It is possible to access the register inside of this chip by using the protocol below. Accessing the registers with using this protocol operates LED driver ON/OFF and selecting the mode. Moreover, MAX current can be outputted without Clock input to EN terminal by holding H zone of fixed time after EN terminal starting. < When setting current level > (Notes) TaccMIN < Tpulse < TaccMAX Please input a pulse on this condition < When starting by MAX setup > Fig.5 Register access protocol Fig.6 Slope control example ( Note ) ・ In the case of N > 16, BD1204GWL selects the mode of N = 16. ・ LED current is changed by the pulse of EN pin. Be careful to noise of EN signal. ・ Reset BD1204GWL when the set is unusual. (Keep EN=L over Toff time.) |
