Product details
Overview
MC33PT2001AER2 from NXP Semiconductors is a programmable SMARTMOS solenoid controller IC for automotive powertrain applications, featuring five high-side and seven low-side predrivers for discrete logic-level MOSFETs, integrated end-of-injection (EOI) detection, 16-bit SPI interface, and ISO 26262-compliant development. It operates in 12 V gasoline direct injection (GDI) and 24 V diesel direct injection (DDI) engine control systems with configurable current profiling via four 6 MHz microcores.
For engineers reviewing the MC33PT2001AER2 datasheet, MC33PT2001AER2 pinout, MC33PT2001AER2 application, or MC33PT2001AER2 equivalent, key selection considerations include its HLQFP64 package, 80 V boost voltage capability (HMAE variant), programmable slew rates (12.5–300 V/μs), dual-bank solenoid control architecture, and embedded diagnostics for openload, overcurrent, overtemperature, and VBOOST/VBATT monitoring.
Technical Context
The MC33PT2001AER2 implements two independent logic channels-each with two dedicated 6 MHz digital microcores, separate code RAM (1024 × 16-bit) and data RAM (64 × 16-bit)-to execute real-time solenoid current shaping without MCU intervention. Its crossbar switch enables concurrent access to analog sensing, SPI, and GPIO resources.
It integrates a 7.0 V linear regulator (VCCP) for gate drive supplies, a 1.5 V regulator (VCC1P5) for digital core, and supports external 3.3 V/5.0 V I/O supply (VCCIO). The device uses individual charge pumps per high-side predriver with 100 % duty cycle capability and includes a dedicated low-side driver (G_LS7) for DC-DC converter control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar solenoid control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PT2000AER2 | No integrated end-of-injection (EOI) detection; lacks VSENSEP4/VSENSEN4 and OA_2; identical pinout and microcore architecture | Suitable for non-EOI applications like transmission solenoids or VVA where precise injection timing is not required | Select MC33PT2000AER2 when EOI functionality is unnecessary and cost reduction is prioritized |
| MC33816AE | 8-channel high-side driver only; no low-side predrivers or microcores; 40 V max VBOOST; SPI-only interface (no STARTx/FLAGx) | Better suited for simpler ON/OFF solenoid control in HVAC or chassis systems-not for closed-loop current shaping | Choose MC33816AE for high-channel-count, low-complexity valve control where programmable current profiling is not needed |
Compared with MC33PT2000AER2 and MC33816AE, the MC33PT2001AER2 uniquely combines programmable microcore-based current shaping, integrated EOI detection, and dual-bank high-/low-side drive-making it the only option among the three capable of full GDI/DDI injector control with diagnostic coverage per solenoid.

FAQ
What is the maximum boost voltage supported by the MC33PT2001AER2?
The MC33PT2001AER2 supports a maximum boost voltage (VBOOST) of 80 V, as confirmed in the ordering information for the HMAE variant. This rating applies to the MC33PT2001HMAE and MC33PT2001HAE versions. The MC33PT2001AER2 suffix indicates tape-and-reel packaging of the HMAE variant, retaining the full 80 V VBOOST specification. Operation above this limit risks permanent damage per absolute maximum ratings.
Does the MC33PT2001AER2 include integrated end-of-injection (EOI) detection?
Yes, the MC33PT2001AER2 includes programmable integrated end-of-injection (EOI) detection, a feature explicitly enabled in the HMAE and MAE variants. The MC33PT2001AER2 corresponds to the HMAE version, which provides EOI measurement for each high-side source and low-side drain without requiring external components. This capability is documented in Section 2 (Features and benefits) and Section 8.2 of the short data sheet.
How many independent current sensing channels does the MC33PT2001AER2 provide?
The MC33PT2001AER2 provides four independent differential current sensing inputs (VSENSEP1/VSENSEN1 through VSENSEP4/VSENSEN4), with OA_1 and OA_2 serving as buffered analog outputs for channels 1 and 2. Channel 4 is optionally configurable for DC-DC converter current monitoring. All four paths are electrically isolated and support simultaneous sampling-critical for multi-injector bank synchronization in GDI and DDI systems.
Is the MC33PT2001AER2 compliant with ISO 26262 functional safety requirements?
Yes, the MC33PT2001AER2 was developed in compliance with ISO 26262, as stated in Section 2 of the short data sheet. It supports ASIL-B decomposition when integrated into a properly architected system. Key enablers include independent DRVEN safety input, redundant diagnostic paths (VBOOST/VBATT monitoring, overtemperature, openload), memory BIST, and encrypted microcode storage-all verified per ISO 26262 Part 6 processes.
What package type and pin count does the MC33PT2001AER2 use?
The MC33PT2001AER2 uses the HLQFP64 (SOT1510-1) package: a 64-terminal, thermally 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 (ePAD). This package is specified in Table 1 (Ordering information) and Figures 8–10 of the short data sheet, and is shared across all MC33PT2001 variants.
