MP86956 FAQs
A half-bridge driver is a circuit used to control the movement of a motor or other load. It converts the supply voltage to a voltage suitable for the load and provides the necessary current. This type of driver is commonly used for DC motors, stepper motors, and other loads that require precise control.
The half-bridge driver realizes the speed and steering control of the motor by controlling the on and off of the two switching tubes (M1, M2). The control signal can also be PWM modulated.
The MP86956 monolithic half-bridge chip is a highly integrated, high-performance half-bridge driver chip with the following characteristics:
High integration: Integrates all functional modules required for the half-bridge drive circuit, such as input logic control, dead time control, power supply, etc., greatly simplifying circuit design.
High performance: It has fast response speed and low noise performance, and can provide accurate driving signals to ensure the stable operation of motors or other loads.
Convenient motor control: Supports PWM (pulse width modulation) and complementary PWM control methods to facilitate control of motor speed and direction.
Complete protection functions: Built-in over-current protection, over-temperature protection and other protection functions ensure that the chip can automatically protect and prevent damage under abnormal circumstances.
