4-channel BTL driver for CD players
The BA5937AFP is a 4-channel BTL driver developed for use with CD players. In addition to internal drivers for the focus coil, tracking coil, and sled motor, it also contains a driver for the loading motor. FApplications CD-ROM, CD players FFeatures 1) Perfect for pact applications with the use of the HSOP 28-pin power package. 2) Internal thermal shutdown circuit. 3) Gain is adjustable with externally connected resistor. (For channels 1, 3, and 4.) FAbsolute maximum ratings (Ta = 25_C)
4) External mute pin enables the muting of the output current for channels 1 and 4. 5) Power supply is divided into three systems (VCC1 = ch1 and ch4, VCC2 = ch2 and current source, VCC3 = ch3).
