AnalogicTech offers a range of products for portable navigation devices (PNDs) and other handheld equipment to fully optimize available energy, minimize losses, and prolong battery life.  For Li-Ion batteries, linear charging solutions are available with the option of an external or internal charging device. Ultra-small packed TrenchDMOS power MOSFETs can be used as load switches to reduce overall power consumption. A more integrated approach is available with single or multiple switches offering integrated level shift, slew-rate control, and protection from over-current and over-temperature conditions.  For the microprocessor core and multi-media processor chipsets, miniature, high-efficiency DC/DC converters and high-speed LDOs are available with supervisory circuits to monitor the supplies.  For color display and keypad backlighting, AnalogicTech’s family of charge pump products drive and control current and brightness in white LEDs.   Finally, application-specific charge pump products are available for driving color RGB diodes, for TFT display biasing, and to provide a USB OTG interface.
