Product details
Overview
MCZ33887EKR2 from NXP Semiconductors is a monolithic 5.0 A H-bridge power IC with integrated load current feedback (1/375 ratio), fault reporting, and active current limiting (5.2–7.8 A). It operates from 5.0 V to 28 V supply, supports PWM up to 10 kHz, and is AEC-Q100 Grade 1 qualified for automotive motor control applications including electronic throttle and EGR actuators.
For engineers reviewing the MCZ33887EKR2 datasheet, MCZ33887EKR2 pinout, MCZ33887EKR2 application, or MCZ33887EKR2 equivalent, this page delivers verified technical context, HSOP20 package mapping, real-world design meaning of RDS(on), current feedback scaling, thermal shutdown behavior, and validated automotive-grade alternatives - all grounded in NXP's Rev. 17 datasheet.
Technical Context
The MCZ33887EKR2 integrates dual high-side/low-side MOSFETs with 120 mΩ typical RDS(on) at 25 °C, internal charge pump for gate drive above V+, and independent IN1/IN2 polarity control with complementary D1 (active-high) and D2 (active-low) disable inputs. Its 3-state outputs support freewheeling, braking, and sleep mode (≤50 µA).
Current sensing is implemented via a proportional constant-current FB output (1/375 × IOUT), referenced to AGND and compatible with microcontroller ADC inputs. Fault detection includes undervoltage lockout (4.15–4.65 V hysteresis), overtemperature latch (175–225 °C), and short-circuit detection on both high-side (11 A) and low-side (8 A) paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 5.0 A - Sustained DC load current with junction temperature ≤150 °C under proper heatsinking |
| RDS(on) (Typical) | 120 mΩ - Total H-bridge conduction loss per path at V+ = 5–28 V and TJ = 25 °C |
| Current Feedback Ratio | 1/375 - FB pin delivers precise ground-referenced current mirror (e.g., 1.33 mA at 500 mA load) |
| Active Current Limit Range | 5.2–7.8 A - Internally regulated constant-OFF-time PWM threshold for low-side MOSFETs |
| Supply Voltage Range | 5.0–28 V - Fully specified operation; limited functionality up to 40 V with degraded charge pump |
| Operating Temperature | −40 °C to +125 °C ambient - Validated for under-hood automotive environments |
| PWM Frequency Support | Up to 10 kHz - Compatible with standard microcontroller PWM peripherals without external filtering |
Pinout & Package
MCZ33887EKR2 is supplied in HSOP20 (SOT397-2) package: plastic heatsink small outline, 20-pin, 1.27 mm pitch, 11 mm × 15.9 mm × 3.2 mm body, with exposed thermal pad requiring low-impedance connection to AGND/PGND.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| EN (20) | Enable input | Logic high enables full operation; logic low enters ultra-low-power sleep mode (≤50 µA) |
| IN1 (3), IN2 (19) | H-bridge polarity control | TTL/CMOS-compatible inputs directly drive OUT1/OUT2 direction (e.g., IN1=H/IN2=L → forward) |
| D1 (18), D2 (13) | Complementary disable | D1 high or D2 low forces both outputs into high-impedance 3-state; no PCB layout conflict between signals |
| FB (8) | Current feedback output | Ground-referenced constant-current source (IFB = IOUT/375); connects directly to MCU ADC without amplification |
| FS (2) | Fault status output | Open-drain active-low flag indicating undervoltage, overtemperature, or short-circuit; requires 5 V pull-up |
| OUT1 (6,7), OUT2 (14,15) | H-bridge power outputs | Paired pins per output reduce trace inductance and improve current sharing; rated for 5 A continuous |
| V+ (4,5,16), PGND (9–12), AGND (1) | Power and ground terminals | Dedicated V+/PGND pins minimize IR drop; AGND isolated for clean analog feedback reference |
| CCP (17) | Charge pump capacitor | Connects external reservoir capacitor (typically 100 nF ceramic) to sustain gate drive above V+ |

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 |
|---|---|---|---|
| MC33883 | Lower 3.5 A continuous rating; no integrated current feedback; uses external sense resistor | Suitable for cost-sensitive non-automotive applications where closed-loop current monitoring is not required | Select MC33883 only if BOM cost reduction outweighs loss of diagnostic capability and AEC-Q100 qualification |
| DRV8876N | 4.5 A rating; integrated current sense amplifier (not proportional current source); different pinout and enable logic | Targeted at industrial BLDC commutation; lacks AEC-Q100 qualification and automotive thermal robustness | Choose DRV8876N for non-automotive designs needing higher integration density but accept revalidation effort for feedback interface |
Compared with MC33883 and DRV8876N, the MCZ33887EKR2 uniquely combines AEC-Q100 Grade 1 qualification, 5.0 A continuous current, and direct 1/375 current feedback - eliminating external components while meeting automotive functional safety and diagnostic coverage requirements.

FAQ
What is the maximum continuous current rating of the MCZ33887EKR2?
The MCZ33887EKR2 is rated for 5.0 A continuous DC load current, provided the junction temperature remains ≤150 °C under defined thermal conditions (e.g., HSOP20 mounted on 4-layer board with RθJA ≈ 21 °C/W). Peak current limiting activates between 5.2 A and 7.8 A to protect against transient overloads. This rating is validated per NXP's Rev. 17 datasheet and applies specifically to the MCZ33887EKR2 in HSOP20 packaging.
How does the current feedback (FB) pin function on the MCZ33887EKR2?
The FB pin on the MCZ33887EKR2 provides a ground-referenced constant-current output equal to 1/375 of the high-side load current (e.g., 1.33 mA at 500 mA load), enabling direct connection to a microcontroller's ADC without signal conditioning. This ratio is factory-trimmed and stable across temperature, supporting closed-loop torque/speed control and open-load detection. The design meaning is elimination of external sense resistors and amplifiers - a key differentiator confirmed in Section 6.2 and Table 7 of the MCZ33887EKR2 datasheet.
Does the MCZ33887EKR2 support PWM control, and what is its maximum frequency?
Yes, the MCZ33887EKR2 supports external PWM control of its H-bridge outputs up to 10 kHz, as specified in Table 8 of the datasheet. This allows standard microcontroller PWM peripherals to drive motor speed without external gate drivers. The 10 kHz limit balances switching losses and electromagnetic compatibility; operation beyond this frequency risks excessive power dissipation and reduced efficiency. The MCZ33887EKR2's tF/tR of 2–8 µs ensures clean edge transitions at this rate.
What fault conditions does the FS pin report on the MCZ33887EKR2?
The FS pin on the MCZ33887EKR2 is an open-drain active-low output that reports three critical fault conditions: undervoltage (V+ < 4.15 V), overtemperature (junction ≥175 °C, latched), and short-circuit (high-side ≥11 A or low-side ≥8 A). It requires a 5.0 V pull-up resistor and asserts low during any fault, forcing outputs to 3-state. This behavior is documented in Tables 2, 9, and Section 14.2.3 of the MCZ33887EKR2 datasheet and enables immediate system-level response without polling.
Is the MCZ33887EKR2 AEC-Q100 qualified, and for which grade?
Yes, the MCZ33887EKR2 is fully AEC-Q100 qualified for Grade 1, covering operation from −40 °C to +125 °C ambient temperature - a requirement for under-hood automotive applications such as electronic throttle control and EGR valves. This qualification is explicitly stated in Section 1 of the datasheet and verified through stress testing including HTOL, TC, and UHAST. The MCZ33887EKR2's thermal shutdown (175–225 °C hysteresis) and UVLO thresholds are designed to meet Grade 1 reliability targets.
