HT7K1201 Single Channel, 6.0V, 1.3A DC Motor H-Bridge Driver

HT7K1201

1 Channel, 6.0V, Peak Current 1.3A H-Bridge Driver

The HT7K1201 is a 1-channel H-bridge driver with a maximum motor peak current of 1.3A. Its outstanding low on-resistance characteristic results in excellent output efficiency which is a major advantage in battery powered systems. A simple two input control pin structure is used to provide four control modes: Forward, Reverse, Brake and Standby modes. With a PWM input control frequency of up to 200kHz, accurate speed control can be implemented for a wide variety of applications. A full range of protection functions are integrated including OCP, OSP and OTP to prevent device damage even if the motor stalls or experiences a short circuit in critical operating environments. As the automatic sleep period activation mechanism uses the same mode control pins, an additional extra shutdown signal is not required. In addition, an ultra-low 0.1uA sleep period current ensures long battery life.
