HV450

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 NIN 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_DD. The high voltage outputs have pulse by pulse over current protection.
