Reversible Motor Driver  
BA6920FP-Y  
Description  
Dimension(Units:mm)  
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.  
HSOP25  
Features  
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.  
Applications  
VCR, Audio system applications, Office automation equipment, Industrial applications
