Product details
Overview
MC33PT2001MAE from NXP Semiconductors is a programmable solenoid controller IC for automotive powertrain applications, integrating five high-side and seven low-side predrivers, end-of-injection (EOI) detection, 16-bit SPI interface, and ISO 26262-compliant architecture. It operates with 72 V max VBOOST, supports dual-bank solenoid control, and delivers programmable slew rates up to 300 V/μs for precise current shaping in gasoline and diesel direct injection systems.
For engineers reviewing the MC33PT2001MAE datasheet, MC33PT2001MAE pinout, MC33PT2001MAE application, or MC33PT2001MAE equivalent, this device enables runtime-configurable solenoid drive waveforms via four 6 MHz microcores, integrates diagnostics for openload/overcurrent/overtemperature, and provides dedicated DRVEN safety input and IRQB interrupt signaling - critical for engine control unit (ECU) co-design and functional safety validation.
Technical Context
The MC33PT2001MAE implements two independent logic channels, each with two concurrent digital microcores (UC0CH1/UC1CH1 and UC0CH2/UC1CH2), 1024 × 16-bit code RAM with error detection, and 64 × 16-bit data RAM. Each channel manages separate solenoid banks using configurable PWM timing and automatic freewheeling control.
It features integrated 7.0 V (VCCP) and 1.5 V (VCC1P5) linear regulators, 36 V-tolerant digital I/Os, and a 10 MHz 16-bit SPI slave interface with three interrupt flags (FLAG0–FLAG2) and IRQB output. The EOI measurement function is explicitly enabled for MC33PT2001MAE per ordering information.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| START1–START6 | Actuator trigger inputs | GPIO-controlled start signals (PU/PD configurable) that initiate microcore-executed current profiles for individual injectors. |
| IRQB | Interrupt output | Open-drain active-low signal indicating diagnostic events, EOI completion, or SPI command completion. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable microcore architecture | Four 6 MHz digital microcores with dedicated code/data RAM enable runtime waveform reconfiguration without MCU intervention. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar solenoid controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PT2001HMAE | Higher VBOOST rating (80 V vs. 72 V); identical EOI functionality, pinout, and microcore architecture. | Preferred for 24 V truck/bus platforms requiring extended boost headroom during cold-crank transients. | Select MC33PT2001HMAE only if system VBOOST must exceed 72 V; otherwise MC33PT2001MAE offers optimal cost/performance balance. |
| MC33816AE | Single high-side predriver (vs. five), no EOI detection, lower integration (no DC/DC predriver), SPI-only interface (no FLAG/START GPIOs). | Targeted at simpler solenoid loads (e.g., idle air control, purge valves) without closed-loop injection timing needs. | Choose MC33816AE for cost-sensitive non-injector applications where full PT2001 feature set is unnecessary. |
Compared with MC33PT2001HMAE, MC33PT2001MAE trades 8 V VBOOST headroom for optimized thermal performance in 12 V GDI systems; versus MC33816AE, it delivers full multi-injector control with EOI, making it irreplaceable for modern direct injection ECUs.

FAQ
What is the maximum VBOOST voltage supported by the MC33PT2001MAE?
The MC33PT2001MAE supports a maximum VBOOST voltage of 72 V, as specified in the official NXP ordering information table. This rating enables reliable high-side gate drive in 12 V automotive systems with margin for battery transients. Exceeding 72 V risks permanent damage and voids AEC-Q100 qualification compliance. The MC33PT2001HMAE variant supports 80 V for 24 V platform use cases.
Does the MC33PT2001MAE include end-of-injection (EOI) detection functionality?
Yes, the MC33PT2001MAE includes integrated end-of-injection detection, explicitly confirmed in the NXP ordering information: "MC33PT2001MAE - Programmable solenoid controller with measurement function and VBOOST max at 72 V, with end of injection detection." This feature operates without external components and is implemented in analog front-end circuitry tied to VSENSE inputs.
How many high-side and low-side predrivers does the MC33PT2001MAE provide?
The MC33PT2001MAE provides five high-side predrivers (G_HS1–G_HS5) and seven low-side predrivers (G_LS1–G_LS7), with G_LS7 dedicated to DC/DC converter control. This configuration is fixed per the internal block diagram and pin definitions in the NXP short data sheet Rev. 10.1, and supports dual-bank solenoid actuation with flexible current path routing.
Is the MC33PT2001MAE compliant with ISO 26262 functional safety standards?
Yes, the MC33PT2001MAE is developed in compliance with ISO 26262, as stated in Section 2 ("Features and benefits") of the NXP short data sheet. This includes safety-oriented design practices, diagnostic coverage documentation, and support for ASIL-B system integration - verified through NXP's certified development process, not third-party certification of the part itself.
What package type is used for the MC33PT2001MAE?
The MC33PT2001MAE uses the HLQFP64 (SOT1510-1) package: a thermally enhanced low-profile quad flat package with 64 terminals, 0.5 mm pitch, 10 mm × 10 mm body, and a 4.9 mm × 4.9 mm exposed power pad (ePAD). This package is explicitly listed in Table 1 of the NXP short data sheet Rev. 10.1 for all MC33PT2001 variants including MC33PT2001MAE.
