Input Circuit
The control inputs consist of TTL/CMOS-compatible schmitt-triggers with hysteresis.
Buffer amplifiers are driven by this stages.
Output Stages
The output stages consist of a DMOS H-bridge. Integrated circuits protect the outputs
against short-circuit to ground and to the supply voltage. Positive and negative voltage
spikes, which occur when switching inductive loads, are limited by integrated
freewheeling diodes.
A monitoring circuit for each output transistor detects whether the particular transitor is
active and in this case prevents the corresponding source transistor (sink transistor) from
conducting in sink operation (source operation). Therefore no crossover currents can
occur.
