Cordless drill evaluation board information based on

Power MOSFET and 8-pins MCU

Features

chopper).

Description

This STEVAL-IHM012V1 evaluation board

employs a traditional design that illustrates how

the chopper circuit controls a brush DC motor with

a microcontroller as a driver. The purpose of the

board is to demonstrate an ST solution for low-

end cordless power tools, such as cordless drills

or screwdrivers, but can be an ideal starting point

for the design of any application where driving a

low voltage DC brush motor is required. Based on

a Power MOSFET and microcontroller, the

electronic driver is a simple, cost-effective solution

for designers.
