The A8835EEJTR-T from Allegro MicroSystems is a sophisticated integrated circuit engineered for photoflash capacitor charging applications, commonly found in digital and film cameras, cell phones, and emergency strobe lights.
This IC integrates a MOSFET switch for driving a transformer in a flyback topology and includes an IGBT driver to facilitate the flash discharge function, thereby saving board space. A key feature is its eight-level, digitally-programmable current limit, adjustable from 550 mA to 1.75 A by clocking the CHARGE pin. This allows for flexible operation, even at low battery voltages.
The A8835EEJTR-T operates from a 3.0 to 5.5 V supply (VIN and VBIAS) and can be powered by one Li+ or two Alkaline/NiMH/NiCAD batteries. It offers high efficiency of over 75% and a low quiescent current draw of 1 μA maximum in shutdown mode. The device provides charge complete indication via the DONE pin.
Packaged in a low-profile (0.75 mm high) 3 mm × 3 mm 10-contact TDFN package with an exposed thermal pad, the A8835EEJTR-T is ideal for space-constrained designs. It is lead (Pb) free with 100% matte-tin leadframe plating.
