(typ.). the hysteresis is set to 25
(typ.), so the circuit will start up again when the chip temperature falling to 150
(typ.). 2) in case mute pin voltage is under 0.5v or nc, output current is muted (except tw o dc-dc converter). mute pin voltage should be more than 2.0v for normal application. 3) in case en pin voltage is under 0.5v or nc, the conv erter circuit will stop operation. en pin voltage should be more than 2.0v for normal application. 4) bias pin (pin 34) should be pulled up to more than 1.2v. in case the bias pin voltage is pulled down below 0.9v (typ.), the output current of 4-channel btl is muted. 5) heat dissipation fins are attached to the gnd on the insi de of the package. make sure to connect them to the external gnd. 6) dc-dc step down converter: please refer to application note. 7) truth table of mute, en1, en2 truth table ( : active : inactive -- : don?t care ) mute en 1 en 2 motor channel dc-dc ctrl i dc-dc ctrl ii h -- -- -- -- -- h -- -- -- -- -- h -- -- l l l www.datasheet.co.kr datasheet pdf - http://www..net/
