A8835EEJTR-T Description

Short technical summary and product information.

The A8835EEJTR-T from Allegro Microsystems is a specialized integrated circuit designed for photoflash capacitor charging applications. It efficiently charges capacitors for digital and film cameras, and also includes an integrated IGBT driver for flash discharge functions, saving valuable board space.

 

Key features include eight-level, digitally-programmable current limits ranging from 550 mA to 1.75 A, allowing operation even at low battery voltages. The device operates from a 3.0 to 5.5 V supply and offers adjustable output voltage with voltage sensing feedback before the output diode for low leakage. It boasts over 75% efficiency and a low quiescent current draw of 1 µA maximum in shutdown mode.

 

This IC is housed in a low-profile, 10-contact 3 mm × 3 mm TDFN package with an exposed thermal pad for enhanced heat dissipation, making it suitable for space-constrained designs. It is lead (Pb) free with 100% matte-tin leadframe plating.

 

Typical applications include digital camera flashes, film camera flashes, cell phone flashes, and emergency strobe lights. The A8835EEJTR-T simplifies designs by integrating the MOSFET switch, transformer driver, and IGBT driver.
