5 / 9 page  Pin Functions Pin No. Pin Name Pin Voltage Equivalent Circuit Pin Function 1VCC Supplies power to all circuits except output block. 2R1 Sets the C pin charge/discharge current. In current limiter operation when the motor is locked, the charge current set by this pin becomes charge current ICL1 for the C pin. 3C Sets the output off time and output current neglect time during current limiter operation. 4R2 Sets the C pin charging current. In current limiter operation when the motor is rotating, the sum of the current set by this pin and the current ICL1 set by the R1 pin becomes charge current ICL2 for the C pin. 5 6 7 OUT1 OUT2 OUT3 Output pin 1 Output pin 2 Output pin 3 8RF Output current detection pin. By inserting resistor Rf between this pin and GND, the output current is detected as voltage. The output current is limited to a current value set by VRF/Rf (current limit operation). 10 VM Power supply pin providing output 9VREG Regulator pin. When using a single power supply (VM), VCC (5.2 V) is supplied by adding an external transistor. The recommended transistor is the 2SD1724T. If a regulator is not used, this pin should either be open or grounded. 11 GND GND for other than output. The minimum potential of output transistor is the RF pin voltage. 12 F/R 0.0 V min VCC max Forward/reverse control pin. 17, 18, 15, 16, 13, 14 IN1 +, IN1– IN2 +, IN2– IN3 +, IN3– 1.5 V min VCC – 1.8 V max Hall device input pin Logic ‘‘H’’ represents IN + > IN–. 19 20 FG2 FG1 Rate pulse output pin 2. Pull-up resistor built in. Rate pulse output pin 1. Pull-up resistor built in. LB1696 No.5244-5/9 |
