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

(BA6819AF).
