Product details
Overview
MC33HB2000AESR2 from NXP Semiconductors is a SMARTMOS monolithic H-bridge power IC for brushed DC and servo motor control, featuring SPI programmability, 10 A peak output current, 3.0 A nominal continuous current, <5.0 % current-sense error via CFB pin, and AEC-Q100 Grade 1 qualification for automotive throttle and EGR actuator applications.
For engineers reviewing the MC33HB2000AESR2 datasheet, MC33HB2000AESR2 pinout, MC33HB2000AESR2 application, or MC33HB2000AESR2 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), and HVQFN-28 exposed-pad thermal performance (RΘJC(BOTTOM) = 0.39 °C/W).
Technical Context
The MC33HB2000AESR2 implements a full H-bridge topology using four internal N-channel MOSFETs with RDS(on) ≤ 235 mΩ at TJ = 150 °C, enabling bidirectional PWM-controlled motor drive. Its SPI interface supports daisy-chaining and real-time register access for fault status, current limit, and slew rate configuration.
It integrates analog current mirroring (CFB pin outputs 0.25 % of high-side load current), charge pump biasing (CCP pin requires 100 nF to VPWR), and dual protection logic: hardware-level ENBL/DIS controls (Sleep/Standby modes) plus SPI-managed diagnostics including VPWR overvoltage/undervoltage, thermal warning, and open-load detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Output Current | 16 A transient (<5 ms), enabling robust surge handling in automotive start-stop cycles |
| Nominal Continuous Current | 3.0 A average, defining sustained thermal design envelope under natural convection on 4-layer PCB |

| Current Sense Accuracy | <5.0 % error across 2.0–10.0 A load range, enabling precise closed-loop torque control via CFB pin |
| Slew Rate Options | Eight SPI-selectable values from 0.25 V/μs to >16 V/μs, balancing EMI suppression vs. switching loss optimization |
| Thermal Resistance | RΘJC(BOTTOM) = 0.39 °C/W, allowing direct heatsinking through exposed pad to PCB ground plane |
| Diagnostic Coverage | SPI-reportable faults: short-to-ground/VPWR per output, open load, overtemperature, VPWR OV/UV, charge pump UV |
Pinout & Package
MC33HB2000AESR2 uses a 28-pin HVQFN package with 5 mm × 5 mm body and thermally enhanced exposed pad (EP). Pin layout follows Figure 5 in Rev. 8 datasheet; all AGND, DGND, PGND, and EP pins must be low-impedance connected on PCB.

| ENBL | Enable input | Logic HIGH activates full functionality; LOW forces Sleep mode with <50 μA VPWR supply current |
| DIS | Disable input | Logic HIGH places outputs in high-impedance Standby mode while retaining SPI and diagnostic operation |
| CFB | Analog current feedback | Ground-referenced output delivering 0.25 % of high-side load current; enables real-time current monitoring with external RCFB |
| CS_B / SCLK / MOSI / MISO | SPI interface | 16-bit slave interface (daisy-chainable); supports fault register readback, current limit/slew rate writes, and diagnostic clearing |
| FS_B | Fault status flag | Open-drain active-LOW output signaling latched fault conditions per mask register settings |
| VPWR | Main power supply | Must connect all four VPWR pins directly to low-impedance power plane; supports 5–28 V operation and 40 V transients |

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 |
|---|---|---|---|
| MC33883GEKR2 | Single-channel 5 A peak H-bridge; no SPI interface; fixed 2.5 V/μs slew rate; lacks CFB analog feedback | Targeted at cost-sensitive non-safety-critical actuators; no diagnostic reporting capability | Select when SPI configurability, current feedback, and ASIL-B compliance are not required |
| DRV8876NPRGTR | 2.8 A continuous, 7.5 A peak; integrated current sense amplifier (not mirror); no charge pump; 3.3 V logic only | Designed for consumer/industrial DC motors; lacks AEC-Q100 qualification and automotive transient protection | Select for non-automotive applications requiring lower current and simplified layout without CCP capacitor |
Compared with MC33HB2000AESR2, MC33883GEKR2 sacrifices diagnostics and programmability for lower BOM cost, while DRV8876NPRGTR trades automotive robustness and analog feedback for compact size and integrated sensing-neither matches the MC33HB2000AESR2's combination of 10 A peak drive, SPI configurability, and ASIL-B-ready diagnostics.

FAQ
What is the maximum continuous current rating for the MC33HB2000AESR2?
The MC33HB2000AESR2 has a nominal continuous average load current rating of 3.0 A under specified thermal conditions (e.g., four-layer PCB with natural convection). Its peak current capability is 16 A for transients under 5 ms, enabling robust handling of motor inrush and stall conditions without thermal shutdown.
Does the MC33HB2000AESR2 require an external charge pump capacitor?
Yes, the MC33HB2000AESR2 requires an external 100 nF capacitor connected between the CCP pin and VPWR to support internal charge pump operation. Without this capacitor, the device will not function correctly-the charge pump enables full enhancement of the high-side N-channel MOSFETs across the full VPWR range (5–28 V).
How does the CFB pin provide current feedback on the MC33HB2000AESR2?
The CFB pin delivers a ground-referenced analog signal equal to 0.25 % of the high-side output current (e.g., 2.5 mA at 1 A load). With <5.0 % accuracy across 2–10 A, it enables real-time closed-loop torque control. An external resistor (RCFB) converts this current to voltage; unused CFB must be tied to GND via a resistor.
Can the MC33HB2000AESR2 operate without SPI configuration?
Yes, the MC33HB2000AESR2 operates with default settings when SPI is unused: 2.0 V/μs slew rate and 7.0 A current limit threshold. All parallel control inputs (ENBL, DIS, IN1, IN2) remain fully functional, and diagnostics are still reported via FS_B-making it suitable for simpler designs without microcontroller SPI resources.
What thermal performance can be expected from the MC33HB2000AESR2 in HVQFN-28 package?
The MC33HB2000AESR2 in HVQFN-28 achieves RΘJC(BOTTOM) = 0.39 °C/W, enabling efficient heat transfer from die to PCB ground plane via the exposed pad. On a four-layer board, RΘJA is 31.3 °C/W, supporting 3.0 A continuous operation without forced airflow-critical for under-hood automotive environments.
