Product details
Overview
MC33HB2000FKR2 from NXP Semiconductors is a SMARTMOS monolithic H-bridge power IC for brushed DC and servo motor control, featuring SPI programmability, 10 A peak current capability, 3.0 A nominal continuous current, <5.0 % error current mirror feedback, and AEC-Q100 Grade 1 qualification for automotive use in throttle and EGR actuators.
For engineers reviewing the MC33HB2000FKR2 datasheet, MC33HB2000FKR2 pinout, MC33HB2000FKR2 application, or MC33HB2000FKR2 equivalent, key selection criteria include SPI-configurable slew rates (0.25–16 V/μs), four selectable current limits (5.4/7.0/8.8/10.7 A), integrated diagnostics (open load, short-to-battery/ground, overtemperature), thermal resistance <1.0 °C/W (junction-to-case), and 5.0–28 V VPWR operation with 36 V I/O tolerance.
Technical Context
The MC33HB2000FKR2 implements a full H-bridge using four internal N-channel MOSFETs with RDS(on) ≤ 235 mΩ at TJ = 150 °C, supporting PWM-controlled bidirectional motor drive. Its SPI interface enables real-time configuration of slew rate, current limit, and operating mode (H-bridge/half-bridge), while diagnostic registers report faults including charge pump undervoltage, VPWR over/undervoltage, and temperature warnings.
Thermal management relies on an exposed thermal pad (EP) with junction-to-case (bottom) resistance of 0.61 °C/W and integrated protection logic that disables outputs on overtemperature, short-circuit, or undervoltage events. The CFB pin delivers 0.25 % of high-side current with <5.0 % accuracy across 2–10 A loads, enabling closed-loop current monitoring without external sensing.

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 |
|---|---|---|---|
| MC33HB2001FKR2 | Same PQFN-32 package and pinout; adds enhanced SPI daisy-chain addressing and extended diagnostic register depth | Required where multi-device SPI bus coordination or deeper fault history logging is needed | Select when system-level diagnostics demand extended register space or synchronized multi-H-bridge control |
| DRV3205QPHPRQ1 | 50 V max VPWR, 12 A peak, 4.5 mΩ RDS(on), no integrated current mirror; requires external sense resistor | Better suited for higher-voltage industrial pumps; lacks analog CFB output and ISO 26262 ASIL-B certification | Choose for non-automotive 24–48 V systems prioritizing ultra-low RDS(on) over integrated diagnostics |
Compared with MC33HB2000FKR2, MC33HB2001FKR2 offers expanded SPI capabilities for complex multi-actuator networks, while DRV3205QPHPRQ1 trades automotive safety compliance and analog feedback for higher voltage rating and lower conduction loss-making each suitable for distinct architecture tiers.

FAQ
What is the maximum peak current rating for the MC33HB2000FKR2 and under what conditions is it specified?
The MC33HB2000FKR2 supports a peak output current of 16 A for transients less than 5.0 ms at junction temperature ≤150 °C. This rating enables high-torque motor start-up in automotive actuators such as throttle valves and EGR flaps. The device maintains this capability within its 5.0–28 V VPWR operating range and is validated per AEC-Q100 Grade 1 specifications. Continuous operation remains limited to 3.0 A average current to ensure thermal stability.
How does the CFB pin on the MC33HB2000FKR2 provide current feedback, and what is its accuracy?
The CFB pin on the MC33HB2000FKR2 delivers a ground-referenced analog signal equal to 0.25 % of the high-side output current, implemented via an internal current mirror. It achieves <5.0 % total error across a 2.0 A to 10 A load range, enabling accurate closed-loop current monitoring without external shunts or amplifiers. An external resistor (RCFB) sets the current-to-voltage gain, and filtering capacitance suppresses high-frequency noise-critical for reliable MCU-based torque control in MC33HB2000FKR2 applications.
Does the MC33HB2000FKR2 require an external charge pump capacitor, and what value is recommended?
Yes, the MC33HB2000FKR2 requires an external reservoir capacitor connected between the CCP pin and VPWR to operate the internal charge pump. A typical value is 100 nF, rated for ≥25 V with low ESR. The device will not function correctly without this capacitor, as it supplies gate bias for the high-side N-channel MOSFETs. The capacitor must be placed close to the CCP and VPWR pins with minimal trace inductance to ensure stable operation across temperature and load conditions in MC33HB2000FKR2 designs.
What are the thermal resistance characteristics of the MC33HB2000FKR2 in its PQFN package?
The MC33HB2000FKR2 in its 32-pin PQFN package has a junction-to-case (bottom) thermal resistance of 0.61 °C/W and a junction-to-board resistance of 6.41 °C/W under JEDEC JESD51-8 conditions. Its junction-to-ambient resistance is 21.55 °C/W on a four-layer board, confirming efficient heat dissipation through the exposed thermal pad (EP). These values validate the device's ability to sustain 3.0 A continuous current in automotive under-hood environments up to 125 °C ambient, as certified under AEC-Q100 Grade 1.
Can the MC33HB2000FKR2 operate without SPI communication, and what are the default settings?
Yes, the MC33HB2000FKR2 can operate without SPI: it defaults to a 2.0 V/μs slew rate and a 7.0 A current limit threshold. All diagnostic reporting and advanced configuration remain disabled, but basic H-bridge functionality-including ENBL/DIS control, IN1/IN2 logic-driven direction, and internal protections-is fully active. This fallback mode supports legacy systems or simplified designs where SPI overhead is unnecessary, while retaining AEC-Q100 Grade 1 reliability and automotive-grade robustness in MC33HB2000FKR2 deployments.
