Product details
Overview
MC33VR5500V1KSR2 from NXP Semiconductors is an AEC-Q100 Grade 1 automotive high-voltage PMIC with six regulated outputs: one external VPRE buck controller (60 V max input), three integrated synchronous buck converters (BUCK1–BUCK3, up to 3.6 A each), one boost converter (1.5 A peak), and two LDOs (400 mA each). It supports I²C configuration, power sequencing via OTP, and operates in radio, V2X, and infotainment systems.
For engineers reviewing the MC33VR5500V1KSR2 datasheet, MC33VR5500V1KSR2 pinout, MC33VR5500V1KSR2 application, or MC33VR5500V1KSR2 equivalent, key selection criteria include its 60 V input rating, multi-phase BUCK1+BUCK2 capability (7.2 A peak), OFF-mode sleep current (10 μA typ), EMC-optimized frequency synchronization (FIN/FOUT), and AEC-Q100 qualification for under-hood automotive use.
Technical Context
The MC33VR5500V1KSR2 integrates dual state machines: a main power management state machine handling startup, sequencing, and I²C control, and a fail-safe state machine independently monitoring VBOS, VPRE, and regulator faults to assert RSTB/PGOOD. Power-up begins with VPRE (external buck controller), followed by BOOST, then sequenced BUCK/LDO rails per OTP-defined slots (250 µs or 1 ms inter-slot delay).
It implements hardware-level safety features including three voltage monitors, thermal shutdown detection per regulator, wake-up inputs (WAKE1/WAKE2) with configurable thresholds, and deep fail-safe (DEEP-FS) mode triggered by VPRE feedback overvoltage or TSD events. Configuration is stored in one-time-programmable (OTP) memory, with engineering-mode debug access via DBG pin and fixed I²C address 0x20.

Pinout & Package
MC33VR5500V1KSR2 is housed in a thermally enhanced HPQFN56 (SOT684-23) package with wettable flanks and exposed thermal pad (EP) connected to GND. The 56-pin layout supports high-current paths (VPRE, BUCKx_SW), analog monitoring (VMON1, VCOREMON), I²C (SCL/SDA), and system coordination (PSYNC, FIN/FOUT).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSUP1 / VSUP2 | Main high-voltage supply inputs | Accept 60 V DC; require external reverse-battery diodes; enable operation in 12 V/24 V automotive systems. |
| VPRE_SW / PRE_GHS / PRE_GLS | VPRE gate drive and switching node | Drive external high-side/low-side MOSFETs; support up to 10 A peak output with programmable frequency. |
| BUCK1_SW / BUCK2_SW / BUCK3_SW | Integrated buck switching nodes | Direct connection points for external inductors; each supports up to 3.6 A peak; BUCK1/BUCK2 share phase control for multi-phase operation. |

| SCL / SDA | I²C serial interface | Enable real-time configuration, monitoring, and fault reporting; support CRC-protected transactions and debug-mode OTP emulation. |
| PSYNC | Power synchronization I/O | Coordinate startup/shutdown timing with second VR5500 or external PMIC; eliminates sequencing mismatches in multi-PMIC designs. |
| WAKE1 / WAKE2 | Dual wake-up inputs | Asynchronous interrupt sources; support global wake-up with external series resistor; trigger exit from Standby or OFF mode. |
| EP (exposed pad) | Thermal and electrical ground reference | Internally connects BUCK1/BUCK2/BUCK3 low-side switches to GND; must be soldered to PCB ground plane for thermal and EMI performance. |

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 |
|---|---|---|---|
| MPQ4436-AEC1 | Single 3.5 A synchronous buck (40 V max); no integrated LDOs, multi-phase, or fail-safe state machine. | Limited to single-rail core supply; lacks OTP sequencing, voltage monitoring, and AEC-Q100 fail-safe architecture. | Choose when only one high-current rail is needed and system-level safety is handled externally. |
| TPS659413-Q1 | 6-rail PMIC (3 buck + 3 LDO); 36 V max input; no external buck controller; no PSYNC or FIN/FOUT synchronization. | Supports ADAS SoCs but lacks VPRE-level flexibility and load-dump robustness beyond 36 V. | Prefer for TI ecosystem designs where 36 V operation suffices and multi-PMIC synchronization is not required. |

Does MC33VR5500V1KSR2 support multi-phase operation between BUCK1 and BUCK2?
Yes, MC33VR5500V1KSR2 supports true multi-phase operation between BUCK1 and BUCK2. When configured via OTP, they operate interleaved with 180° phase shift, enabling combined peak current delivery up to 7.2 A on a single output rail-ideal for high-performance MCU core supplies requiring dynamic current bursts.
How is power sequencing controlled on MC33VR5500V1KSR2?
Power sequencing on MC33VR5500V1KSR2 is controlled by one-time-programmable (OTP) memory defining seven configurable slots. Each slot assigns BUCK1–BUCK3, LDO1, LDO2, or BOOST to a specific startup order with 250 µs or 1 ms inter-slot delay-enabling precise ramp-up timing for DDR, peripherals, and analog subsystems without external logic.
What safety features does MC33VR5500V1KSR2 provide for automotive applications?
MC33VR5500V1KSR2 includes a dedicated fail-safe state machine with independent voltage monitoring (VBOS, VPRE), thermal shutdown detection per regulator, and hardware-driven assertion of PGOOD/RSTB outputs. It meets AEC-Q100 Rev H Grade 1 requirements and supports DEEP-FS mode for critical fault containment-no MCU intervention required.
Can MC33VR5500V1KSR2 synchronize switching frequency with other PMICs?
Yes, MC33VR5500V1KSR2 provides bidirectional frequency synchronization via FIN (input) and FOUT (output) pins, and supports multi-PMIC coordination through the PSYNC pin.
