s BA6832FS FInput / output circuits 511 Motor driver ICs FElectrical characteristics (unless otherwise noted, Ta = 25_C and VCC = 12V) BA6832FS 512 Motor driver ICs FCircuit operation (1) Output current control The method of output current control depends on whether the RTL pin is HIGH or LOW.
(1) When the RTL pin is LOW The voltage VRS that develops across the resistor RS between pins 10 and 11 (with reference to pin 10) is controlled by the voltage between Vctl (pin 18) and Vref (pin 19) : VRS=(Vctl*Vref) 1 (Typ.) The output current IO is given by : IO=(Vctl*Vref) / Rs (Typ.) where the positive direction is from pin 13 to pin 10.
Therefore, the voltage-current conversion gain for the control input is determined by the RS value.
