Drive chip with brushless DC motor The most one H-bridge driver chip: L928N This chip is very simple, very cheap, and easy to buy, a chip inside the integration of DC brushless motor driver chip a 2-way H-bridge circuit, but also with PWM control and current acquisition. However, it has two serious disadvantages: 1) The manual requires the motor drive voltage to be 5V higher than the control logic voltage. Not suitable for single power supply car. 2) The loss on the H-bridge circuit is too great.
With a triode, or MOS tube, mainly depends on the size of the working current, or the powerSize. If the power is very small, you can also use the chip, but you can not use ordinary logic chips, such as 74 series chips are generally not available, you can use a power driver chip like ULN2003, of course, the premise is that the drive power is enough.
v DC motor drive, current less than 3A can use l298N, current less than 43A can use BTS7960. The L298N chip is equipped with dual H-bridge motor drivers, each H-bridge can provide 2A current, the power supply voltage range is 5-48v in the power supply part, the logic part is 5v power supply, and accepts 5vTTL levels=' The chip that drives the brushless DC motor? '> The chip that drives the brushless DC motor?
1, its DC brushless motor can be adapted to a variety of applications from air conditioning fan motors to PC cooling fans. 2, reduce the number of external components, reduce the cost because it is equipped with analog voltage comparator, CR oscillation circuit, voltage detection circuit, monitoring timer circuit, no need to add external oscillator, reset IC, help to reduce system costs.

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, I also have a problem with this question... At present, I have found a more suitable chip IR2110/IR2103, these two are similar, and MC3303MC3303LMD18200.
4, the high voltage motor drive circuit is composed of ML4425 as the core to drive the high voltage motorThe actual circuit. The power drive circuit of the circuit is composed of six high-power MOS Fets and three IR2118 front driver chips, which can drive the forward rotation, reverse and brake of the motor.
1, 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, PSuch as IC16F73.
2, OCV3280B is a sensorless brushless DC motor drive control chip, it integrates motor controller and driver, can achieve 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.
3, its DC brushless motor can be adapted to a variety of applications from air conditioning fan motors to PC cooling fans. 2, reduce the number of external components, reduce the cost due to the analog voltage comparator, CR oscillator circuit, voltage detection circuit, monitoring timer circuit, no need to add an external oscillator, reset IC, help to reduce system costs.
4, there are more types of driver chips on the market at present, if it is the driver chip and MCU integration of the driver there are several chip manufacturers have similar products, you can find ON Mei (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.
5, functional features ML4425 is an intelligent brushless motor special controller introduced by Micro Linear, which can be used to provide closed-loop commutation control signals for three-phase brushless motors, while using PWM mode to control motor speed and provide necessary protection for the motor.
6, Hall components of the induction signal feedback control of its oscillation frequency and phase and then control the speed, the principle is simple, the actual control is more complex, you can refer to AN383BA6840 and other chip feedback control. In most brushless DC motor control applications with sensors, Hall effect sensors are used to determine rotationThe sub-position. The Hall effect sensor is located in the motor housing, and the output state of each sensor changes once every certain electrical Angle.
FT8215, GC4931F/S, XM2618 chip, etc.
Its DC brushless motors can be adapted to a variety of applications from air conditioning fan motors to PC cooling fans. 2, reduce the number of external components, reduce the cost due to the analog voltage comparator, CR vibrationSwing circuit, voltage detection circuit, monitoring timer circuit, no need to add an external oscillator, reset IC, help to reduce system costs.
BP6308A, CS5755MT. BP6308A is a high-performance and low-cost three-phase brushless DC motor sine wave control chip, which integrates Hall position decoder, MOSFET driver, oscillator and other modules. The CS5755MT is a highly integrated, highly reliable three-phase brushless DC motor drive circuit for use in lower power motor drives such as fan motors.
The kinds of driver chips currently on the marketMore analogy, if it is the driver chip and MCU integration of the driver there are several chip manufacturers have similar products, you can find ON Mei (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.
ML4428 Normal power supply is 12V, when the power supply is lower than 75V, all 6 output drivers will be turned off.
Do you use ULN2003 or IR2110? How useful it is. taobao.comA lot of them. As for what you're talking about, I don't know. Maybe you typed in the wrong model number. I haven't seen anything about it on Baidu.
