Product details
Overview
MC33PT2001HMAE from NXP Semiconductors is a programmable solenoid controller IC for automotive powertrain applications, integrating five high-side and seven low-side predrivers, 80 V boost voltage capability, end-of-injection (EOI) detection, and four concurrent 6 MHz microcores. It serves as a SMARTMOS gate driver in gasoline/diesel direct injection systems with SPI control and ISO 26262-compliant development.
For engineers reviewing the MC33PT2001HMAE datasheet, MC33PT2001HMAE pinout, MC33PT2001HMAE application, or MC33PT2001HMAE equivalent, this page delivers verified technical context, HLQFP64 package mapping, real-time current profiling, integrated diagnostics (openload/overcurrent/overtemperature), and validated alternative options for solenoid control system design.
Technical Context
The MC33PT2001HMAE implements two logic channels-each with dual 6 MHz microcores, dedicated code RAM (1024 × 16-bit) and data RAM (64 × 16-bit)-to execute independent solenoid current waveforms without MCU intervention. Its architecture supports banked 2×3 injector control with automatic freewheeling and configurable slew rates (12.5–300 V/μs) per predriver.
It integrates a 7.0 V linear regulator (VCCP) for gate drive supply, 1.5 V regulator (VCC1P5) for digital core, and selectable 3.3/5.0 V I/O supply (VCCIO). Diagnostics include VBOOST/VBAT monitoring, VDS/VSRC fault detection, and embedded encryption for microcode protection-all qualified to AEC-Q100 Grade 0.

Applications
| Gasoline Direct Injection (GDI) | Diesel Direct Injection (DDI) |
|---|---|
Use Scenario: High-pressure fuel injection in turbocharged gasoline engines requiring precise 1–3 ms current pulses with adaptive peak-and-hold profiles. IC Role / Device Role / Timing Role: Solenoid gate driver executing real-time current waveform generation via microcores, with EOI detection confirming needle lift closure.

IC Role / Device Role / Timing Role: Dual-bank predriver managing up to six injectors with independent slew-rate tuning per phase to suppress mechanical noise and rail pressure ripple. Use Value: Achieves <±1% pulse width accuracy at 100 kHz PWM-critical for NOx/soot trade-off optimization in Euro 6+ aftertreatment systems. |
| Variable Valve Actuation (VVA) | Transmission Solenoid Control |
Use Scenario: Electromechanical valve train actuation in 4-valve-per-cylinder engines, requiring rapid (<5 ms) bidirectional current reversal for latching/unlatching. IC Role / Device Role / Timing Role: High-side/low-side predriver pair per valve, coordinated by microcores to generate asymmetric current ramps for controlled magnetic force sequencing. Use Value: Enables camless valve timing with <100 μs current transition control-improving volumetric efficiency across 0–7000 RPM range. | Use Scenario: Pressure modulation in wet-clutch CVT and DCT transmissions using proportional solenoids with 0–2 A continuous current. IC Role / Device Role / Timing Role: Low-noise current regulator with integrated diagnostics detecting coil open/short and thermal derating before clutch slip occurs. Use Value: Reduces transmission shift jerk by maintaining <±0.05 A current stability under 12–24 V battery transients-meeting JASO M347 compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar solenoid driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PT2001HAE | Lacks integrated end-of-injection (EOI) detection circuitry; otherwise identical pinout, 80 V boost, and microcore architecture | Suitable for non-critical injection timing applications where EOI feedback is handled externally or omitted | Select MC33PT2001HAE only if EOI functionality is not required-reduces cost while retaining full predriver capability |
| MC33PT2001MAE | Supports EOI detection but limited to 72 V max boost voltage; same HLQFP64 package and SPI interface | Fits 12 V automotive platforms with lower boost requirements; not suitable for 80 V GDI systems | Choose MC33PT2001MAE for cost-sensitive 12 V applications needing EOI but not 80 V headroom |
Compared with MC33PT2001HAE and MC33PT2001MAE, the MC33PT2001HMAE uniquely combines 80 V boost capability *and* integrated EOI detection-making it the only option for high-pressure GDI systems requiring both extended voltage headroom and closed-loop injection timing verification.

FAQ
What is the maximum boost voltage supported by the MC33PT2001HMAE?
The MC33PT2001HMAE supports a maximum boost voltage of 80 V, as explicitly specified in its ordering information and short data sheet. This rating applies directly to the VBOOST pin (Pin 48) and enables high-side predriver operation in demanding gasoline and diesel direct injection systems. The 80 V capability distinguishes MC33PT2001HMAE from variants like MC33PT2001MAE (72 V) and is validated for continuous operation under AEC-Q100 stress conditions.
Does the MC33PT2001HMAE include end-of-injection (EOI) detection?
Yes, the MC33PT2001HMAE includes integrated end-of-injection detection functionality, confirmed in both the feature list ("Programmable integrated End-of-Injection (EOI) measurement function (MC33PT2001HMAE and MC33PT2001MAE)") and ordering information ("with measurement function and VBOOST max at 80 V, with end of injection detection"). This capability operates per channel without external components and is a key differentiator from MC33PT2001HAE.
How many high-side and low-side predrivers does the MC33PT2001HMAE provide?
The MC33PT2001HMAE provides five high-side predrivers (HS1–HS5) and seven low-side predrivers (LS1–LS7), with LS7 dedicated to DC/DC converter control. This configuration is documented in the General Description ("integrated high-side (x5), and low-side (x7) predrivers") and Pin Definitions table, and is physically mapped to pins G_HS1–G_HS5 and G_LS1–G_LS7 in the HLQFP64 package.
Is the MC33PT2001HMAE compliant with functional safety standards?
Yes, the MC33PT2001HMAE is developed in compliance with ISO 26262, supporting ASIL-B decomposition in automotive powertrain systems. This is stated in the Features section ("ISO 26262 compliant development") and reinforced by AEC-Q100 qualification (Grade 0), integrated diagnostics (openload/overcurrent/overtemperature), and independent DRVEN safety pin-enabling safe torque interruption in engine control units.
What package type is used for the MC33PT2001HMAE?
The MC33PT2001HMAE uses the HLQFP64 package (SOT1510-1): a thermally enhanced low-profile quad flat package with 64 terminals, 0.5 mm pitch, 10 mm × 10 mm body, and 4.9 mm × 4.9 mm exposed power pad. This package is confirmed in Table 1 (Ordering Information) and Figures 8–10 of the short data sheet, and is shared across all MC33PT2001 variants.
