BA6407AF
Motor driver ICs
2-phase half-wave motor driver
The BA6407AF is a motor driver dedicated to 12V fan motors. Built-in output transistors reduce the number of external ponents required. The IC has a lock signal output pin. FApplications Fan motors FFeatures 1) Lock detection and rotational speed sensing mechanisms are built in. 2) pact SOP 8-pin package reduces the number of external ponents required. FAbsolute maximum ratings (Ta = 25_C)
3) Automatic restart when the motor lock is undone.
FRemended operating conditions (Ta = 25_C)

FLock detection The automatic restart circuit detects a motor lock condition and automatically turns off the output current. When the lock condition is cleared, the IC automatically restarts and allow the motor to run. In the BA6407AF, automatic restart is performed as...
