DESCRIPTION

L8202 is a multifunction analog ASIC designed for

MFP Inkjet printer applications.

L8202 integrates 4 full H Bridge drivers, 2 switch-

ing Buck type voltage regulators, 4 operational

amplifiers, 6 open drain drivers, Reset Generation

circuitry and over temperature protection circuitry.

The regulated Voltages are: VCC that can be ei-

ther 3.3V or +5V and VDD, programmable by a re-

sistor divider network from +3V to +17V

It is possible to increase the Output Current capa-

bility of the VDD regulator by adding an external

discrete Power DMOS.

An internal regulator is present in the IC in order to

supply several internal blocks. The 5V output volt-

age is filtered on pin V5 (Typical filter capacitor =

100nF) .
