| 99W122A Single phase full-wave driver IC for fan motor BA6428F Description The BA6428F is a single phase full-wave fan motor driver. It has motor protection functions such as a lock detector, automatic restart, and an output terminal that alarms when the motor is locked. This IC makes sets smaller, due to the compact SOP8 package and the requirement of few external components. Dimension (Units : mm) Features 1) Built-in power Tr 2) Lock detector, Automatic restart function 3) Built-in thermal shut down 4) Alarm output terminal SOP8 Applications Fan motor Absolute Maximum Ratings (Ta=25 C) Parameter Supply voltage Power dissipation Operating temperature range Storage temperature range Symbol VCC Pd Topr Tstg Limits 15 687 -40 ~ -55 ~ * Unit V mW C C +85 +150 * Derating: 5.5mW/C for operation above Ta=25 C.
