MAX14872ETC+T

Overview

The MAX14872ETC+T is a high-efficiency, compact full-bridge DC motor driver designed for brushed DC motors and relays. It operates on a supply voltage range of 4.5V to 36V and supports peak currents up to 3A. The device utilizes a 12-pin TDFN (3x3mm) package with an exposed pad for thermal management. Key electrical parameters include a typical bridge on-resistance of 280mΩ at 25°C and a standby current of 10µA maximum in shutdown mode. It features integrated fast decay current regulation and independent voltage detection inputs.

Feature Summary

Compact design with no charge pump architecture to minimize external component count
Integrated fault diagnosis output indicating thermal overload or overcurrent conditions
Independent voltage detection input to reduce current sensing errors from parasitic trace resistance

Applications

Brushed DC motor control systems
Relay driving applications
Battery-powered devices requiring low standby power

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and thermal specifications. Confirm RoHS compliance status through manufacturer declarations. Ensure the supplier provides valid traceability for the TDFN-EP package type.

Selection Notes

Select this component when space constraints require a small footprint alongside high current handling capabilities. The absence of a charge pump simplifies PCB layout compared to similar drivers. Consider the thermal performance requirements given the exposed pad design for heat dissipation during high-load operations.

Part Context

This part belongs to the MAX14870/MAX14872 family of efficient, compact full-bridge DC motor drivers. These devices are engineered to provide robust motor control solutions with minimal external circuitry requirements, focusing on efficiency and reliability in industrial and consumer electronics.
