Part Number : 8602GN, OZ8602GN
Function : Battery Charge Controller
Package : SOP 16 Pin

DESCRIPTION
iC-LQNP is a sensor for pulse and alternating light with a monolithically integrated photodiode. The device supersedes conventional photoreceivers, such as those in light barriers, for example.
Changes in the photocurrent are amplified whereas the photocurrents caused by background light are electronically suppressed with over 60 dB (at 100 Hz).

♦ Integrated band-pass filter with 140 kHz center frequency
♦ Maximum gain obtained for pulse light of 1.4 µs and upwards
♦ High LF and DC (ambient) light suppression
♦ Transfer characteristics irrespective of ambient light level
♦ Soft signal and noise limiter with excess ambient light
♦ Fast recovery from flashes
♦ Complementary analogue current source outputs,
   transimpedance can be set by external resistor

   bright ambient light
♦ Options: customised COB versions

OZ9936 operates at a constant operating frequency that eliminates any undesired interference between the controller and LCD panel. OZ9936 drives all types of CCFLs and is able to ignite positive impedance CCFLs.

OZ9936 provides a shutdown delay feature for input brownout condition. The control logic provides a regulated ignition voltage and appropriate protection for over voltage or over-current conditions.
