2-channel BTL driver for CD players
BA6295AFP
The BA6295AFP is a 2-channel BTL driver for CD player actuators and motors. This IC delivers a large output current
and is ideal for car CD players.
FApplications
CD players
FFeatures
1) 2-channel BTL driver.
2) High output current. (Io = IA Typ.)
3) HSOP 28-pin package allows for miniaturization of
applications.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)
4) Internal thermal shutdown.
5) Gain is adjustable by inserting a resistor between
pins 27 and 28 ; pins 18 and 16.
