Description
The G2132 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 ...
