Product details
Overview
HV430WG-G from Supertex Inc. is a high-voltage PWM ring generator IC designed to drive external N-channel and P-channel MOSFETs in push-pull configuration for telecom line interface applications. It delivers 105Vrms ring signal output, features logic-level 5.0V CMOS control, adjustable deadband (35–175ns), overcurrent protection with external sense resistors, and power-on reset functionality.
For engineers reviewing the HV430WG-G datasheet, HV430WG-G pinout, HV430WG-G application, or HV430WG-G equivalent, key selection considerations include its dual/single-control mode operation, ±220V high-voltage supply capability, fault detection via open-drain FAULT output, and 20-lead SOW package compatibility with telecom line access card designs.
Technical Context
The HV430WG-G implements independent gate drive control for external high-voltage MOSFETs via VPGATE and VNGATE outputs, with internal linear regulators generating VPP2 (+200V typ) and VNN2 (−200V typ) from VPP1/VNN1 supplies. Pulse-by-pulse overcurrent sensing on VPSEN and VNSEN enables cycle-by-cycle current limiting with 150ns fault hold time.
In dual-control mode (MODE = high), PIN and NIN directly control P-channel and N-channel MOSFETs with lockout circuitry preventing simultaneous conduction; in single-control mode (MODE = low), NIN drives both outputs complementarily with user-adjustable deadband set by DEADBAND pin resistor (5.6kΩ–18kΩ).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage ring generator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX14951 | Integrated HV MOSFETs; no external FET required; lower max VPP1 (120V) | Suitable for lower-voltage ring applications; eliminates external FET layout complexity | Select MAX14951 when board space and BOM count reduction outweigh need for 105Vrms output |
| UCC3911 | Single-output topology; no complementary P/N drive; fixed 120ns deadband | Designed for simpler single-FET ringing circuits; lacks dual-sense overcurrent protection | Select UCC3911 for cost-sensitive designs where full push-pull control and independent overcurrent sensing are not required |
Compared with HV430WG-G, MAX14951 integrates power switches but sacrifices 105Vrms capability, while UCC3911 offers lower system cost at the expense of flexible control architecture and dual-sense fault detection - making HV430WG-G optimal for telecom-grade line cards demanding full rail-to-rail drive and robust protection.

FAQ
What is the maximum allowable high-voltage supply for HV430WG-G?
The HV430WG-G supports VPP1 up to +220V and VNN1 down to −220V, with absolute maximum ratings of +340V differential (VPP1 − VNN1). Operation within the recommended range of +50V to +200V for VPP1 and VPP1 − 325V to −50V for VNN1 ensures reliable performance in telecom ring signal generation. Exceeding these limits risks permanent damage.
How does the HV430WG-G implement overcurrent protection?
The HV430WG-G uses pulse-by-pulse overcurrent sensing on VPSEN and VNSEN pins, each monitoring the source voltage drop across external sense resistors connected to the P-channel and N-channel MOSFETs. When either sense voltage exceeds its threshold (VPP1 − 1.15V or VNN1 + 1.15V), the FAULT output asserts low and remains active for four consecutive cycles unless cleared by ENABLE or RESET.
Can HV430WG-G operate in both single- and dual-control modes simultaneously?
No, the HV430WG-G operates exclusively in one mode at a time, selected by the MODE pin voltage. A logic high on MODE enables dual-control mode where PIN and NIN independently control POUT and NOUT; a logic low configures single-control mode where NIN drives both outputs complementarily with adjustable deadband. The MODE pin must be hard-wired to VDD or SGND - dynamic switching between modes is not supported.
What is the purpose of the DEADBAND pin on HV430WG-G?
The DEADBAND pin on HV430WG-G accepts an external resistor to ground that sets the break-before-make interval between P-channel and N-channel MOSFET switching transitions in single-control mode. With RDB = 5.6kΩ, deadband is 35–70ns; with RDB = 18kΩ, it extends to 105–175ns. This prevents cross-conduction and shoot-through current during switching, critical for reliability in high-voltage push-pull topologies.
Is HV430WG-G RoHS-compliant and lead-free?
Yes, the "-G" suffix in HV430WG-G explicitly denotes a lead (Pb)-free and RoHS-compliant package. The device meets EU Directive 2011/65/EU requirements and is manufactured using environmentally compliant materials and processes, with full traceability documentation available upon request for HV430WG-G procurement.
