4-channel BTL driver for CD players

ROHM Semiconductor 

Optical disc ICs

FOperation notes

(1) The BA6297AFP has an internal thermal shutdown

circuit. Output current is muted when the chip tempera-

ture exceeds 175_C (typically).

(2) If the mute pin (pin 15) voltage is opened or lowered

below 0.5V, the output current will be muted. Pin 2 should

be pulled up above 2.0V during normal use. During mut-

ing, the output pins remain at the internal bias voltage,

roughly (VCC*VF) / 2.

(3) Be sure to connect the IC to a 0.1µF bypass capaci-

tor to the power supply, at the base of the IC.

(4) The radiating fin is connected to the packages inter-

nal GND, but should also be connected to an external

ground.
