This IC is especially designed to drive inductive loads (relays, electromagnetic valves).
Integrated clamp-diodes limit the output voltage when inductive loads are discharged.
Four open-drain logic outputs indicate the status of the integrated ciruit. The following conditions are
monitored and signalled:
Input Circuits
The control and enable inputs, both active high, consist of schmitt triggers with hysteresis. All inputs are
provided with pull-down current sources. Not connected inputs are interpreted as low and the respective
output stages are switched off.
In standby mode (STBY = LOW ) the current consumption is greatly reduced.
The circuit is active when STBY = HIGH.
If the standby function is not used, it is allowed to connect the standby pin directly to VS.
Status Signals: The status signals are undefined for 2ms after a power up event or a STBY low to high
transition.
Output Stages
The four power outputs consist of DMOS-power transistors with open drains. The output stages are
short circuit protected throughout the operating range. Each output has it's own zenerclamp. This
causes a voltage limitation at the power transistor when inductive loads are switched off.
Parallel to the DMOS transistors there are internal pull down current sources. They are provided to de
tect an open load condition in the off state. They will be disconnected in the standby mode.
Due to EMI measures there is an internal zenerclamp in parallel to the output stage. It gets active above
33V drain source voltage. This leads to an increasing leakage current up to 1 mA @ V
