Figure 6. Xenon Charging Flowchart

Upon setting of CHARGE (see page 26) or CAR, VOUTBOOST is boosted to 5V

started. Once finished, charging is stopped (CHARGE is reset), READY and READYF s set and the interrupt line INT

is pulled low (if not disabled by READYFI). Upon STROBE

Upon release of STROBE and if the register bit CAR

Every second flash cycle, the internal life time counter(xenon_life_counter_MSB and xenon_life_counter_LSB) inside

the EEPROM (see EEPROM Writing Cycle on page 13) is updated to count the number of flash for the attached Xenon

tube.

If no flash is triggered for CAR_interval time (can be set between 1.0s to 4.5s) and CAR = 1, the capacitor is automati-

cally recharged.
