MX1508 SOP-16 Four-Channel Dual Brushless DC Motor Driver IC
The product provides an integrated brushless DC motor drive solution for battery-powered toys, low-voltage or battery-powered motion control applications
case. The circuit integrates two channels of N-channel and P-channel power MOSFET design of the H-bridge drive circuit, suitable for driving electric toy car steering
Wheel and rear drive, (drive brushless DC motor or drive two stepping motors). The circuit has a wide operating voltage range (from
2V to 9.6V), the maximum continuous output current of the steering wheel reaches 0.8A, and the maximum peak output current reaches 1.5A. Rear wheel drive maximum continuous output power
Flow reaches 1.5A, the maximum peak output current reaches 2A.
The drive circuit built-in thermal protection circuit. Through the drive circuit load current is much greater than the maximum circuit current, by the package cooling capacity
Limit, the internal chip chip temperature will rise rapidly, once more than the set value (typical 150 °C), the internal circuit will immediately turn off the output power
Rate, 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, indeed
After the circuit is restored to a safe temperature, the circuit is allowed to be re-controlled.
