LOCK DETECT CIRCUIT, AUTOMATIC RESTART CIRCUIT

Charge and discharge time at motor lock condition varies with the value of external capacitor at LD terminal, and is

given by the following equation.

C×(VLDCL-VLDCP)

TON (Charge time) =

ILDC

C×(VLDCL-VLDCP)

TOFF (Discharge time)=

ILDD

C: Capacitor at LD pin

The following value shows charge time and discharge time at C=0.47µF for reference.

Charge time =0.18S (Output: ON)

Discharge time = 1.02S (Output: OFF)
