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 PIN and NIN.
For application where a single control pin (NIN) 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 NIN will turn the high ...
