Reversible Motor Driver
1)Wide operating voltage range : 6.5~34V
2)Can be operated directly by TTL and CMOS
3)Low power consumption while the motor is stopping
due to built-in power save circuit
4)Output high voltage can be set externally by VREF pin.
5)Built-in surge absorbing diode
6)Built-in TSD (Thermal shut down ) circuit
7) A signal ground and a power ground are provided
separately, so that reversible/variable speed control
is available by adding an electronic governor.
The BA6920FP-Y is an IC for small DC motor
drive which has a wide operating voltage range.
It has four output modes such as forward, reverse,
stop and brake. When the motor is stopped, all
circuits turn off automatically. A power save circuit
that reduces current consumption and a power save
terminal is included. This IC has 34V maximum
operating voltage, so that it is useful for wide
varieties of applications.
