MX1515 - Brushed DC motor drive circuit
Description
This product provides an integrated brushed DC motor drive solution for battery-powered toys, low-voltage or battery-powered motion control applications Program. The circuit integrates two channels of H-bridge drive circuit designed with N-groove and P-groove power MOSFETs, which is suitable for driving electric toy cars Steering wheel and rear wheel drive. The circuit has a wide operating voltage range(from 2V to 9.6 V),and the maximum continuous output current of the steering wheel drive is up to To 1.5 A,the maximum peak output current reaches 2.5 A,the maximum continuous output current of the rear-wheel drive reaches 1.5 A,and the maximum peak output current reaches 2.5 A. The drive circuit has a built-in overheating protection circuit. When the load current through the drive circuit is much larger than the maximum continuous current of the circuit, the heat dissipation energy of the package is affected Once the set value (typical value 150℃) is exceeded,the internal circuit will immediately turn off the output power
rate tube, cut off the load current,to avoid the continuous increase in temperature caused by plastic packaging smoke, fire and other safety risks. Built-in temperature hysteresis circuit, to ensure After the circuit is restored to a safe temperature, it is allowed to re-control the circuit.
