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).

FEATUREs
1) Lock detection and rotational speed sensing mechanisms 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.

APPLICATIONs
    Fan motors
