General Description
The HT7K1211 is a 1-channel H-bridge driver with a
maximum motor peak current of 2.1A. 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/Sleep modes.
With a PWM input control frequency of up to 200
kHz, 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 mode activation
mechanism uses the same mode control pins, an
additional extra shutdown signal is not required.
In addition, an ultra-low 0.1μA sleep mode current
ensures long battery life. The device also includes
separate power supplies for the control circuits and
the motor power supply and also includes a current
sensing pin to allow the system to measure the motor
current using an external resistor.
