design Value |
|---|---|
| OTP-based power sequencing | Seven configurable startup slots with 250 µs or 1 ms inter-slot delay - enables precise timing alignment for mixed-voltage SoCs and memory subsystems. |
| EMC-optimized switching | Frequency synchronization (FIN/FOUT), spread spectrum, and slew rate control - reduces peak EMI amplitude for CISPR 25 Class 5 compliance. |
| Fail-safe voltage supervision | Independent monitoring of VBOS, VPRE, and three analog inputs (VMON1, VCOREMON, VBOOST) - triggers autonomous RSTB/PGOOD assertion without MCU intervention. |
| Multi-phase BUCK1+BUCK2 operation | Phase-shifted interleaving up to 7.2 A peak on one rail - lowers output ripple, reduces inductor size, and improves thermal distribution. |
| Debug mode with OTP emulation | DBG pin entry (4.5–5.5 V) enables I²C-based OTP reconfiguration using NXP FlexGUI - accelerates firmware bring-up and hardware validation. |
| Thermal management | Per-regulator thermal shutdown configuration (OTP_conf_tsd) and junction temperature monitoring up to 150 °C - prevents damage during overload or poor heatsinking. |

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 |
|---|---|---|---|
| MPQ72951-AEC1 | Single-chip 6-output PMIC (no VPRE controller); max input 40 V; no multi-phase BUCK support; I²C + SPI interface. | Targeted at mid-tier infotainment with lower input voltage margin and no external high-side driver requirement. | Select when system uses integrated buck converters only and does not require 60 V tolerance or external MOSFET control. |
| TPS659413-Q1 | 13-rail PMIC with integrated 3.3 V/1.8 V/1.1 V bucks; max input 5.5 V; no HV input stage; supports ASIL-B functional safety. | Designed for domain controllers and ADAS SoCs where primary supply is already regulated to 5 V. | Select when upstream DC/DC provides stable 5 V input and ASIL-B diagnostics are required; not suitable as direct replacement for 12 V/24 V battery-fed designs. |
Compared with MPQ72951-AEC1 and TPS659413-Q1, the MC33VR5500V1KS uniquely combines 60 V input tolerance, a programmable VPRE controller for external FETs, and multi-phase BUCK capability-making it the only option among the three qualified for direct battery-connected radio and V2X modules requiring >40 V surge resilience and scalable current delivery.

FAQ
What is the maximum continuous operating voltage for MC33VR5500V1KS in automotive 24 V systems?
The MC33VR5500V1KS supports 36 V continuous operation when VPRE switches at 455 kHz, validated for 48 V jump-start (15 minutes) and 58 V load dump without external protection. At 2.2 MHz VPRE switching, max continuous voltage drops to 18 V. These ratings are defined in Section 11 of the datasheet and depend on VPRE configuration and thermal design.
How does MC33VR5500V1KS implement power sequencing across multiple rails?
The MC33VR5500V1KS uses OTP-programmable power sequencing across seven slots, with VPRE starting first, followed by BOOST, then BUCK1/BUCK2/BUCK3/LDO1/LDO2 assigned to slots 0–6. Slot delays are configurable to 250 µs or 1 ms. Sequencing is executed in reverse order during power-down, and PSYNC enables synchronization with external PMICs.
Can MC33VR5500V1KS operate in multi-phase mode with BUCK1 and BUCK2?
Yes, MC33VR5500V1KS supports interleaved multi-phase operation between BUCK1 and BUCK2, extending combined peak current capability to 7.2 A on a single rail. Phase offset and current balancing are managed internally; no external phase-control circuitry is required.
What wake-up sources are supported by MC33VR5500V1KS?
The MC33VR5500V1KS provides two dedicated wake-up inputs (WAKE1 and WAKE2), both 60 V tolerant and compatible with global wake schemes. Each requires an external series resistor when used as a system-wide wake pin. Wake events trigger exit from Standby or OFF mode and initiate controlled power-up sequencing.
Is debug mode supported on MC33VR5500V1KS, and how is it enabled?
Yes, MC33VR5500V1KS supports debug mode via the DBG pin. When DBG is held at 4.5–5.5 V after VSUP exceeds VSUP_UVH and a wake event occurs, the device enters debug mode with fixed I²C address 0x20. This enables OTP emulation, register inspection, and configuration updates using NXP FlexGUI and socket EVB tools during engineering development.
