The HT7K1211 is a 1-channel H-bridge driver with a maximum motor peak current of 2.1A which is specifically used in a wide range of products such as electronic locks, electronic valves, toys, etc.
As these highly functionally integrated devices have the feature of low on-resistance power transistor, their efficiency is much improved resulting in reduced device temperature allowing operation over a larger ambient temperature range.
Two input control pins provide four modes of operation, Forward, Reverse, Brake and Standby / Sleep. The PWM input control frequency can be up to 200kHz making it useful for accurate speed control 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 0.1μA sleep period current ensures long battery life.
