Application Description
This IC is specially designed to drive inductive loads (relays, electromagnetic valves). An integrated
clamp-diode limits the output voltage when inductive loads are discharged.
For the detection of errors there is a open-drain status output, which monitors the following errors by
logic level:
- overloading of output (also shorted load to supply) in active mode
- open and shorted load to ground in active and inactive mode
- thermal overload.
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 output consists of a DMOS-power transistor with open drain. The output stage is shorted
load protected troughout the operating range. The integrated clamp-diode limit voltage spikes produ-
ced when inductive loads are discharged.

Protective Circuits
An integrated diode protects the device against reverse polarity of the operating voltage.
The load circuit withstands reverse poling within the limits of the maximum ratings (no shorted load
permissible at the same time).
The outputs are protected against current overload and thermal overload.
Error Detection
The status output signals the switching state at normal operating conditions (LOW = off; HIGH = on)
and in case of errors. The outputs are set according to the diagnostic table below.
If current overload occurs, the error condition is stored into an internal register and the output is shut-
down. To reset the register, the control input of the corresponding channel has to be switched off and
then on again.
Open load is detected in on- and off-modus: In on-modus the load current is monitored , in the off-
modus the ouput voltage is monitored.
The open load voltage threshold is programmable via the voltage supplied to the VC.
The state of the error detection circuit is directly dependent on the input status.
