General Description
The Supertex HV450 is a PWM high voltage ring generator. The
high voltage output P- and N-channel transistors are controlled
independently by the logic inputs P
IN
and N
IN
. For application
where a single control pin (N
IN
) is desired, the mode pin should
be connected to Gnd. This adds a 200ns deadband on the
control logic to avoid cross conduction on the high voltage
output. A logic high on N
IN
will turn the high voltage P-Channel on
and the N-Channel off. The outputs can drive up to 5 RENs. The
HV450 can drive external MOSFETs for applications requiring
larger loads. The IC can be powered down by connecting the
enable pin to V
. The high voltage outputs have pulse by pulse
over current protection.
