7 / 14 page STK681-332-E No. A1591-7/14 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) Chopping operations based on F3 and F4 are used for current control. The timing given below is used for OUT1 or OUT2 voltage output and for F3 or F4 drain current. (3) Do not connect the N.C pins (5, 11, 12 pin) shown in the internal block diagram or sample application circuit to a circuit pattern on the PCB. (4) Sample Timing Diagram (5) If the current detection resistor, Rs, connected to pin1, pin2, and pin3 is short-circuited, the overcurrent detection circuit does not operate. If the output pin is short-circuited directly to VCC or connected directly to GND, an output short-circuit condition is detected and the output is latched in the off state. To restart the operation, turn on VDD again. (6) Smoke Emission Precautions: There is a possibility of smoke emission if the hybrid IC is subjected to physical or electrical damage as the result of being used without compliance with the specifications. OUT1 or OUT2 Output voltage F3 or F4 Drain current Motor current 22 s 0A GND VCC+Vdf IO peak (current setting value) 0A IO peak (current setting value) Forward rotation Brake Reverse rotation Stop Stop Forward rotation IN1 IN2 ENABLE Stop Brake |
