Motor driver ICs
Fan motor driver IC
BA6817F / BA6818FS
The BA6817F and BA6818FS are 24V motor drivers for 2-phase, half-wave fan motors. The ICs have lock detection
and automatic restart functions. In compact SOP8 (BA6817F) and SSOP-A16 (BA6818FS) packages, the ICs reduce
the number of external components required.
Applications
2-phase motors such as fan motors
Features
1) Built-in power transistors.
2) Lock detection and automatic restart functions.
3) Thermal shutdown circuit.
Absolute maximum ratings (Ta = 25C)
4) Alarm output pin. (BA6817F / BA6818FS)
5) Hall signal output pin. (BA6818FS)
