Product details
Overview
MC33PT2000AFR2 from NXP Semiconductors is a programmable solenoid controller IC for precision high- and low-side MOSFET gate driving in diesel/gasoline direct injection systems. It integrates seven high-side and eight low-side pre-drivers (two optimized for DC/DC), six current measurement channels, end-of-injection detection, and dual internal regulators (VCCP, VCC2P5). Designed for 12 V automotive and 24 V industrial powertrain applications.
For engineers reviewing the MC33PT2000AFR2 datasheet, MC33PT2000AFR2 pinout, MC33PT2000AFR2 application, or MC33PT2000AFR2 equivalent, key selection criteria include PWM slew rate configurability (four options), VDS monitoring thresholds (eight selectable), integrated diagnostics for HS/LS paths, SPI interface with 16 configurable I/Os, and support for three-bank injector control with full overlap timing.
Technical Context
The MC33PT2000AFR2 implements six concurrent digital microcores across three logic channels-each with dedicated code RAM and data RAM-to execute real-time actuator control with minimal latency. Its architecture supports independent configuration of seven high-side pre-drivers (with integrated charge pumps and bootstrap circuitry) and eight low-side pre-drivers (including LS7/LS8 with higher-frequency capability for DC/DC converter control).
It features dual regulated supplies: VCCP (7.0 V output, fed from battery or external source) powers pre-driver stages up to 72 V, while VCC2P5 (2.5 V internal regulator) supplies the digital core. Battery (VBATT) and boost (VBOOST) voltage monitoring, plus temperature sensing and encrypted microcode, enable ASIL-B–capable functional safety compliance in engine control units.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Battery voltage range | 5.0 V to 72 V - supports both 12 V automotive and 24 V industrial rail inputs without external level shifting. |
| High-side pre-drive count | 7 channels - each with integrated charge pump, bootstrap, and four programmable slew rates for EMI-controlled turn-on/off. |
| Low-side pre-drive count | 8 channels - six for solenoid control, two (LS7/LS8) optimized for >100 kHz DC/DC converter switching. |
| Current measurement channels | 6 independent blocks - four for injector current, two configurable for DC/DC inductor current sensing. |
| VDS monitoring thresholds | 8 selectable levels - enables precise open-load, short-to-battery, and short-to-ground fault detection per channel. |
| Digital interface | SPI with 16 configurable I/Os - allows flexible signal routing for START/FLAG functions and diagnostic feedback without MCU GPIO overhead. |
| Internal clock | 1.0 MHz backup oscillator - ensures deterministic timing during main clock failure or PLL lock loss. |
Pinout & Package
MC33PT2000AFR2 is housed in an 80-pin LQFP package with exposed thermal pad (PGND), optimized for automotive under-hood thermal management and EMC robustness.
| Pin/Terminal | Circuit Role | Design Meaning |

| START1–START7 (Pins 3–9) | Configurable trigger/flag I/Os | Programmable as actuator start triggers or diagnostic flag outputs; support synchronized multi-bank injection timing. |
| FLAG0–FLAG3 (Pins 10–13) | General-purpose I/O / freewheeling control | Can command external freewheeling MOSFET pre-drivers or serve as status indicators for fault conditions. |
Key Features
| Feature | Design Value |
|---|---|

FAQ
What is the operating temperature range for the MC33PT2000AFR2?
The MC33PT2000AFR2 is rated for −40 °C to +125 °C ambient temperature (TA), validated per AEC-Q100 Grade 1 requirements. This range supports placement in engine compartments and transmission control modules where thermal cycling and under-hood heat are critical design constraints. The device's internal temperature sensor and thermal shutdown circuitry ensure safe operation across this full range without external derating.
Does the MC33PT2000AFR2 support DC/DC converter functionality?
Yes, the MC33PT2000AFR2 supports integrated DC/DC converter control using its two dedicated low-side pre-drivers (LS7 and LS8). These channels operate at higher frequencies and support three control modes-manual, hysteretic, and resonant-to minimize power loss in on-board 5 V or 2.5 V supply generation. Current sensing for the DC/DC stage is handled by VSENSEP5/VSENSEN5 and VSENSEP6/VSENSEN6 inputs.
How many current measurement channels does the MC33PT2000AFR2 provide?
The MC33PT2000AFR2 provides six independent current measurement channels. Four are dedicated to solenoid/valve current sensing (VSENSEP1/VSENSEN1 through VSENSEP4/VSENSEN4), while the remaining two (VSENSEP5/VSENSEN5 and VSENSEP6/VSENSEN6) are configurable for DC/DC converter inductor current monitoring. Each channel delivers calibrated analog output via OA_1–OA_3 multiplexed paths.
What safety and diagnostic features are built into the MC33PT2000AFR2?
The MC33PT2000AFR2 includes VDS and VSRC monitoring on all high- and low-side channels with eight programmable thresholds, VBATT and VBOOST voltage supervision, internal temperature sensing, and BIST (MBIST/LBIST) for memory and logic self-test. Its DRVEN pin provides hardware-level fail-safe shutdown, and encrypted microcode prevents unauthorized firmware access-supporting ASIL-B development workflows per ISO 26262.
Is the MC33PT2000AFR2 pin-compatible with other PT2000 variants?
Yes, the MC33PT2000AFR2 is pin-compatible with all members of the PT2000 family sharing the 80-pin LQFP package, including MC33PT2000AER2 and MC33PT2000AFK2 (though the latter uses QFN). Electrical characteristics, register map, and functional behavior are identical across these variants-only differences lie in encryption provisioning and package type.
