Overview
The MAX22212AUI+ is a dual brushed/single stepper motor driver integrating a high-current 36V, 7.6A MAX H-Bridge. It operates within a supply voltage range of 36V and supports a continuous current of 3.8A per channel. The device functions across an extended temperature range from -40°C to +125°C and is housed in a 28-pin package.
Feature Summary
- Integrates a high-current 36V, 7.6A MAX H-Bridge for robust motor driving capabilities
- Features accurate Current-Drive Regulation (CDR) to limit start-up current and control phase current
- Supports four distinct decay methods including slow, fast, and two mixed decay modes
Applications
- Stepper motor drivers
- Dual brushed DC motor control
- Single stepper motor applications
Procurement Notes
Verify the specific suffix 'AUI+' against the manufacturer's official datasheet to confirm pinout and thermal specifications. Ensure compatibility with the required 36V supply and 3.8A load requirements. Confirm availability through authorized Analog Devices distributors as stock levels fluctuate.
Selection Notes
Select this component when a single IC solution is needed for driving dual brushed or single stepper motors requiring up to 36V and 3.8A. The integrated CDR and multiple decay modes simplify design compared to discrete solutions. Verify that the operating temperature range meets the environmental constraints of the target application.
Part Context
This part belongs to the MAX22212 series of motor drivers from Analog Devices/Maxim Integrated. These devices are designed to provide integrated power stages for motion control applications, reducing board space and component count by combining gate drivers, protection circuits, and power MOSFETs into a single package.
Replacement Considerations
Consult the official Analog Devices cross-reference guide for verified substitutes. Ensure any replacement maintains the 36V rating, 3.8A current capability, and 28-pin TQFN package form factor.
FAQ
What decay modes does the MAX22212AUI+ support?
The device supports four different decay methods: slow decay, fast decay, and two mixed decay modes.
How does the MAX22212AUI+ manage motor current?
It features accurate Current-Drive Regulation (CDR) to limit the start-up current of brushed-DC motors and control the phase current for stepper motors.
