ST7586S
Liquid Crystal Driver Power Circuit
The built-in power circuits generate the voltage levels which are necessary to drive the liquid crystal. It consumes low power
with the fewest external component. The built-in power system has voltage booster, voltage regulator and voltage follower
circuits. Before power ST7586S is OFF, a Power OFF procedure is needed. Please refer to the OPERATION FLOW section.
External Component of Power Circuit
The recommended external power components need only three capacitors. The detailed values of these three capacitors are
determined by panel size and loading.
