Product details
Overview
MC33HB2001EK from NXP Semiconductors is a SMARTMOS monolithic H-bridge power IC for brushed DC motor control, featuring SPI programmability, 10 A peak output current, 3.0 A continuous average load current, and AEC-Q100 Grade 1 qualification for automotive use in throttle and EGR actuators.
For engineers reviewing the MC33HB2001EK datasheet, MC33HB2001EK pinout, MC33HB2001EK application, or MC33HB2001EK equivalent, this page delivers verified thermal resistance (RΘJCBOTTOM = 0.66 °C/W), 32-pin SOICW exposed-pad package details, real-time current mirror feedback (<5.0 % error), and ISO 26262-compliant diagnostic reporting via SPI.
Technical Context
The MC33HB2001EK implements dual N-channel MOSFET half-bridges with configurable slew rates (0.25–16 V/μs) and four programmable current limits (5.4/7.0/8.8/10.7 A), enabling EMI optimization and thermal management in harsh automotive environments. Its integrated charge pump supports full enhancement of high-side switches across 5.0–28 V VPWR.
SPI-controlled diagnostics include per-output short-to-ground/VPWR detection, open-load sensing, overtemperature warning/shutdown, and VPWR/charge-pump voltage monitoring. The device operates in Sleep, Standby, Normal, and Fault modes, with FS_B providing active-low fault signaling and ENBL/DIS enabling hierarchical power-state control.
Key Specifications

| Operating Supply Range | 5.0–28 V VPWR, covering 12 V automotive battery systems including cold-crank (5 V) and load-dump (40 V transient) |
Pinout & Package
MC33HB2001EK uses a 32-pin SOICW package with thermally enhanced exposed pad (EP), optimized for high-current motor drive applications requiring low RΘJA (23.9 °C/W on 4-layer board) and mechanical compatibility with legacy SOIC footprints.
| Pin/Terminal | Circuit Role | Design Meaning |

FAQ
What is the maximum continuous current rating for the MC33HB2001EK?
The MC33HB2001EK has a nominal continuous average load current rating of 3.0 A at junction temperature ≤150 °C. This value assumes proper PCB thermal design-including connection of the exposed pad (EP) to a low-impedance ground plane-and operation within the 5.0–28 V VPWR range. Peak current capability reaches 16 A for transients under 5 ms.
Does the MC33HB2001EK require an external charge pump capacitor?
Yes, the MC33HB2001EK requires an external 100 nF capacitor connected between the CCP pin and VPWR. This reservoir capacitor is essential for internal charge pump operation, which biases the high-side N-MOSFET gates. Without it, the device cannot fully enhance the high-side switches, resulting in improper H-bridge functionality and potential failure to drive loads.
How does the current mirror output (CFB) on the MC33HB2001EK work?
The CFB pin on the MC33HB2001EK provides a ground-referenced analog current proportional to the high-side output current at a scaling factor of 0.25 %. It delivers less than 5.0 % error across a 2.0–10 A load range. An external resistor (RCFB) converts this current to voltage; for example, 1 kΩ yields 2.5 mV/A. The signal remains stable in noisy environments due to built-in filtering.
Can the MC33HB2001EK operate without SPI communication?
Yes, the MC33HB2001EK can operate without SPI: default settings apply-2.0 V/μs slew rate and 7.0 A current limit threshold. Parallel inputs (IN1/IN2/ENBL/DIS) remain fully functional for basic H-bridge control. However, advanced diagnostics, programmable limits, and fault register access require SPI initialization and polling.
What thermal resistance values define the MC33HB2001EK's cooling performance?
The MC33HB2001EK specifies RΘJCBOTTOM = 0.66 °C/W (junction-to-case bottom), RΘJB = 7.1 °C/W (junction-to-board), and RΘJA = 23.9 °C/W (junction-to-ambient on 4-layer board). These values confirm its suitability for high-power automotive motor drives when mounted with low-thermal-resistance soldering to a thermally robust PCB layout.
