Motor driver ICs
Reversible motor driver
BA6222
The BA6222 is a reversible-motor driver with a maximum output current of 2.2A. Two logic inputs allow four output modes: forward, reverse, idling, and braking. The motor revolving speed can be set arbitrarily by controlling the voltage
applied to the motor.
Applications
VCRs
Features
1) Large output current. (I
2) Built-in thermal shutdown circuit.
3) Output voltage can be adjusted arbitrarily with the
output voltage setting pin. Because the pin has a gain
of 11.4dB, a high output voltage can be set with a low
input voltage.
