NXP Semiconductors MC33PT2001MAER2

Overview

MC33PT2001MAER2 from NXP Semiconductors is a programmable solenoid controller IC for automotive powertrain applications, specifically supporting gasoline and diesel direct injection systems with end-of-injection (EOI) detection. It integrates five high-side and seven low-side predrivers, four 6 MHz programmable microcores, and supports VBOOST up to 72 V. Its role is to autonomously manage solenoid current waveforms while offloading timing-critical control from the main MCU.

For engineers reviewing the MC33PT2001MAER2 datasheet, MC33PT2001MAER2 pinout, MC33PT2001MAER2 application, or MC33PT2001MAER2 equivalent, this device is selected for high-reliability engine control where precise EOI measurement, ISO 26262-compliant diagnostics, and flexible PWM slew rate configuration (12.5–300 V/μs) are required in 12 V/24 V powertrain systems.

Technical Context

The MC33PT2001MAER2 implements two independent logic channels, each with dual microcores (UC0CH1/UC1CH1 and UC0CH2/UC1CH2), dedicated code RAM (1024 × 16-bit) and data RAM (64 × 16-bit), enabling concurrent real-time solenoid control. Its architecture includes integrated bootstrap circuitry per high-side predriver and a dedicated low-side driver (G_LS7) configurable for DC-DC boost conversion.

Diagnostics are executed in hardware by the microcores: VDS/VSRC monitoring, VBOOST and VBAT supervision, temperature sensing, and open-load/overcurrent/undervoltage/overvoltage detection-all programmable and reported via SPI or FLAGx pins. The device uses a 16-bit SPI interface (up to 10 MHz) with IRQB and three interrupt flags for deterministic fault response.

Key Specifications

Pinout & Package

MC33PT2001MAER2 is housed in an HLQFP64 (SOT1510-1) package: plastic thermal-enhanced low-profile quad flat package, 64 terminals, 0.5 mm pitch, 10 mm × 10 mm × 1.4 mm body, with 4.9 mm × 4.9 mm exposed power pad (ePAD).

Equivalent & Alternatives

The following parts are listed as comparable options for similar solenoid control applications.

Compared with MC33PT2001HMAE, MC33PT2001MAER2 offers identical EOI, diagnostics, and microcore flexibility but with 72 V VBOOST-sufficient for most 12 V/24 V powertrains-while MC33816AE lacks programmability, EOI, and dual-bank capability, making it unsuitable for advanced injection timing.

FAQ

What is the maximum VBOOST rating for MC33PT2001MAER2?

The MC33PT2001MAER2 supports a maximum VBOOST of 72 V, as confirmed in the ordering information table and functional description section of the short data sheet. This rating enables reliable high-side gate driving for solenoids in both 12 V and 24 V automotive powertrain systems while maintaining margin against transients. Exceeding 72 V may compromise device reliability and is outside the specified operating range.

Does MC33PT2001MAER2 include end-of-injection (EOI) detection?

Yes, MC33PT2001MAER2 includes integrated end-of-injection detection, explicitly stated in the part description for "MC33PT2001MAE" (the base variant of MC33PT2001MAER2). This function operates without external components and provides accurate EOI timing per high-side source and low-side drain, essential for closed-loop fuel metering in GDI and DDI systems.

How many high-side and low-side predrivers does MC33PT2001MAER2 integrate?

MC33PT2001MAER2 integrates five high-side predrivers (G_HS1–G_HS5) and seven low-side predrivers (G_LS1–G_LS7), with G_LS7 configurable for DC-DC converter control. This configuration is documented in the general description, pin definitions, and internal block diagram sections of the short data sheet, supporting dual-bank solenoid control with flexible actuator assignment.

Is MC33PT2001MAER2 compliant with ISO 26262?

Yes, MC33PT2001MAER2 is developed in compliance with ISO 26262, as explicitly stated in the Features and Benefits section. This includes full tool qualification, requirements traceability, and fault injection testing-supporting integration into ASIL-B automotive safety-related systems such as engine control units without requiring additional safety mechanisms at the IC level.

What package type is used for MC33PT2001MAER2?

MC33PT2001MAER2 uses the HLQFP64 (SOT1510-1) package: a 64-terminal thermal-enhanced low-profile quad flat package with 0.5 mm pitch, 10 mm × 10 mm body, and 4.9 mm × 4.9 mm exposed power pad. This package is confirmed in the Ordering Information table and Package Outline section of the short data sheet.
