4 / 6 page 715 Motor driver ICs BA6811F / BA6813F FCircuit operation The BA6811F and BA6813F have motor lock detection and automatic restart circuits. The timing of lock detec- tion and automatic restart is determined by the external capacitor connected to the LD pin. The charge time of the external capacitor is given by : (Typical value) where VLDCL is the LD-pin clamp voltage (1.93V), VLDCP is the LD-pin comparator voltage (0.76V), ILDC is the LD-pin charge current (2.9 µA), ILDD is the LD-pin discharge current (0.52 µA), C is the capacitance of the LD-pin external capacitor. For C=1 µF, for example, the charge (output ON) and dis- charge (output OFF) times are 0.40s and 2.25s, respec- tively. The timing chart for an occasion of motor locking is shown in Fig. 1. ILDC TON (Charge time)= C S (VLDCL*VLDCP) ILDD TOFF (Discharge time)= C S (VLDCL*VLDCP) |
