AS3636 Preliminary Datasheet, Confidential Xenon Driver IC with LED Driver and Life Time Counter 1 General Description The AS3636 is a highly integrated photoflash charger including IGBT driver, inductive DCDC boost autofocus/ video LED driver, an indicator LED driver and it includes system level ESD protection and a breakable fuse. The AS3636 includes flash timeout, over- and undervoltage, overtemperature and LED short circuit protection functions. To reduce production test time a broken transformer or a broken coil is detected. The AS3636 is controlled by an I2C interface with a dedicated STROBE input. Additionally the TORCH input controls the torch function. An interrupt output is available to signal an error condition to the controller. The device includes 11 Bytes EEPROM, and an automatic life time counter to count the number of flashes performed. The AS3636 is available in a space-saving WL-CSP package and operates over the -30ºC to +85ºC temperature range. Warning Lethal voltages are present on applications using AS3636! Do not operate without training to handle high voltages.
