The present invention discloses a high voltage switching module having
reduced stress at its driver output stage which in turn controls the gate
of a transistor requiring a high current drive. The switching module
includes a negative elevating circuit, a delay module, a pull-up circuit,
and a pull down circuit. The negative elevating circuit senses a
transition of a logic input signal to generate a control signal. The
first pull-up circuit is operatively coupled to this control signal for
switching the driver output from a negative voltage to a ground voltage.
There is an additional delay module which is configured to provide a
delay in the logic input signal. This delayed logic input signal is
operatively coupled to the second pull-up stage which takes the output of
the driver from GND to VDD. The pull-down circuit is operatively coupled
to the negative elevator for controlling a voltage at the driver output
to the negative level. The module further comprises a switching circuit
that is operatively coupled to the driver output for controlling the
passing of a high voltage with high current requirements.
