Working Principle of IRS26072DSPBF

The IRS26072DSPBF gate driver receives the low voltage input signal from external logic boards, and then generates high voltage gate drive signals to the individual power stages of the motor driving circuit. The device has 3 inverting inputs for each phase of the motor. When the input signal is low, the output signal of the driver is low, and when the input signal is high, the output signal of the driver is high. This enables the power MOSFETs of the motor driving circuit to be turned on and off at the correct times for energizing and releasing the motor.

The device also regulates the output voltage and current levels to ensure that consistent and reliable operation is possible. The IRS26072DSPBF gate driver includes an adjustable current sink and source capability, as well as an over-voltage and under-voltage lockout protection. This allows the device to be used in a wide variety of applications ranging from automotive to medical device.
