Product Description

High-Voltage Isolated MOSFET Driver

The HT0740 is a single-channel, high-voltage, low input current isolated driver utilizing HVCMOS technology. It is designed to drive discrete MOSFETs configured as high-side switches up to 400V. The device generates an independent DC-isolated voltage across +VOUT and VOUT when the logic input is high, and does not require external power supplies, deriving its internal supply from the logic input. Key features include 400V input-to-output isolation, low input logic current (500 A max), and no external voltage supply requirement, with floating isolated output drivers and 5V logic compatibility. Applications include telecommunications, modems, solid-state relays, high-side switches, high-end audio switches, avionics, and automatic test equipment.
