General Description
OB6606 is a monolithic, high performance, low cost brush motor controller，which requires only a few BOM to complete system.
OB6606 integrates high performance MCU, power MOS driver，high-resolution 5V regulator, high-speed rail-to-rail amplifier, comparator for over current protection(SCP). OB6606 provides higher flexibility, lower volumn and lower cost motor control system.
OB6606 supports the development of the control program, integrates single PWM driver and current detection, provides 14 GPIOs, 4-channel PWM, 8-channel ADC, UART interface etc. It meets the needs of most brush motor applications.
OB6606 provides protection functions to improve stability of symtem application, includingunder voltage lockout, over voltage protection, over temperature protection, over current protection.
