Product details
Overview
MC33PT2001HAER2 from NXP Semiconductors is a programmable SMARTMOS solenoid controller IC for automotive powertrain applications, featuring five high-side and seven low-side predrivers for logic-level N-channel MOSFETs, 100 kHz PWM capability, four programmable slew rates (12.5–300 V/μs), and integrated end-of-injection detection. It operates in 12 V gasoline and 24 V diesel/truck systems with VBOOST up to 80 V.
For engineers reviewing the MC33PT2001HAER2 datasheet, MC33PT2001HAER2 pinout, MC33PT2001HAER2 application, or MC33PT2001HAER2 equivalent, this device supports SPI-controlled solenoid current shaping, automatic freewheeling, ISO 26262-compliant diagnostics (openload, overcurrent, overtemperature), and safety-critical engine control functions including GDI, DDI, and variable valve actuation.
Technical Context
The MC33PT2001HAER2 implements two independent logic channels, each with dual 6 MHz programmable microcores (UC0CH1/UC1CH1 and UC0CH2/UC1CH2), dedicated code RAM (1024 × 16-bit) and data RAM (64 × 16-bit), enabling concurrent real-time solenoid current waveform generation without MCU intervention. Its architecture integrates a crossbar switch, signature unit, and memory BIST for secure, deterministic control.
It supports dual-bank operation with configurable STARTx trigger inputs, IRQB interrupt output, and three independent analog current sense channels (VSENSEP1/N1 through VSENSEP3/N3), plus a fourth channel optionally assigned to DC/DC converter monitoring. Diagnostics include VDS/VSRC monitoring, VBOOST and VBAT supervision, and embedded temperature sensing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar solenoid control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PT2001HMAER2 | Includes integrated end-of-injection (EOI) measurement function; same 80 V VBOOST rating. | Required for applications needing closed-loop injection timing verification (e.g., emission-critical GDI). | Select MC33PT2001HMAER2 when EOI detection is mandatory; otherwise MC33PT2001HAER2 reduces firmware complexity. |
| MC33PT2001MAER2 | 72 V VBOOST max; includes EOI function; lacks 80 V boost capability. | Suitable for 12 V gasoline-only platforms where 80 V headroom is unnecessary. | Choose MC33PT2001MAER2 for cost-sensitive 12 V designs requiring EOI but not 80 V operation. |
Compared with MC33PT2001HAER2, MC33PT2001HMAER2 adds EOI functionality without sacrificing VBOOST headroom, while MC33PT2001MAER2 trades 8 V boost margin for EOI at lower voltage-making HAER2 optimal for 24 V diesel systems without EOI dependency.

FAQ
What is the maximum VBOOST voltage supported by the MC33PT2001HAER2?
The MC33PT2001HAER2 supports a maximum VBOOST voltage of 80 V, enabling robust high-side gate drive for 24 V truck and diesel applications. This rating is confirmed in the ordering information table and distinguishes it from the 72 V variants (e.g., MC33PT2001MAER2). The 80 V capability ensures sufficient gate overdrive margin under worst-case transients in heavy-duty powertrain systems.
Does the MC33PT2001HAER2 include integrated end-of-injection (EOI) detection?
No, the MC33PT2001HAER2 does not include integrated end-of-injection detection. Per the ordering information table, only the HMAE and MAE variants feature EOI functionality. The HAER2 variant provides the 80 V VBOOST capability without EOI, making it suitable for applications where timing is managed externally or where EOI is not required for compliance.
How many high-side and low-side predrivers does the MC33PT2001HAER2 integrate?
The MC33PT2001HAER2 integrates five high-side predrivers and seven low-side predrivers. Six of the low-side outputs (G_LS1–G_LS6) drive solenoid actuators, while G_LS7 is dedicated to controlling the external MOSFET in the integrated DC/DC boost converter. All predrivers support four programmable slew rates and operate up to 100 kHz PWM frequency.
Is the MC33PT2001HAER2 qualified for automotive use?
Yes, the MC33PT2001HAER2 is qualified in compliance with AEC-Q100 Grade 0 (−40°C to +150°C ambient), and its development follows ISO 26262 ASIL-B requirements. It is designed specifically for automotive powertrain applications including GDI, DDI, and variable valve actuation, with built-in diagnostics for openload, overcurrent, overtemperature, and supply monitoring.
What package type is used for the MC33PT2001HAER2?
The MC33PT2001HAER2 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 specified in the ordering information table and supports high-power dissipation in engine compartment environments.
