Motor driver ICs
2-phase half-wave motor driver
BA6809F / BA6819AF
The BA6809F and BA6819AF are motor drivers designed for 3V and 5V fan motors. Built-in output transistors reduce
the number of external components required. The ICs have an alarm output pin (BA6809F) and Hall output pin
1) Lock detection and rotational speed sensing mecha-
nisms are built in.
2) Alarm output pin (BA6809F) and Hall output pin
3) Built-in thermal shutdown circuit.
4) Operation assured with a supply voltage as low as
5) Compact 8-pin SOP package.
FAbsolute maximum ratings (Ta = 25_C)
