Electrical Characteristics

Figure 8. Power Dissipation vs. Ambient Temperature

Figure 9. Control Timing Diagram of AM4406 OFF time are determined by the capacitance of C2. Note 5: RD pin is ON during normal operation, and OFF when the motor is locked. It is an open collector output pin. Note 6: The RD pin may maintain HIGH level for a few hundred milliseconds when the power is turn on.
