7 × 17 (119) Dot Matrix LED Driver IC
Overview : Easily configure colorful information displays and illumination devices
The BD26502GUL integrates a 7ch PMOS high side switch, 17ch constant current circuit, 1/7 time division circuit, and pattern generator on a single chip.
Key Feature 1 : 13-pattern generator and 8-way automatic scroll functions reduce microcontroller load
A 13-pattern generator with slope function is built in, significantly reducing microcontroller load. All dots can be randomly selected. Compatible with both single- and full-color LEDs for illumination.
Key Feature 2 : Thin, compact package (4.1 to 4.1 to 0.55mm max.) contributes to greater space savings
Offered in a WL-CSP only 0.55mm thick (max.) - equivalent to the thickness of many of the peripheral components such as capacitors and resistors.
Key Feature 3 : Only one external resistor required
Only one external component (resistor) is required for setting the max. current, unlike conventional solutions that need a referencel voltage filter capacitor and oscillator frequency-setting capacitor. The result is a smaller board size and simpler design.
