LB11948T - Monolithic Digital IC PWM Constant Current Control 1-2 Phase Excitation Stepping Motor Driver

Output Output Unused Unused Lower side internal diode anode connection Constant current control sensing The motor current is set by the value of the sensing resistor Re connected between the E1 pin and ground. The current is set according to the following equation: IO = VREF/Re (A) VS power supply .
