6. PROTECTION FEATURES

● Overcurrent Protection with Active Current Limiting

When the motor is trying to draw more current than what the motor driver can supply, the

PWM to the motor will be chopped off and the motor current will be maintained at

maximum current limit. This prevents the motor driver from damage when the motor stalls

or an oversized motor is hooked up. OC LED will turn on when current limiting is in action.

● Temperature Protection

The maximum current limiting threshold is determined by the board temperature. The

higher the board temperature, the lower the current limiting threshold. This way, MD25HV

is able to deliver its full potential depending on the actual condition without damaging the

MOSFETs.

● Undervoltage Shutdown

The motor driver output will be shut down when the power input voltage drops below the

lower limit. This is to make sure the MOSFETs have sufficient voltage to fully turn on and do

not overheat. ERR LED will turn on during undervoltage shutdown.
