MC33926AES

MC33926AES is an NXP Freescale dual H-bridge motor driver designed for brushed DC motors. It combines two complete high-side/low-side bridges in one 16-pin package (AES). Each bridge is controlled by two logic inputs (per bridge) plus an enable, with PWM used to set speed and direction. It operates from about 5 to 28 V and can deliver several amps per bridge (with proper heatsinking). A SENSE pin provides current regulation, and the device includes protections such as undervoltage, overcurrent/short, and overtemperature, with a FAULT output for status. It also supports different decay/braking behaviors. Applications include robotics, automotive subsystems, and other compact motor-control tasks where an integrated motor driver is preferred over discrete MOSFETs.

MC33926AES features (concise):
- Dual high-current half-bridge motor driver for DC motors; wide supply range 5–28 V
- Independent bridges controlled by IN1/IN2 and IN3/IN4 (PWM-capable) for bidirectional drive
- Current sensing and regulation via IS pin for closed-loop control
- Fault/diagnostic outputs (DIAG/FAULT) for status monitoring
- Protections: UVLO, overcurrent, overtemperature, short-to-GND, short-to-VBAT, reverse battery protection
- Shoot-through prevention and fast switching suitable for PWM applications
- Automotive-grade AES package for robustness in harsh environments (lead-free)
Notes: Designed for ease of integration with TTL/CMOS logic, offering reliable control of two DC motors from a single device with built-in protection and diagnostics.

MC33926AES is a 28-pin device. It is a dual H-bridge motor driver for brushed DC motors, with built‑in protection and current regulation.
Key pin/function groups:
- Power/ground: VBB (battery supply), GND
- Channel control: IN1/IN2 (channel 1), IN3/IN4 (channel 2)
- Current limit and sense: VREF (sets current limit), IS/SENSE (current-sense output)
- Diagnostic/Status: FAULT/DIAG (diagnostic output)
- Other protection features: overcurrent, undervoltage, overtemperature
In short: 28-pin package, two independent motor bridges with per-channel inputs, power/ground, current-limit and sense, and fault/diagnostic outputs. For exact pin names and numbers, consult the MC33926AES datasheet.

MC33926AES is manufactured by NXP Semiconductors, a Dutch multinational semiconductor company that designs and produces integrated circuits for automotive, industrial, and consumer electronics.

MC33926AES is a dual high‑current half‑bridge motor driver with PWM control and protection features. Typical application areas include:
- Automotive and industrial DC motor drives (12–40V systems)
- Robotics and automation (mobile robots, actuators, conveyors, grippers)
- Automotive actuators (fans, pumps, seat/window/mirror actuators)
- Consumer appliances with DC motors
- Hobbyist/educational robotics and prototyping projects
It is used where two DC motors or a two‑coil stepper need independent, protected drive.

The MC33926AES comes in a 16-pin Small Outline Integrated Circuit (SOIC) package.
