2 DESCRIPTION
L8202 is a multifunction analog ASIC designed for
MFP Inkjet printer applications.
L8202 integrates 4 full H Bridge drivers, 2 switching
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 either
3.3V or +5V and VDD, programmable by a resistor
divider network from +3V to +17V
It is possible to increase the Output Current capability
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 voltage
is filtered on pin V5 (Typical filter capacitor =
100nF) .
