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

(BA6819AF).

FApplications

Fan motors

FFeatures

1) Lock detection and rotational speed sensing mecha-

nisms are built in.

2) Alarm output pin (BA6809F) and Hall output pin

(BA6819AF).

3) Built-in thermal shutdown circuit.

4) Operation assured with a supply voltage as low as

2.7V.

5) Compact 8-pin SOP package.
