5 / 10 page STK681-300 No. A0760-5/10 Motor Drive Conditions (H: High-level input; L: Low-Level Input) IN1 IN2 INH Remarks Stop 1 (standby) H H H or L When motor is not rotating H H H H L H Stop 2 (supply power turned off by input during motor rotation) L H H Stop signal that is applied when the motor is running and used to turn off power. Forward (CW) H L L Reverse (CCW) L H L No input signal is needed that turns off the upper- and lower-side drive devices when switching the rotational direction. Brake L L L or H GND side MOSFET ON * IN1=IN2=H and INH=L are prohibited during motor rotation. Notes (1) Be sure to set the capacitance of the power supply bypass capacitor, C1, so that the ripple current of the capacitor, which varies as motor current increases, falls within the allowed range. (2) Although the Vref2 pin is kept open, if connected to the GND or S.P pin, the overheating current control circuit ceases to function. (3) Fixed current chopping operations based on TR1 and TR2 are used for current control. The timing given below is used for OUT1 or OUT2 voltage output and for TR1 or TR2 collector current. (4) Do not connect the N.C pins shown in the internal block diagram or sample application circuit to a circuit pattern on the PCB. (5) This IC is not designed for use in an H-bridge driver for power supplies because the I/O response time of its GND side driving device, required when switching the motor rotational direction, is several scores of microseconds. It should be used only for DC motor drivers. OUT1 or OUT2 Output voltage TR1 or TR2 Collector current Motor current 50 μs 0A GND VCC1-Vsat1 IO peak (current setting value) 0A IO peak (current setting value) |
