The CST6307 is a motor drive for brushed DC that can operate from 6.5V to 25V, providing up to 3.6A peak current. The CST6307 integrates a current modulation circuit to set the operating current according to the VREF and the resistance external to the ISEN. A simple PWM interface can realize the connection and control of the controller.
    The CST6307 can enter low-power sleep mode when the system does not require a drive motor.
    The CST6307 provides an internal shutdown function for UVLO and overheat protection.
    The CST6307 is a brushed DC motor driver for high-current toys, robots, printers, POS machines, appliances and other small machines. Two logical inputs control the H-bridge driver, which consists of four n-channel metal-oxide-semiconductor field-effect tubes (MOSFETs), capable of bidirectional control of the motor at peak currents up to 3.6A. Using the current attenuation mode, the motor speed can be controlled by pulse width modulation (PWM) of the input. If these two inputs are set to low, the motor driver will enter low-power sleep mode.
    The CST6307 features integrated current regulation based on the analog input VREF as well as the voltage of the ISEN pin (proportional to the motor current flowing through the external sensing resistance). The device is able to limit current to a certain level value, which can significantly reduce system power requirements, and does not require large capacity capacitors to maintain a stable voltage, especially when the motor is started and stopped.
    The CST6307 integrates various protection functions to achieve internal shutdown function in case of failure, providing undervoltage locking and overheat protection. In addition, a low-power sleep mode is provided.
    The CST6307 is available in an e-SOP8 package with heat sink.
