Type of Motor

Nearly half of the world's power consumption is consumed by electric motors, so the high efficiency of electric motors is considered the most effective measure in solving the world's energy problems.

QFN Packaging of Flip Chip in Motor Drive

Flip chip QFN (FCQFN) packaging is similar to conventional QFN packaging, but its chips are directly connected to the board at the bottom of the device in an inverted manner, rather than using bonding

QFN and TSSOP Packaging for Motor Drivers

The TSSOP package is rectangular and uses two rows of pins. The TSSOP packaging of motor driver ICs usually has a large exposed board at the bottom of the packaging to remove heat from the device. TS

Layout of Motor Driver Capacitors

The component layout guidelines for motor driver ICs are similar to other types of power ICs. The bypass capacitor should be placed as close as possible to the device power pin, while the large capaci

Heat Dissipation of the Motor-Through-Hole

Through holes are small electroplated holes typically used to thread a wire from one layer to another. Although hot through holes are made in the same way, they are used to transfer heat from one laye

Heat dissipation of the motor-Line

Due to the presence of wiring and components, the heat dissipation of double-layer PCBs may be more difficult. Therefore, it is necessary to provide as many solid copper surfaces as possible and achie

The Field-effect Transistor Output Part of the Motor

There is a diode in reverse parallel between the source and drain inside the high-power field-effect transistor. When used as an H-bridge, it is equivalent to having four diodes in parallel at the out

Input and Level Conversion Part of the Motor

The input signal line is introduced by DATA, with pin 1 being the ground wire and the rest being the signal lines. Note that a 2K ohm resistor is connected to the ground on pin 1. When the driver boar

Design Objectives of DC Motor Drive Circuit

In the design of DC motor drive circuits, the following points are mainly considered: Function: Does the motor rotate in one direction or two directions? Do you need to adjust the speed? For unidirec
