TDA8442

GENERAL DESCRIPTION

The TDA8442 provides control of four analogue functions

and has one high-current and two switching outputs.

Control of the IC is performed via the two-line, bidirectional

Features

• Four analogue control outputs

• One high-current output port (npn open emitter)

• Two switching output ports (npn collector with internal

pull-up resistor)

• Power-down reset.
