Product details
Overview
MC33PF8100EAES from NXP Semiconductors is an automotive-grade 12-channel power management IC (PMIC) designed for LS1046A processors with DDR4 memory (VDDQ + VTT). It integrates seven high-efficiency buck converters (SW1–SW7), four linear regulators (LDO1–LDO4), RTC supply (VSNVS), coin cell charger, watchdog timer, and ASIL B-compliant monitoring circuitry. Its OTP memory stores startup configuration, reducing external components for voltage/sequence setup.
For engineers reviewing the MC33PF8100EAES datasheet, MC33PF8100EAES pinout, MC33PF8100EAES application, or MC33PF8100EAES equivalent, this page delivers verified technical context, validated pin functions, confirmed automotive safety features, and real-world use cases in LS1046A-based networking systems requiring DDR4 VDDQ/VTT regulation and fail-safe power sequencing.
Technical Context
The MC33PF8100EAES implements a deterministic state machine for fault-aware power-up/down sequencing, with programmable soft-start, power-down order, and PGOOD monitoring. Its 3.4 MHz I²C interface enables dynamic voltage scaling on SW1–SW6 and runtime reconfiguration of regulator parameters including output voltage, current limit, and switching frequency tuning.
It supports dual-phase (SW1/SW2, SW3/SW4, SW5/SW6), triple-phase (SW1/SW2/SW3), and quad-phase (SW1/SW2/SW3/SW4) configurations for high-current CPU cores, while SW6 operates in VTT termination mode for DDR4 memory buses. The integrated 24-channel analog multiplexer enables system-level diagnostics via external sensor inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Regulator Count | 7 buck converters (SW1–SW7) + 4 LDOs (LDO1–LDO4) + VSNVS RTC supply - fully integrated power tree for LS1046A DDR4 subsystems. |
| Buck Output Range | SW1–SW6: 0.4 V to 1.8 V (6.25 mV steps); SW7: 1.0 V to 4.1 V - covers core, I/O, and auxiliary rail requirements. |
| Current Rating | 2500 mA per buck channel; 400 mA per LDO - sufficient for LS1046A VDDQ (1.2 V @ ≤2 A) and VTT (0.6 V @ ≤1.5 A) loads. |
| I²C Interface | Up to 3.4 MHz operation - enables fast register access for dynamic voltage scaling and real-time fault response. |
| Safety Compliance | ASIL B monitoring circuit (voltage, thermal, watchdog, ABIST) - meets functional safety requirements for automotive networking applications. |
| Package | HVQFN56, 8 mm × 8 mm × 0.85 mm, 0.5 mm pitch, wettable flanks - optimized for thermal dissipation and automated optical inspection in automotive PCB assembly. |
| Operating Temp | −40 °C to +105 °C ambient - qualified for under-hood and gateway ECU environments. |
Pinout & Package
HVQFN56 package with exposed thermal pad (EPAD), 0.5 mm pitch, 8 mm × 8 mm body, 0.85 mm height, step-cut wettable flanks for solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 50) | Main input supply | Accepts 2.7 V to 5.5 V input; powers internal LDOs and buck controller circuitry - must be decoupled near package for stability. |
| SW1FB–SW7FB (Pins 2,3,12,13,30,31,38) | Buck feedback inputs | Resistive divider inputs for closed-loop output voltage regulation; support ±1.5 % (SW1–SW6) or ±2 % (SW7) accuracy. |
| SW1LX–SW7LX (Pins 5,6,9,10,33,34,36) | Switching node outputs | High-frequency switching nodes driving external inductors; require low-inductance layout to minimize voltage spikes (< −3.0 V transient tolerance). |
| LDO1OUT–LDO4OUT (Pins 15,18,25,28) | LDO regulated outputs | 1.5 V to 5.0 V, 400 mA each; configurable as load switches - used for peripherals, I/O rails, or always-on domains. |
| VSNVS (Pin 47) | RTC supply output | 1.8 V / 3.0 V / 3.3 V selectable, 10 mA - powers secure non-volatile memory and real-time clock during system standby. |
| SCL/SDA (Pins 55/56) | I²C interface | 3.4 MHz high-speed bus for configuration, monitoring, and DVS control - requires pull-ups to VDDIO (1.6 V–3.3 V). |
| PGOOD (Pin 42) | Power-good indicator | Open-drain output asserting when all enabled rails meet regulation tolerance - used for processor reset coordination and boot sequencing. |
| FSOB (Pin 29) | Failsafe output | ASIL B safety-critical signal indicating fault condition; asserts low during critical failures (thermal, UVLO, watchdog timeout). |
Key Features
| Feature | Design Value |
|---|---|

| VTT termination mode on SW6 | Directly supplies DDR4 VTT (0.6 V) with active termination, eliminating discrete VTT regulators and improving signal integrity on memory buses. |
| 24-channel analog multiplexer | Allows monitoring of external temperature sensors, battery voltages, or rail currents via single ADC input - simplifies system health diagnostics. |
| ASIL B functional safety architecture | Includes independent voltage monitors, thermal shutdown, watchdog with programmable timeout, ABIST, and CRC-protected registers - supports ISO 26262 compliance evidence. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PF8200DHES | ASIL B certified (vs. QM for MC33PF8100EAES); adds FSOB assertion logic, ABIST-on-demand, and secure I²C write protection. | Required for new automotive designs targeting ISO 26262 ASIL B certification; supports fail-safe state transitions not present in PF8100. | Select MC33PF8200DHES if functional safety certification is mandatory; MC33PF8100EAES suffices for QM-level applications with external safety supervision. |
| MPQ4572GQ-AEC1 | Single 2.5 A buck converter (no multi-rail integration); no OTP, no LDOs, no I²C, no safety monitoring - discrete replacement only. | Only suitable for replacing individual rails (e.g., VDDQ), not full PMIC functionality; requires external sequencing logic and monitoring circuitry. | Use MPQ4572GQ-AEC1 only for cost-sensitive, non-safety-critical upgrades where existing design already handles sequencing and monitoring. |
Compared with MC33PF8200DHES, MC33PF8100EAES offers identical power architecture and pin compatibility but omits ASIL B-specific safety logic and secure registers - making it ideal for QM-tier LS1046A gateways where safety is managed at system level. Versus MPQ4572GQ-AEC1, it provides complete 12-channel integration, eliminating 11+ discrete regulators and associated timing complexity.

FAQ
What is the primary target processor for MC33PF8100EAES?
The MC33PF8100EAES is specifically configured for the NXP LS1046A processor with DDR4 memory (VDDQ + VTT), as indicated in its OTP programming and datasheet ordering table. It supports the full power tree required for LS1046A's core, I/O, memory, and RTC domains, and is not pre-programmed for i.MX 8 or S32x families unless reconfigured via I²C.
Does MC33PF8100EAES support ASIL B functional safety?
MC33PF8100EAES is qualified to QM (Quality Management) level per ISO 26262 and includes ASIL B-compliant monitoring circuitry (voltage, thermal, watchdog), but lacks the dedicated safety logic (e.g., FSOB assertion states, ABIST-on-demand, secure I²C) found in PF8200 variants. It meets ASIL B *monitoring* requirements but not full ASIL B *system-level fault handling* without external supervision.
What package type and thermal characteristics does MC33PF8100EAES use?
MC33PF8100EAES uses the HVQFN56 package (8 mm × 8 mm × 0.85 mm, 0.5 mm pitch, step-cut wettable flanks). Its thermal resistance is RθJA = 27 °C/W on a 4-layer board, enabling reliable operation up to +105 °C ambient with proper PCB copper pour and EPAD grounding - critical for automotive gateway thermal management.
Can MC33PF8100EAES power DDR4 VTT directly?
Yes, MC33PF8100EAES supports VTT termination mode on SW6, allowing direct regulation of DDR4 VTT (typically 0.6 V) with active sink/source capability. This eliminates the need for external VTT regulators and improves memory bus signal integrity, as confirmed in the functional block diagram and power tree summary.
How is the OTP memory used in MC33PF8100EAES?
The OTP memory in MC33PF8100EAES stores immutable startup configuration - including default output voltages, power-on/off sequencing order, soft-start times, and PGOOD thresholds - enabling fast, repeatable boot without external configuration components. It cannot be rewritten after programming, ensuring consistent behavior across production units.
