Smartburster brake system and pre-driver applying the same

摘要

A smart booster braking device and a pre-driver applied thereto are provided. This smart booster braking apparatus can include a pre-driver including a stabilizing circuit portion including two transistors, so that the 12V power supply can be stably supplied even in a period where the load voltage rises, Is ensured and a stable output of the upper and lower switches is ensured. As a result, even if there is a ripple component and disturbance of the power source due to the load fluctuation, the output of the pre-driver, that is, the upper and lower stage switch waveforms (PWM waveform) can be supplied stably without any distortion so that the motor control is stabilized and the reliability and robustness of the smart booster braking device .
