S/S _{Start with L and stop with H or in the open}
condition
12
V_CC Control circuit power pin
13 GND1 GND pin (control circuit block)
VCC
Equivalent circuit
3.5 kΩ
11
Pin to set the PWM oscillation frequency.
14 PWM
Connect a capacitor between this pin and GND.
200 Ω

VCC
PWM waveform comparator pin.
Normally use with “L” or open. To control the
15 TOC _{output duty by applying the voltage to this pin}
without using the PWMIN pin, set the PWMIN pin
to “L”.
VCC
Pin to set the operation time of motor lock
protection circuit.
16 CSD _{Insertion of a capacitor (about 10 µF) between}
CSD and GND enables setting of the protection
operation time of about 3.5 sec.
