CS2018 integrates Hall voltage generator, differential amplifier, Schmidt flip-flop and open-collector output stage, etc., which can directly drive low-power motor windings, and the pin is only 4 pins, and the optical drive is useful to BA6849, and BA5954.
The current more suitable chip I found IR2110/IR2103, these two are similar, and MC3303MC3303LMD18200.
If it is the driver chip and MCU integration of the driver there are several chip manufacturers have similar products, you can find ON (8824) and Allgro these two, there are drivers that meet your application requirements. If some complex control functions are needed, the special chip may not be able to meet the requirements, and the single chip microcomputer is needed for product design.
Cheap DC brush driver chips canFor similar products, you can find On (8824) and Allgro, which have driver chips that meet the requirements of your application. If some complex control functions are needed, the special chip may not be able to meet the requirements, and the single chip microcomputer is needed for product design.
3, electric vehicle DC brushless motor controller used M333033, MC33035 and so on, in addition to some is the use of single-chip control such as AT89C2051, PIC16F72, PIC16F73 and so on.
4, brushless motor is usually designed for three-phase motor, soThe chip that can output time-sequence three-phase excitation signal is likely to be used as the core driver chip of brushless motor. The simple brushless fan motor has only two phases and its control core is to use the Hall element to guide a transistor to start and switch by detecting the position of the magnetic pole.
5, ML4425 is an intelligent brushless motor controller special circuit introduced by MicroLinear company. This circuit provides all the functions needed to start and control Delta and Y windings, speed of brushless motors, and commutation.
This should be combined with the specific needs to make a difference, if only to do some low-voltage and small current square wave drive, some chips are both applications can meet, but if you want to do some complex brushless applications, especially the FOC drive mode, the need for computing resources is more, the general MCU can not meet.
The difference between brushed and brushless is very different. The brush is much simpler, and it can be turned by giving a DC voltage. Brushless requires power electronics to turn on and offOff voltage, and need to judge the rhythm of the switch according to the position of the rotor, the control requirements are more complex.
Rotor structure is different: the rotor of the brushed DC motor is usually composed of a series of iron cores wrapped with copper wire, and the electromagnetic conversion between the rotor and the stator is realized through the cooperation of the brush and the motor controller.
Different structure composition Different DC brushless motors are composed of the motor body and the driver, the stator windings of the motor are made of three-phase symmetrical star connection, and the driver is composed of power electronics and integrated circuits. The components of the basic structure of DC brush motor include stator, rotor,Brushes and commutators.
Different mode of operation Brush motor refers to the motor is a direct current input, control its controller, only to provide it with the size of the current can be adjusted.

Feng 岹 Technology Shenzhen Co., Ltd. was established on May 21, 2010, legal representative: BI LEI, registered capitalBook: 9,2334 yuan, located at Room 203, Building 11, Shenzhen Software Park (Phase 2), No. 1, Keikezhong 2 Road, Gaoxin Central District, Nanshan District, Shenzhen City (office only).
1, ocv3 test is optical character verification. Optical Character Validation, or OCV, is a machine vision software tool used to check the print or labeling quality of optical character recognition OCR strings and confirm their legibility.
2, refers to the insulation of the motor and the heat resistance grade of the insulation material used.
3, belongs to the grounding fault, check whether the motor line is damaged ground cause analysis: grounding protection line action, when the AC motor driver detects that the output terminal is grounded and the grounding current is greater than 50% of the rated current of the AC motor driver, it should be noted that this protection is for the AC motor driver rather than the human body.
OCV3280B is a sensorless brushless DC motor drive control chip, it integrates motor controller and driver, can realize brushless motor control and drive, is the ideal electric vehicle motor drive control chip. OCV3280B adopts PWM four-quadrant drive mode, which can realize the positive and negative control of the motor and speed control.
