Overview
The MAX22202ATC+ is a 36V brushed DC motor driver with integrated current sense. It features a full bridge with very low impedance FETs, typical RON of 300mΩ (high side + low side) at TA = +25°C. Rated peak current is 3.5A and RMS current is 2A at +25°C. It includes configurable current drive regulation (CDR) to limit stall and inrush currents. The device integrates lossless current sensing (ICS), eliminating the need for external resistors. Protection functions include overcurrent protection (OCP), undervoltage lockout (UVLO), and thermal shutdown (TSD). It operates within an ambient temperature range of -40°C to +125°C.
Feature Summary
- Integrates a 36V full-bridge with very low impedance FETs for high efficiency
- Features configurable current drive regulation to manage stall and inrush conditions
- Includes lossless integrated current sensing without external shunt resistors
- Provides comprehensive protection via overcurrent, undervoltage lockout, and thermal shutdown
Applications
- Brushed DC motor driving
- Latching valve control
- Solenoid actuation
- Single-phase stepper motor driving
Procurement Notes
Verify the specific suffix ATC+ corresponds to the TDFN12 3mm x 3mm package when sourcing. Confirm the manufacturer is Analog Devices or Maxim Integrated. Ensure the component meets RoHS compliance standards as indicated by the plus sign. Cross-reference the ordering number with official distributor catalogs to avoid counterfeit parts. Check for any specific environmental or handling requirements listed in the latest datasheet revision.
Selection Notes
Select this component for space-constrained applications requiring efficient brushed DC motor control. The integrated current sensing simplifies design by removing external sense resistors. Consider the 3.5A peak and 2A RMS ratings against your thermal management capabilities. The small TDFN12 package is suitable for dense PCB layouts. Evaluate the need for current drive regulation if operating near stall conditions.
Part Context
This part belongs to the MAX2220x family of single-channel motor drivers from Analog Devices/Maxim Integrated. It shares architectural similarities with the MAX22201 and MAX22207 but differs in specific pinouts and feature sets like the presence of CDR monitor outputs in other variants. The family targets compact motor control solutions with integrated power stages.
Replacement Considerations
Direct substitutes within the same series include the MAX22201ATC+ and MAX22207ATC+. Verify pin compatibility and feature parity, such as the availability of current drive regulation monitoring. Ensure the replacement maintains the required 36V rating and current capacity.
