Working from a single or dual Li-Ion cell or dual or more AA batteries the TMC7300 is optimally suited for battery operated equipment. Its two full-bridges allow either control of two DC motors, PWM-control of LEDs, or protected standalone peripheral driving, using a polarity signal per halfbridge. Operate up to two DC motors via simple UART control for direction, velocity and torque. Integrated power-MOSFETs with internal charge-pump for best-in-class RDSon even at low supply voltage, handle motor current up to 1.2A per motor continuously, or the double current in parallel connection. Together with a tiny standby current, this guarantees a long battery life. Protection and diagnostic features support robust and reliable operation. This advanced driver ensures efficient and reliable operation for cost-effective and highly competitive solutions.
