BA6792FP-Y

Optical disc ICs 2-channel BTL driver for CD players BA6792FP / BA6792FP-Y The BA6792FP and BA6792FP-Y are 2-channel BTL drivers for CD player actuator drives. HSOP 28 and 25-pin packages allow for compact applications. FApplications CD players and CD-ROM drives FFeatures 1) 2 channel dedicated BTL drivers. 2) HSOP 28 and 25-pin power packages for compact applications. FAbsolute maximum ratings (Ta = 25_C) 3) Gain is adjustable with an attached resistor. 4) Internal thermal shutdown circuit.

The output current is muted when the chip temperature rises above 175_C (typically). The driver circuit is restored when the chip temperature rises above 150_C (typically). (2) The output current can be muted by opening the mute pin voltage or lowering it below 0.5V. This pin should be pulled up above 2.0V during normal operation. (3) Muting also occurs when the bias pi...
