Motor drive series L298N

  L298N
L298N is a special drive integrated circuit and belongs to H-bridge integrated circuit
The difference between L298N and L293D is that the output current increases and the power increases
Its output current is 2a, the maximum current is 4A and the maximum working voltage is 50V
It can drive inductive loads, such as high-power DC motor, stepping motor, solenoid valve and so on
In particular, its input end can be directly connected with the single chip microcomputer, so it can be easily controlled by the single chip microcomputer
When driving the DC motor, the stepping motor can be directly controlled, and the forward rotation and reverse rotation of the motor can be realized
To realize this function, only the logic level of the input terminal needs to be changed
In order to avoid the interference of the motor to the single chip microcomputer, this module adds an optocoupler for photoelectric isolation, so that the system can work stably and reliably

L9110S
L9110 is a dual channel push-pull power amplifier special integrated circuit device designed for controlling and driving motors
It integrates discrete circuits into a single-chip IC to reduce the cost of peripheral devices and improve the reliability of the whole machine
The chip input is compatible with TTL / CMOS level and has good anti-interference performance; The two output terminals can directly drive the motor to move forward and backward
It has large current driving capacity
Each channel can pass 800mA continuous current, and the peak current capacity can reach 1
5A; The built-in clamping diode can release the reverse impulse current of inductive load, making it safe and reliable in the use of driving relay, DC motor, stepping motor or switching power tube
The chip is integrated with thermal shutdown protection function module
When the chip PN junction temperature exceeds the design threshold, all circuit module functions will be turned off
L9110 can be widely used in toy car motor drive, stepping motor drive, switching power tube and other circuits

L7010R
L7010r is an H-bridge integrated circuit device of two channel power MOSFET designed for controlling and driving DC motor
