This application note describes the evaluation board of the DMOS fully integrated stepper motor driver L6228Q. The board implements a typical application that can be used as a reference design to drive two-phase bipolar stepper motors with currents up to 1 A DC.

The DRV8662EVM Evaluation Module (EVM) is a fully-differential, high-voltage piezo actuator driver that provides quick response time for single layer and multi-layer piezo actuators. The DRV8662 drives piezo loads up to 200V differentially using an adjustable integrated boost converter. The evaluation module contains the DRV8662 piezo haptics driver, a programmable MSP430, and passive components …

The DRV8840 evaluation module consists of a 5.0A, single-H-bridge motor driver with a Phase/Enable control interface and a small number external components that can be used to drive a single brushed DC motor. The on-board MSP430 MCU + software/GUI provides signaling and control and supports PWM speed control. With the DRV8840EVM, designers can quickly and easily evaluate the performance of DRV884…

The DRV8843 provides an integrated motor driver solution for printers, scanners, and other automated equipment applications. The device has two H-bridge drivers, and can be used to drive two DC motors, one stepper motor, or other loads. The output driver block for each consists of N-channel power MOSFET’s configured as H-bridges. The DRV8843 can supply up to 2.5-A peak or 1.75-A RMS output curren…

The DRV8601 ERM/LRA driver evaluation module is a complete, low-power and ultra-fast turn-on driver for Eccentric Rotating Mass (ERM) and Linear Resonant Actuator (LRA) types of haptic actuators using a single-ended PWM input signal.

With a fast turn-on time of 100 µs, the DRV8601 is an excellent haptic driver for use in mobile phones and other portable electronic devices.

This evaluation board has been developed for ROHM’s H-Bridge driver customers evaluating the BD62x2FP series. The BD62x2FP series can operate across a wide range of power supply voltages (from 3V to 32V max), supporting output currents of up to 2A. PWM signal control (20 kHz-100 kHz) or VREF control modes are used to vary motor rotation speeds.
