L6225PD FAQ

What is DMOS full bridge?

Description. The I.C. is a full bridge driver for motor control applications realized in Multipower-BCD technology which combines isolated DMOS power transistors with CMOS and Bipolar circuits on the same chip.

What is a full-bridge driver?

High-side drivers in turn are designed to drive Q1 or Q3. Half-bridge drivers combine one low- and one high-side driver, so they can drive Q1 and Q2 (or Q3 and Q4) together. Full-bridge drivers obviously have two low-side and two high-side drivers so they can drive all four FETs.

What is a motor driver?

A motor driver takes the low-current signal from the controller circuit and amps it up into a high-current signal, to correctly drive the motor. It basically controls a high-current signal using a low-current signal. There are different types of motor drivers available in the market, in the form of ICs.
