If you buy micro dc motor， what are the current limits of the motor?
1. The external inverter bridge of 24V DC motor is grounded by a resistor Rs for current sampling, and the sampling voltage is input to the current detection comparator.
2. The comparator inverting input is set with a 100mV reference voltage as a current limit reference.
3. During the rising period of the oscillator sawtooth wave, if the current is too large, the comparator flips, so that the lower Rs trigger is reset, and the drive output is turned off to limit the current to continue to increase.
4. At the sawtooth fall time, set the trigger again to turn the drive output on.
