概述

Description

MC33926AES is a dual high-current motor-driver IC from NXP (Freescale). It provides two independent H-bridges to drive DC motors from a 5–28 V supply. Each bridge is controlled by logic inputs (IN1/IN2 and IN3/IN4) or PWM for speed and direction, and it includes current-sense outputs for feedback. Protections include undervoltage lockout, overcurrent/short-circuit protection, and overtemperature shutdown, plus deadtime to prevent shoot-through. It’s suited for robotics, hobbyist motor controllers, and small automotive/industrial motors. The AES suffix indicates a specific package/variant; check the datasheet for exact pinout, per-channel current ratings, power dissipation, and thermal data.

Features

Here are the key features of the MC33926AES:
- Dual high-current half-bridge motor driver (two H-bridges) for DC motors.
- Wide operation: 5–28 V nominal motor supply (handles automotive transients).
- Integrated low Rds(on) MOSFETs for high efficiency.
- PWM-compatible inputs to control direction, braking, and speed for each bridge.
- Current monitoring and protection: overcurrent/short-circuit protection with current-limiting; IS pin for motor current feedback.
- Fault protection and diagnostics: UVLO, overtemperature, overcurrent, short-to-GND/short-to-Vcc protections; DIAG/diagnostic output (open-drain) for fault reporting.
- Brake and enable features: dedicated brake function and enable control per bridge.
- Automotive-grade/ AES variant with extended temperature range and robust protection suitable for automotive environments.
- Compact single-package solution reduces BOM and board space.

Package

MC33926AES comes in a 28-pin HTSSOP (Power-SSOP) package with an exposed pad; this is the automotive-grade variant.

Pinout

- Pin count: 28 pins (packages include 28‑pin SOIC/LQFP/DIP).
- Function: Dual high‑current H‑bridge motor driver with current sensing and protection.
- Provides two full bridges (four motor outputs): OUT1/OUT2 (Bridge A) and OUT3/OUT4 (Bridge B).
- Power: VBAT (motor supply) and GND.
- Control: IN1/IN2 for Bridge A, IN3/IN4 for Bridge B (plus enable/drive control as applicable).
- Sensing/limit: IS1/IS2 current-sense outputs with VREF to set current limit.
- Diagnostic: FAULT/DIAG status output.
- Protection: undervoltage, overcurrent, thermal shutdown.

In short: MC33926AES is a 28‑pin dual motor H‑bridge driver with built‑in protection, current sensing, and diagnostic feedback suitable for driving two DC motors from a single device.
