55 / 76 page FEDL9058E-01 LAPIS Semiconductor ML9058E 55/76 When Not Using the Internal Power Supply Immediately After Power-on *(a): Enter the power save state within 5ms after releasing the reset state. *(b): Carry out power control set within 5ms after releasing the power save state. The 5ms duration in *(a) and *(b) changes depending on the panel characteristics and the value of the smoothing capacitor. We recommend verification of operation using an actual unit. *(c): When trace resistance in COG mounting does not exist, wait for over 300 ms. Since this value varies with trace resistance, V1, smoothing capacitors, or voltage multiplier capacitors in COG mounting, confirm operation on an actual circuit board when using this LSI. Notes: Sections to be referred to *1: Functional description “Reset circuit” *2: Description of operation “LCD bias set” *3: Description of operation “ADC select” *4: Description of operation “Common output state select” *5: Description of operation “Line reversal/frame reversal drive select” *6: Functional description “Power supply circuit”, Description of operation “Voltage V1 adjustment internal resistor ratio set” *7: Functional description “Power supply circuit”, Description of operation “Electronic potentiometer” *8: Functional description “Power supply circuit”, Description of operation “Power control set” *9: The power save state can be either the sleep state or the standby state.
