Working Principle of L6498D

The L6498D is composed of threefull bridge gate drivers and a total of six high voltage switches. The full bridge gate driver allows the user to adjust the speed and direction of the stored motor, as well as measure the back EMF (electromotive force) of the motor. The device also provides protection against overheating, currents in excess of 4A, and undervoltage conditions.

The L6498D has a parallel output configuration, with one Pulse-Width Modulated (PWM) output, two Enable (EN) outputs, and two Direction (DIR) outputs. The PWM output is used to provide pulse-by-pulse current up to 4A. The EN outputs are used to enable or disable the full bridge gate driver, and the DIR output is used to control the direction of the motor.

The device also incorporates an omnipolar logic compatible with 1-2 wire bus systems. This allows for the L6498D to be integrated with various other components in the system, such as a communication interface and other drivers.

Lastly, the L6498D provides various protections to ensure safe and reliable operation of the connected motors. These protections include an overcurrent protection, as well as an overheat protection, which prevents the device from overheating during operation.
