General Description
The Supertex HV430 is a high voltage PWM ring generator integrated circuit. The high voltage outputs, VPGATE and VNGATE, are used to drive the gates of external high voltage P-channel and N-channel MOSFETs in a push-pull configuration. Over current protection is implemented for both the P-channel and Nchannel MOSFETs. External sense resistors set the over-current trip point.

Features
❏ 105Vrms ring signal
❏ Output over current protection
❏ 5.0V CMOS logic control
❏ Logic enable/disable to save power
❏ Adjustable deadband in single-control mode
❏ Power-on reset
❏ Fault output for problem detection

Applications
❏ Line access cards
❏ Set-top/Street box
