Application Description
This IC is specially designed to drive inductive loads (relays, electromagnetic valves). Integrated
clamp-diodes limit the output voltage peak when switching off an inductive load.
For the detection of errors there are two status outputs, which monitor the following errors by logic
levels:
− thermal overload,
− open and short load to ground in active an inactive mode,
− overloading of output (also shorted load to supply) in active mode.
Circuit Description
Input Circuits
The control and enable inputs, all active high, consist of Schmitt triggers with hysteresis. All inputs are
connected with pull-down current sources. Not connected inputs are interpreted as "low“.
Switching Stages
The power outputs consist of a DMOS power transistor with open drain. The output stages are short-
load-protected throughout the operating range. Integrated clamp-diodes limit voltage spikes produced
when inductive loads are discharged.
Protective Circuit
The outputs are protected against current overload. There is no protection against reverse polarity of
the supply voltage.
