Application Notes of Fairchild Semiconductors Semiconductors that are used in Power supplies for products like cell phone chargers, set-top boxes to industrial controls. Fairchild Components are used in Mobile and Handheld Devices for power, backlighting and signal conditioning solutions for a longer battery life. The lighting is moving from power hungry incandescent bulbs to fluorescent, LED or HID lamps. Fairchild Semiconductors have designs for Lighting applications too.

ICM7217 Device Information The ICM7217 is a four digit, presettable up/down counter with an onboard presettable register continuously compared to the counter. The ICM7217 is intended for use in hard-wired applications where thumbwheel switches are used for loading data, and simple SPDT switches are used for chip control. This circuit provides multiplexed 7 segment LED display outputs, with common anode or common cathode configurations available. Digit and segment drivers are provided to directly drive displays of up to 0.8 inch character height (common anode) at a 25% duty cycle. The frequency of the onboard multiplex oscillator may be controlled with [Read More ....]
