Photoflash Capacitor Charger for DSC
Feature
Description
2.9V to 5.5V Supply Voltage Operating Range.
Adjustable Output Voltage.
The G2109 is a charger IC for Photoflash capacitor with
soft-start function, an IGBT driver for igniting flash tube,
adjustable output voltage and adjustable primary peak
current to perform energy transition on each charge cycle.
The output voltage is determined by voltage divider
connecting to the anode of the rectifying diode. The
voltage sensing path is cut off when charging function to
be completed to maintain minimum output voltage decay.
It also provides SCP function for the voltage divider open
or output short.
Adjustable Peak Current.
Charge Complete Indicator.
Built-in IGBT Driver.
Built-in Slow Charge Function.
Thermal Protection
Built-in Output Short Circuit Protection
Charges Any Size Photoflash Capacitor.
Small 10-lead DFN Package.
Application
Digital / Film Camera Flash
PDA / Cell Phone Flash.
