   CXMD3286 CXMD3287 CXMD3288 provides an integrated brush DC motor drive solution for battery-powered toys, low-voltage or battery-powered motion control applications. The circuit integrates on-chip H-bridge drive circuit designed with N-channel and P-channel power MOSFETs and is suitable to drive a brushless DC motor or a stepper motor winding. It has the wider operational voltage range (from 2V to 12.0V), its maximum continuous output current is up to 2.6A, and its maximum peak output current is up to 4A.The series circuit powered by VCC and VDD separate , which VCC is logic and control power supply, VDD is power supply. CXMD3286 CXMD3287 CXMD3288 has on-chip temperature protection function. When the load current of the drive circuit is much larger than the maximum continuous current of the circuit, the junction temperature of the circuit will be increased rapidly. Once the set value (150℃) is exceeded, the internal circuit will be closed immediately Off the output power tube, cut off the load current, to avoid the temperature continued to rise caused by plastic packaging smoke, fire and other security risks. Built-in temperature hysteresis circuit to ensure that the circuit is restored to a safe temperature before allowing the circuit to be re-controlled. CXMD3286 CXMD3287 CXMD3288 set a separate current sampling output pin, sampling output current sampling ratio of 1000: 1. The output sampling current for MCU analysis or control the external circuits to control the output current.
