NXP Semiconductors MCZ33887EK

Overview

MCZ33887EK from NXP Semiconductors is a monolithic 5.0 A automotive-grade H-bridge power IC with integrated load current feedback (1/375 ratio), active current limiting (5.2–7.8 A), and fault reporting (undervoltage, overtemperature, short-circuit). It operates from 5.0 V to 28 V supply, supports PWM up to 10 kHz, and delivers low R_DS(on) of 120 mΩ typical at 25 °C - used for closed-loop DC motor control in electronic throttle and EGR actuators.

For engineers reviewing the MCZ33887EK datasheet, MCZ33887EK pinout, MCZ33887EK application, or MCZ33887EK equivalent, this page provides verified technical context, HSOP54 package mapping, real-world motor control use cases, and two validated alternative parts with documented functional and application differences.

Technical Context

The MCZ33887EK implements dual half-bridge totem-pole outputs controlled by independent TTL/CMOS-compatible IN1/IN2 inputs and complementary disable inputs D1 (active-high) and D2 (active-low), enabling precise bidirectional motor drive and freewheeling modes. Its internal charge pump sustains gate drive across the full 5.0–28 V operating range.

Current sensing is achieved via a proportional constant-current FB output (1/375 × I_OUT), referenced to AGND and compatible with microcontroller ADCs. Fault detection includes open-drain FS output with undervoltage lockout (V₊ threshold: 4.4–4.75 V), thermal shutdown (175–225 °C), and short-circuit detection on both high-side (11 A) and low-side (8.0 A) MOSFETs.

Key Specifications

Pinout & Package

MCZ33887EK is housed in an HSOP54 package (SOT1747-3): plastic heatsink small outline, 54 terminals, 0.65 mm pitch, 17.9 mm × 7.5 mm × 2.45 mm body, with exposed thermal pad requiring low-impedance DC coupling to AGND and PGND.

FAQ

What is the maximum continuous current rating of the MCZ33887EK?

The MCZ33887EK is rated for 5.0 A continuous DC load current, provided the junction temperature remains ≤ 150 °C. This rating assumes proper PCB thermal design with the exposed thermal pad soldered to AGND/PGND planes. Peak current limiting activates between 5.2 A and 7.8 A to protect against transient overloads.

How does the current feedback (FB) pin function on the MCZ33887EK?

The FB pin on the MCZ33887EK delivers 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). This signal is directly compatible with standard microcontroller ADC inputs, enabling real-time current monitoring for closed-loop torque control or open-load detection without external sensing components.

Does the MCZ33887EK support PWM control, and what is its maximum frequency?

Yes, the MCZ33887EK supports external PWM control of its H-bridge outputs up to 10 kHz. This allows fine-grained speed and torque regulation in motor applications. The device's internal switching characteristics - including 2.0–8.0 µs rise/fall times and ≤18 µs ON/OFF delays - ensure clean waveform fidelity at this frequency without excessive shoot-through or EMI concerns.

What fault conditions does the MCZ33887EK monitor and report?

The MCZ33887EK monitors and reports three primary fault conditions via its open-drain FS pin: undervoltage (V₊ < 4.4 V), overtemperature (junction > 175 °C), and short-circuit (high-side > 11 A or low-side > 8.0 A). All faults force the H-bridge outputs into a latched 3-state condition until cleared by cycling EN or resetting D1/D2.

Is the MCZ33887EK pin-compatible with other members of the MC33887 family?

No, the MCZ33887EK is not pin-compatible with MC33887APVW (HSOP20) or MC33887PFK (HQFN36). It uses the HSOP54 package (SOT1747-3) with 54 terminals, distinct pin count, layout, and thermal pad configuration. Migration requires full PCB redesign - though functional behavior and register-level operation remain consistent across the family.
