TMC1620-TO

Overview

The TMC1620-TO is a power MOSFET chip designed for high-efficiency motor driver applications. It features an N-channel and P-channel enhancement mode configuration within a single TO-252-4L package measuring 6.5x10mm. The N-channel variant supports a rated voltage of 60V with a typical on-resistance of 36mΩ and a maximum continuous current of 6.6A. The P-channel variant operates at -60V, offering 75mΩ on-resistance and a maximum continuous current of -4.7A. These components are utilized in stepper motor drivers like the TMC262 to provide low conduction losses and rapid switching performance.

Feature Summary

Enhancement mode construction for both N-channel and P-channel configurations
Low on-resistance characteristics to minimize energy loss during operation
Rapid switching capability to support precise motor control algorithms
Integrated thermal management design for effective heat dissipation

Applications

Stepper motor driver circuits requiring efficient power conversion
High-power density power supply systems
Precision positioning platforms demanding smooth motion control
Medical equipment utilizing quiet and accurate motor actuation

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance and halogen-free status prior to integration. Ensure proper handling procedures are followed due to surface mount packaging requirements. Validate datasheet specifications against specific application voltage and current demands before finalizing procurement decisions.

Selection Notes

Select the TMC1620-TO when designing two-phase or three-phase stepper motor drivers requiring integrated power stages. The combined N/P channel architecture simplifies circuit layout compared to discrete solutions. Evaluate thermal performance requirements based on the 36mΩ and 75mΩ resistance values to ensure adequate heat sinking for sustained 6.6A and -4.7A loads respectively.

Part Context

This component serves as the core power element within Maxim Integrated's TMC series of stepper motor drivers. It replaces external discrete MOSFETs in designs such as the TMC262 and TMC389. By integrating these power switches into a compact TO-252-4L package, it reduces overall system volume and complexity while maintaining high energy efficiency and thermal stability in industrial automation environments.
