LED Driver IC
PT6959
DESCRIPTION
PT6959 is an LED Controller driven on a 1/4 to 1/7 duty factor. Fourteen to eleven segment output lines,
4 to 7 grid output lines, one display memory, control circuit are all incorporated into a single chip to
build a highly reliable peripheral device for a single chip microcomputer. Serial data is fed to PT6959
via a three-line serial interface. Housed in a 28-pin SOP, PT6959’s pin assignments and application
circuit are optimized for easy PCB Layout and cost saving advantages.
