Design files

Overview

This reference design features the Hall-effect current sensor, TMCS1100, that can measure currents with an absolute error of < 1% (–40 to 125°C) and provide a working isolation voltage of up to 600 V. The low-resistance in-package current sensing element and lack of need for high-side power supply enable a compact and efficient current sensing solution for precise motor torque, speed, or position control. The inverter power stage is comprised of 600-V LMG3411 Gallium Nitride (GaN) power modules enabling further size reduction and efficiency improvement for the next-generation of motor drives.

Features

Accurate current sense (< 1% absolute error) enables precise motor control.
Accuracy stability over a wide temperature range eliminates the need for external offset or drift compensation.
In-package sense element, and a lack of need for high-side power supply enable a small footprint, low-cost current-sense system.
Efficient and compact inverter power stage is based on 600-V LMG3411 GaN power modules with integrated gate under-voltage, device overcurrent, and over-temperature protection.
