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 voltage P-Channel on and the N-Channel off. The outputs can drive up to 5 RENs.
