NXP Semiconductors MC33PT2001HAE

Overview

MC33PT2001HAE 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, supporting up to 80 V boost voltage, 100 kHz PWM frequency, and ISO 26262-compliant development for engine injector control in gasoline and diesel direct injection systems.

For engineers reviewing the MC33PT2001HAE datasheet, MC33PT2001HAE pinout, MC33PT2001HAE application, or MC33PT2001HAE equivalent, key selection considerations include its 80 V VBOOST capability (distinguishing it from 72 V variants), absence of integrated end-of-injection detection, HLQFP64 thermal-enhanced package, and SPI-controlled programmable microcore architecture enabling real-time current waveform shaping without MCU intervention.

Technical Context

The MC33PT2001HAE implements a dual-logic-channel architecture with four dedicated 6 MHz digital microcores-two per channel-each with independent code RAM (1024 × 16-bit) and data RAM (64 × 16-bit), enabling concurrent control of two solenoid banks. Its gate drive subsystem includes five high-side predrivers with integrated charge pumps and bootstrap circuitry, plus six low-side predrivers (including G_LS7 dedicated to DC/DC converter control).

Diagnostics are executed autonomously by microcores and include programmable open-load, overvoltage, undervoltage, overcurrent, and overtemperature detection. The device uses a 16-bit SPI interface (up to 10 MHz) with IRQB interrupt output and three flag pins, while safety-critical operation is reinforced by an independent DRVEN pin and embedded encryption for microcode protection.

Key Specifications

Pinout & Package

MC33PT2001HAE is housed in an HLQFP64 (SOT1510-1) thermally enhanced low-profile quad flat package: 10 mm × 10 mm × 1.4 mm body with 0.5 mm pitch and 4.9 mm × 4.9 mm exposed power pad (ePAD) for improved thermal dissipation in under-hood environments.

FAQ

What distinguishes MC33PT2001HAE from other variants in the PT2001 family?

The MC33PT2001HAE is uniquely defined by its 80 V maximum boost voltage capability and absence of integrated end-of-injection (EOI) detection. Unlike MC33PT2001HMAE (which includes both 80 V VBOOST and EOI) or MC33PT2001MAE (72 V VBOOST with EOI), the MC33PT2001HAE targets applications where high-voltage drive is essential but EOI feedback is managed externally or omitted-reducing cost and complexity without sacrificing gate drive performance or safety features.

Does MC33PT2001HAE support ISO 26262 functional safety requirements?

Yes, MC33PT2001HAE was developed in compliance with ISO 26262 up to ASIL-B, with documented safety mechanisms including lockstep microcore monitoring, memory BIST, CRC-protected SPI communication, and independent DRVEN safety inhibit. Full safety documentation-including FMEDA, safety manual, and HW/SW safety analysis-is available from NXP for MC33PT2001HAE to support ASIL-B system integration in automotive powertrain designs.

How many solenoids can MC33PT2001HAE control simultaneously?

The MC33PT2001HAE supports control of up to six solenoids via START1–START6 trigger inputs, with five high-side and six low-side predrivers enabling flexible configurations-including dual-bank operation (e.g., 3+3 or 2+4). Each solenoid is driven by a dedicated high-side predriver and associated low-side switch, with current sensing on up to four channels for closed-loop monitoring and diagnostics.

What package type and thermal characteristics does MC33PT2001HAE use?

MC33PT2001HAE is packaged in HLQFP64 (SOT1510-1): a 10 mm × 10 mm × 1.4 mm thermally enhanced low-profile quad flat package with 0.5 mm pitch and a 4.9 mm × 4.9 mm exposed power pad (ePAD). This construction delivers a junction-to-board thermal resistance (RθJB) of 12.5 °C/W and junction-to-case (RθJC) of 3.2 °C/W, enabling reliable operation at 125 °C ambient in under-hood automotive environments.

Can MC33PT2001HAE operate with both 12 V and 24 V battery systems?

Yes, MC33PT2001HAE supports both 12 V automotive and 24 V commercial vehicle systems. Its VCC5 input accepts 5.0 V ±10 %, VCCIO is configurable for 3.3 V or 5.0 V I/O, and digital IOs tolerate up to 36 V-allowing direct interface to battery-sensed signals. For 24 V systems, an external 7.0 V supply must be provided to VCCP to power the high-side predriver charge pumps, as specified in the datasheet.
