Circuit Description
Logic Supply
The logic is supplied with 4.5 up to 60 Volt by the V
the logic is shut down and the output stages are switched off.
Direct Inputs
ENA
The ENA/FREEZE input can be used to enable and/or to freeze the output control of the
IC or to cut off the complete IC.
By pulling the ENA input to low, i.e. applying a Voltage V
The power stages are switched off and the current consumption is reduced to I
By applying a Voltage V
in their former state. All input signals will be ignored.
By pulling the input to high, the IC is in Enable mode. All input signals are output.
The ENA - pin has an internal pull-down.
IN1 / IN2
Each output is independently controlled via the respective input pin. The input pins are
high active. If the common enable pin is high, the individual input signals are output. The
input pins have an internal pull-down.
