Overview
The MAX14870ETC+T is a high-efficiency, compact full-bridge DC motor driver manufactured by Analog Devices Inc./Maxim Integrated. Designed for driving brushed DC motors and relays within a supply voltage range of 4.5V to 36V, it integrates dual half-bridge drivers with control and power stages in a Bi-CMOS process. The device features a 12-TDFN (3x3) package, supports PWM interfaces, and operates across a junction temperature range of -40°C to +150°C.
Feature Summary
- Integrates dual half-bridge drivers with control and power stages for efficient motor management
- Supports wide input voltage ranges from 4.5V to 36V for flexible power supply options
- Includes comprehensive protection mechanisms such as short-circuit, thermal shutdown, and undervoltage lockout
Applications
- Brushed DC motor control in embedded systems
- Relay driving applications requiring compact form factors
- General-purpose motion control circuits
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required tape-and-reel packaging configuration. Ensure compliance with RoHS directives and check for any regional distribution restrictions prior to finalizing procurement orders.
Selection Notes
Select this component for designs requiring integrated power stage solutions without external charge pumps. It is suitable for space-constrained PCB layouts due to its small TDFN footprint. Consider the operating temperature range and current capabilities when designing thermal management strategies for continuous operation.
Part Context
This part belongs to the MAX14870 family of motor drivers, which are optimized for low-power, high-efficiency applications. The series is designed to simplify system design by reducing the number of external components needed for motor control and protection functions.
Replacement Considerations
Consult official documentation for verified substitute part numbers. Cross-reference pinouts and electrical specifications carefully before implementing any alternative components.
