Product details

Description

The Allegro® A8437 Xenon photoflash charger IC is designed to meet the needs of ultra-low power, small form factor cameras, particularly camera-phones.

Features

Low quiescent current draw (0.1 μA in shutdown mode).
Primary-side output voltage sensing; no resistor divider required.
User-adjustable current limit from 0.4 to 1.2 A.
1.1 V logic (VHI(min)) compatibility.
Integrated IGBT driver with separate sink and source (CG package) or common sink/source (EJ package).
Flash dual trigger with interlock for increased noise immunity.
Optimized for mobile phone, 1-cell Li+ battery.
