Product details
Overview
MC33PT2001AE from NXP Semiconductors is a programmable solenoid controller IC for automotive powertrain applications, integrating five high-side and six low-side predrivers for logic-level N-channel MOSFETs, 16-bit SPI interface up to 10 MHz, and ISO 26262-compliant development. It supports 72 V max VBOOST, 36 V-tolerant digital I/Os, and operates in gasoline/diesel direct injection systems.
For engineers reviewing the MC33PT2001AE datasheet, MC33PT2001AE pinout, MC33PT2001AE application, or MC33PT2001AE equivalent, key selection considerations include its dual-bank solenoid control architecture, programmable slew rates (12.5–300 V/μs), integrated diagnostics (openload, overcurrent, overtemperature), and HLQFP64 thermal-enhanced package with ePAD grounding.
Technical Context
The MC33PT2001AE implements four concurrent digital microcores-two per logic channel-each with dedicated 1024×16-bit code RAM and 64×16-bit data RAM, enabling real-time current waveform generation without MCU intervention. Its crossbar switch allows flexible routing of analog sensing, SPI, and flag signals across internal resources.
It integrates a 7.0 V linear regulator (VCCP) for gate drive supplies, a 1.5 V regulator (VCC1P5) derived from VCC5, and supports external 3.3 V or 5.0 V I/O supply (VCCIO). The device uses independent DRVEN for functional safety and provides three analog current-sense channels plus optional fourth channel for DC/DC converter monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBOOST Max | 72 V - Enables high-side operation in 24 V truck/industrial systems with margin for transients. |
| PWM Frequency | 100 kHz - Supports fast solenoid current regulation for precise fuel injection timing. |
| Slew Rates | 12.5 V/μs to 300 V/μs - Programmable gate drive edge control to balance EMI and switching loss. |
| SPI Interface | 16-bit slave, ≤10 MHz - High-speed configuration and status reporting with IRQB interrupt signaling. |
| Digital I/O Tolerance | 36 V - Allows direct connection to battery-supplied control lines without level-shifting. |
| Diagnostic Coverage | Openload, undervoltage, overvoltage, overcurrent, overtemperature - On-chip fault detection reduces external monitoring circuitry. |
| Package | HLQFP64 (SOT1510-1), 10 mm × 10 mm × 1.4 mm - Thermally enhanced quad flat package with 4.9 mm × 4.9 mm exposed pad for power dissipation. |
Pinout & Package
MC33PT2001AE is housed in an HLQFP64 (SOT1510-1) thermally enhanced low-profile quad flat package with 0.5 mm pitch and exposed power ground pad (ePAD).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DRVEN | Safety enable input | Independent hardware inhibition signal; deactivates all predrivers when pulled low - critical for ASIL-D system fail-safe behavior. |
| G_HS1–G_HS5 | High-side gate outputs | Five open-drain outputs driving N-channel high-side MOSFET gates; each with integrated bootstrap charge pump and configurable slew rate. |
| G_LS1–G_LS6 | Low-side gate outputs | Six open-drain outputs for N-channel low-side MOSFETs; G_LS7 is dedicated to DC/DC converter control. |

| START1–START6 | Actuator trigger inputs | GPIO-controlled initiation signals for up to six solenoids; also serve as bidirectional flag bus lines for inter-device coordination. |
| IRQB | Interrupt output | Active-low open-drain interrupt indicating diagnostic events, SPI completion, or microcore state changes. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable microcore architecture | Four 6 MHz digital microcores (two per logic channel) execute custom current-shape firmware - offloads waveform generation from host MCU and enables runtime reconfiguration. |
| Integrated end-of-injection (EOI) | On-die EOI detection for each high-side source and low-side drain - eliminates need for external comparators or ADC sampling in GDI/DDI systems. |
| Automatic freewheeling control | Hardware-managed body-diode conduction path between high-side and low-side drivers - reduces energy loss during current decay phase without software overhead. |
| Embedded encryption | AES-based microcode protection with checksum validation - prevents unauthorized firmware extraction or corruption in production ECUs. |
| Two-bank operation mode | Configurable grouping of predrivers into Bank 1 (HS1–HS3 + LS1–LS3) and Bank 2 (HS4–HS5 + LS4–LS6) - supports independent timing and diagnostics per bank in multi-cylinder engines. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar solenoid control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33PT2001HAE | Higher VBOOST rating (80 V vs. 72 V); identical pinout, firmware, and feature set. | Required for 24 V systems with higher transient voltage margins (e.g., heavy-duty truck cold-crank). | Select MC33PT2001HAE if system-level VBOOST transients exceed 72 V; otherwise MC33PT2001AE is cost-optimized. |
| MC33PT2001MAE | Includes integrated end-of-injection (EOI) measurement function; same VBOOST limit (72 V) and package. | Necessary where closed-loop EOI detection is mandated for emission certification (e.g., Tier 4 Final, China VI). | Choose MC33PT2001MAE when EOI feedback is required; MC33PT2001AE omits this block to reduce die size and cost. |
Compared with MC33PT2001HAE and MC33PT2001MAE, the MC33PT2001AE offers the lowest BOM cost for 12 V/24 V powertrain applications where 72 V VBOOST headroom and absence of on-die EOI detection are acceptable design constraints.

FAQ
What is the maximum VBOOST voltage supported by the MC33PT2001AE?
The MC33PT2001AE supports a maximum VBOOST voltage of 72 V. This rating is specified in the ordering information table and confirmed in Section 5 of the short data sheet. It enables reliable high-side predriver operation in 24 V industrial and commercial vehicle systems while maintaining margin against battery transients. The MC33PT2001AE does not support the 80 V VBOOST capability found in the MC33PT2001HAE variant.
Does the MC33PT2001AE include integrated end-of-injection (EOI) detection?
No, the MC33PT2001AE does not include integrated end-of-injection detection. Per Table 1 in the ordering information, the MC33PT2001AE is explicitly described as "without end of injection detection." That function is only present in the MC33PT2001MAE and MC33PT2001HMAE variants. The MC33PT2001AE retains all other core features including programmable microcores, diagnostics, and predriver architecture.
What package type is used for the MC33PT2001AE?
The MC33PT2001AE 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, 1.4 mm height, and a 4.9 mm × 4.9 mm exposed power ground pad (ePAD). This package is documented in Section 10 and Figure 8 of the short data sheet and is shared across all MC33PT2001 variants.
How many high-side and low-side predrivers does the MC33PT2001AE integrate?
The MC33PT2001AE integrates five high-side predrivers (G_HS1–G_HS5) and six low-side predrivers (G_LS1–G_LS6), with G_LS7 reserved for DC/DC converter control. This configuration is confirmed in Sections 1 (General description), 7.1 (Pinning), and 8.2 (Features) of the short data sheet. All predrivers support four programmable slew rates and are managed by four concurrent microcores.
Is the MC33PT2001AE compliant with automotive reliability standards?
Yes, the MC33PT2001AE is qualified per AEC-Q100 Grade 0 (−40 °C to +150 °C junction temperature) and developed in accordance with ISO 26262 for ASIL-B/C automotive safety applications. These qualifications are stated in Sections 2 (Features and benefits) and 12.4 (Suitability for use in automotive applications) of the short data sheet. The device includes safety mechanisms such as independent DRVEN, memory BIST, and diagnostic coverage for critical faults.
