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 N-channel and P-channel MOSFETs in a push-pull configuration. Overcurrent protection is implemented for both the P-channel and N-channel MOSFETs. External sense resistors set the over-current trip point.

FEATUREs
► 105Vrms ring signal
► Output overcurrent 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
