Product details
Overview
MC33PT2001HMAER2 from NXP Semiconductors is a programmable solenoid controller IC for automotive powertrain applications, integrating five high-side and seven low-side predrivers for logic-level N-channel MOSFETs, 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 MC33PT2001HMAER2 datasheet, MC33PT2001HMAER2 pinout, MC33PT2001HMAER2 application, or MC33PT2001HMAER2 equivalent, key selection considerations include its 80 V VBOOST rating, integrated EOI measurement, HLQFP64 thermal-enhanced package, 36 V-tolerant digital I/Os, and support for dual-bank solenoid control in engine management systems.
Technical Context
The MC33PT2001HMAER2 implements two independent logic channels-each with two dedicated 6 MHz microcores, separate code RAM (1024 × 16-bit) and data RAM (64 × 16-bit)-to execute real-time current waveform generation for up to six solenoids. Its architecture supports automatic freewheeling control and configurable slew rates (12.5–300 V/μs) across all predrivers.
Diagnostics are executed per-channel via embedded monitoring of VDS, VSRC, VBOOST, VBAT, and temperature, with programmable thresholds for open-load, overvoltage, undervoltage, overcurrent, and overtemperature faults. The device uses an independent DRVEN pin for functional safety shutdown and delivers 16-bit SPI communication at up to 10 MHz with three interrupt flags and IRQB output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Pinout & Package
MC33PT2001HMAER2 is housed in a thermally enhanced HLQFP64 (SOT1510-1) package: 10 mm × 10 mm × 1.4 mm body, 0.5 mm pitch, 4.9 mm × 4.9 mm exposed power pad (ePAD), rated for automotive AEC-Q100 Grade 1 (−40 °C to +125 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DRVEN | Safety enable input | Independent hardware-controlled shutdown path; pulls all predriver outputs low when deasserted. |
| G_HS1–G_HS5 | High-side gate outputs | Drive gates of external N-channel high-side MOSFETs; each with dedicated bootstrap (B_HSx) and source (S_HSx) connections. |
| G_LS1–G_LS6, G_LS7_DC | Low-side gate outputs | G_LS1–G_LS6 drive injector low-side switches; G_LS7_DC controls DC/DC converter low-side MOSFET. |
| VSENSEP1–VSENSEP4 / VSENSEN1–VSENSEN4 | Current sense inputs | Differential analog inputs for four independent current measurement channels; channel 4 configurable for DC/DC converter sensing. |
| START1–START6 | Actuator trigger inputs | GPIO-controlled initiation signals for solenoid firing sequences; also serve as Flag_bus(3–8) in alternate mode. |
| IRQB, FLAG0–FLAG2 | Interrupt & flag outputs | IRQB is active-low interrupt; FLAG0–FLAG2 provide general-purpose status signaling with weak pull-downs. |
| VBOOST, VBATT, VCCP, VCC5, VCCIO | Power supply terminals | VBOOST (up to 80 V) powers high-side predrivers; VBATT supplies drain paths; VCCP (7 V) powers gate drivers; VCC5 (5 V) and VCCIO (3.3/5 V) feed digital/analog domains. |
Key Features
| Feature | Design Value |
|---|---|

| Four 6 MHz microcores | Offloads real-time solenoid current profiling from main MCU, enabling deterministic waveform generation with sub-microsecond latency. |
| Configurable dual-bank operation | Allows independent control of two groups (e.g., 3+3 injectors) with synchronized or staggered firing, optimizing cylinder balancing. |
| Embedded encryption & checksums | Protects microcode against theft and corruption, satisfying secure boot and firmware integrity requirements in ASIL-B/C systems. |
| ISO 26262-compliant development | Supports ASIL-B decomposition in system-level safety architectures, with built-in diagnostics coverage for fault detection and reporting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar solenoid driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PT2000HMAER2 | Lacks integrated end-of-injection (EOI) detection; otherwise identical architecture, pinout, and 80 V VBOOST rating. | Suitable for non-fuel-metering solenoid applications where EOI timing is not required (e.g., transmission shift solenoids). | Select MC33PT2000HMAER2 only if EOI functionality is unnecessary and cost optimization is prioritized. |
| MC33816AE | Single high-side predriver (no low-side outputs); 40 V max VBOOST; no microcores or EOI; SPI-only control. | Targeted at simpler, lower-power solenoid loads (e.g., HVAC actuators) without complex current profiling needs. | Choose MC33816AE for cost-sensitive, single-channel applications lacking dual-bank or EOI requirements. |
Compared with MC33PT2001HMAER2, MC33PT2000HMAER2 removes EOI but retains full programmability and dual-bank capability, while MC33816AE reduces integration to a basic SPI-controlled high-side driver-making both alternatives less suitable for GDI/DDI fuel metering where on-chip EOI and microcore-based waveform control are essential.
