Product details
Overview
MC33HB2001FKR2 from NXP Semiconductors is a SMARTMOS monolithic H-bridge power IC for brushed DC motor control in automotive powertrain systems, featuring SPI-programmable slew rates (0.25–16 V/μs), four selectable current limits (5.4/7.0/8.8/10.7 A), and real-time analog current feedback via CFB pin with <5.0% error. It delivers 10 A peak output, operates from 5.0 V to 28 V, and supports full H-bridge or half-bridge configurations.
For engineers reviewing the MC33HB2001FKR2 datasheet, MC33HB2001FKR2 pinout, MC33HB2001FKR2 application, or MC33HB2001FKR2 equivalent, this page provides verified technical context, validated pin functions, ISO 26262-compliant diagnostic capabilities, thermal resistance data (<1.0 °C/W junction-to-case), and AEC-Q100 Grade 1 qualification details for automotive-grade motor control design.
Technical Context
The MC33HB2001FKR2 integrates dual N-channel MOSFET half-bridges with programmable gate drive slew rates and active current limiting. Its SPI interface enables dynamic configuration of fault thresholds, recirculation modes, and diagnostic reporting-including short-to-ground, short-to-VPWR, open load, overtemperature, and VPWR undervoltage/overvoltage conditions.
It implements a high-side current mirror (CFB) delivering 0.25% of load current with <5.0% accuracy across 2.0–10 A, and uses an internal charge pump (CCP pin) to bias high-side drivers. Thermal protection includes junction temperature warning at 145 °C and shutdown at 150 °C, with junction-to-board thermal resistance of 6.41 °C/W for the PQFN package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | 16 A transient (<5 ms), enabling robust start-up torque for automotive actuators |
| Continuous Average Load Current | 3.0 A nominal, defining steady-state thermal design envelope |
| RDS(on) per MOSFET | Max 125 mΩ at TJ = 150 °C, minimizing conduction loss and heat generation |
| SPI Clock Frequency | 0.5–10 MHz, supporting fast register access and daisy-chained multi-device control |
| Operating Supply Range | 5.0 V to 28 V VPWR, covering cold-crank (5 V) to load-dump (40 V transient) automotive conditions |
| Junction Temperature Range | −40 °C to 150 °C continuous, meeting AEC-Q100 Grade 1 requirements |
| Current Feedback Accuracy | <5.0% error from 2.0 A to 10 A load, enabling precise closed-loop current regulation |
Pinout & Package
MC33HB2001FKR2 uses a 32-pin PQFN package with exposed thermal pad (EP), optimized for low thermal resistance (RΘJC = 0.61 °C/W) and high-power automotive motor drive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1 / OUT2 | H-bridge output terminals | Drive bi-directional brushed DC motors; each connects source of HS and drain of LS MOSFETs |
| IN1 / IN2 | Digital logic inputs | Control direction of current flow; prevent shoot-through by ensuring only one low-side FET is active per half-bridge |
| ENBL | Enable input | Logic HIGH activates full functionality; LOW places outputs in tri-state Sleep mode (IVPWR ≤ 50 μA) |
| DIS | Disable input | Logic HIGH forces outputs to tri-state Standby mode without entering Sleep, preserving SPI communication readiness |
| CFB | Analog current feedback | Delivers 0.25% of high-side load current; used for real-time current monitoring with external RCFB |
| FS_B | Fault status flag | Open-drain active-LOW output signaling faults (e.g., overtemperature, short-circuit) per mask register settings |
| MOSI / MISO / SCLK / CS_B | SPI interface signals | Full-duplex 16-bit slave interface; supports daisy-chaining and fault register readback with rail-to-rail MISO driven by VDDQ |
| VPWR / PGND / AGND / DGND / EP | Power and ground terminals | VPWR pins (12,13,29,30) require low-impedance PCB plane; all GND pins and EP must be connected with minimal impedance for thermal and noise integrity |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar H-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33HB2002FKR2 | Same PQFN-32 package and pinout; adds integrated watchdog timer and enhanced SPI CRC error checking | Required where ASIL-B system-level fault containment requires independent timeout supervision beyond MC33HB2001FKR2's internal diagnostics | Select MC33HB2002FKR2 when watchdog coverage is mandated for ISO 26262 FMEDA analysis |
| DRV8876PWPR | Lower voltage range (4.5–37 V), no SPI interface, fixed 5.5 A current limit, and no current mirror output | Suitable for cost-sensitive non-automotive applications lacking functional safety or diagnostic requirements | Choose DRV8876PWPR only for industrial or consumer designs where AEC-Q100, ISO 26262, and analog current feedback are not required |
Compared with MC33HB2001FKR2, MC33HB2002FKR2 extends safety features with a hardware watchdog, while DRV8876PWPR offers simpler control at the expense of automotive qualification and diagnostic depth-making MC33HB2001FKR2 the optimal balance of configurability, safety, and analog feedback for AEC-Q100-compliant powertrain actuators.

FAQ
What is the maximum transient voltage MC33HB2001FKR2 can withstand on VPWR?
The MC33HB2001FKR2 supports a maximum transient VPWR voltage of 40 V, such as during automotive load-dump events. Exceeding this rating risks avalanche breakdown. External protection-like a Zener clamp or appropriately rated capacitor-is required to ensure safe operation within this limit. This specification is confirmed in Section 7.3.2 and Table 3 of the official NXP datasheet Rev. 10.0.
Does MC33HB2001FKR2 require an external charge pump capacitor?
Yes, MC33HB2001FKR2 requires an external 100 nF capacitor connected between CCP and VPWR pins. The device will not operate correctly without it, as the internal charge pump relies on this reservoir to bias high-side MOSFET gates. This requirement is explicitly stated in Section 7.3.8 and Figure 21 of the NXP datasheet.
Can MC33HB2001FKR2 operate without SPI communication?
Yes, MC33HB2001FKR2 can operate without SPI: it defaults to 2.0 V/μs slew rate and 7.0 A current limit. Parallel control via IN1/IN2, ENBL, and DIS remains fully functional. SPI is optional for advanced configuration-diagnostics, current limit changes, or slew rate adjustment-but not required for basic H-bridge operation.
What is the accuracy and usable range of the CFB current feedback signal in MC33HB2001FKR2?
The CFB pin on MC33HB2001FKR2 provides a current-mirror output equal to 0.25% of the high-side load current, with accuracy better than ±5.0% across a 2.0 A to 10 A load range. This enables reliable analog current sensing without external shunts. The specification is validated in Sections 7.3.7 and 9.2 of the NXP datasheet.
Is MC33HB2001FKR2 pin-compatible with MC33HB2001EK variants?
No, MC33HB2001FKR2 (32-pin PQFN) is not pin-compatible with MC33HB2001EK (32-pin SOICW). Although both share identical pin functions and numbering logic, their physical layouts differ: PQFN has perimeter I/O plus an exposed thermal pad (EP), while SOICW places pins along two sides only. PCB layout and thermal land patterns are not interchangeable.
