Descripción general

Description

MC33888FB is an automotive-grade four-channel switch IC from NXP/Freescale. It lets you drive inductive loads (DC motors, solenoids, relays) directly from a microcontroller by providing four integrated high-side/low-side switches.
Key features:
- Four independently controllable switches
- Protection: overcurrent with current limit, undervoltage lockout, overtemperature, short-to-ground/short-to-VCC
- Diagnostic/status outputs for MCU feedback
- PWM-capable with simple logic-level control
The FB suffix designates a specific package/temperature variant of the device. Typical uses include automotive actuators (power windows, seat/HVAC actuators, door locks) and other high-current loads where external transistors aren’t desired.

Features

MC33888FB features (concise):
- Dual full-bridge motor driver with integrated MOSFETs for DC motors or stepper motors
- Independent control: IN1/IN2 and IN3/IN4 per bridge plus ENABLE; PWM speed control supported
- Logic compatible with 5 V MCU logic
- Built-in protection: undervoltage lockout, overcurrent/short-circuit protection, overtemperature shutdown
- Current limiting and fault protection with diagnostic/FAULT output
- Inductive-load protection and flyback diodes; shoot-through prevention
- Wide supply range suitable for automotive/industrial use; RoHS lead-free package (FB)
- Small 8-pin package options; suitable for compact designs
Applications: automotive/robotics DC motor drive, small stepper motors.

Package

MC33888FB is available in a 28-pin small‑outline package (SO-28), e.g., TSSOP/SOIC variants.

Pinout

- Pin count: 8 pins (8-pin package, e.g., SO-8/DIP-8).
- Function: Dual high-current motor driver (two H-bridge/half-bridge channels) with built-in protection (current limit, fault/diagnostic) for driving DC motors. Inputs control each channel; outputs drive the motor, with Vcc and GND pins provided.

Manufacturer

- Manufacturer: NXP Semiconductors (currently; originally Freescale Semiconductor, Motorola’s chip unit).
- Company type: Dutch multinational semiconductor company that designs and manufactures integrated circuits and embedded processing solutions for automotive, industrial, and consumer electronics.

Application

MC33888FB is a high-speed CAN transceiver. Typical application areas:
- Automotive in-vehicle networks (ECUs, body/chassis electronics, gateways, instrument clusters)
- Industrial CAN networks (CANopen, machine automation, robotics, instrumentation)
- Telematics and fleet-management devices interfacing with CAN buses
- Any system needing robust CAN signaling with fault protection and low-power wake/sleep in automotive/industrial environments
