Overview
The MAX22205AUU+T is a dual H-bridge motor driver from Analog Devices/Maxim Integrated, designed for stepper and brushed DC motors. It operates on a supply voltage range of 4.5V to 65V with an output current capacity of 7.6A. The device integrates control and power stages, supporting Step/Direction and PWM interfaces. It features NMOS technology in a 38-TQFN (5x7mm) package with exposed pad. Operating temperature spans -40°C to +125°C.
Feature Summary
- Integrates dual H-bridge drivers with full control logic for simplified system design
- Supports multiple interface modes including Step/Direction and Pulse/Direction
- Includes built-in protection mechanisms against over-current and thermal events
Applications
- Stepper motor control systems
- Brushed DC motor drives
- Industrial automation equipment
- General purpose motor applications
Procurement Notes
Verify the specific suffix 'AUU+T' against official datasheets to confirm tape-and-reel packaging and RoHS compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure ESD handling protocols are followed during assembly due to the exposed pad thermal design.
Selection Notes
Select this component when a compact solution for driving bipolar stepper or brushed DC motors is required. The integrated nature reduces external component count compared to discrete solutions. Verify that the 65V supply limit and 7.6A current rating align with the target motor specifications and thermal management capabilities of the PCB layout.
Part Context
This part belongs to the MAX22205 family of motor drivers. It shares functional similarities with other Maxim Integrated motor control ICs but is distinct in its dual H-bridge configuration and specific interface options. It serves as a complete motion control solution within a single package.
Replacement Considerations
Check for direct pin-compatible alternatives within the MAX22205 series. Verify electrical parameters such as supply voltage and current ratings before substituting with other dual H-bridge drivers.
