DC Motor Driver
1.DCM output control logic
2.Current limit control timing chart
3.Setting the current limit value
Braking operation time in current limit mode can be set by connecting a capacitor between SCP and GND pins. This
setting is the same as the time setting required to turn off the outputs when an output short-circuit occurs as explained in
the section entitled "Output Short-circuit Protection Function." See "Output Short-circuit Protection Function," for the
settinig procedure.
The current limit value of the DCM driver is determined by the VREF voltage and the resistance (RNF) connected
across the RNF and GND pins using the following formula :
Assuming VREF = 1.5V, RNF = 0.2Ω, the current limit is :
