Description : OZ8602 is a highly integrated battery charge controller with adapter current sense and an internal wakeup circuit. It can operate as a stand-alone charger or under the supervision of a host microcontroller.
Part Number : 8602GN, OZ8602GN Function : Battery Charge Controller Package : SOP 16 Pin Manufacturers : O2micro
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.

FEATURES • Negative PWM dimming polarity • Constant operating frequency • Drives positive/negative-impedance lamps during ignition • High drive current for external MOSFETs • User-defined ignition time and shutdown delay time • Multiple mode dimming control • Built-in intelligence for ignition and normal operation of CCFLs • Built-in open-lamp protection and over voltage protection for backlight system • Optimized soft-start function
O2micros OZ998 Multi-DIMM Selector supports the switching between a primary SMBus and 3 other secondary SMBus. This function is particularly useful for DIMM devices and the support of Intel’s PAS (Preboot Authentication Service).
The ta9687 offers a high level of integration, while maintaining flexibility and high-efficiency operation that reduces external component heating, resulting in higher reliability and longer CCFL life. The proprietary design technique provides a simple, low-cost system solution.
allows the implementation of Green PC Desktop Chipsetsin notebook designs at considerably lower cost than conventional methods while closing the technology gap between desktop and notebook computers by offering an extensive number of powerful power management and general purpose I/O features. With the OZ990 stand-alone PMU capability, the ability to provide the One-Shot Design for PMU/BIOSpractically eliminates the need to redesign PMUs to match the ever-changing core logic Chipsets. The OZ990 provides the perfect solution for leading
notebook vendors to stay ahead of the competition.
