HT0740 High-Voltage Isolated MOSFET Driver Features • ±400V Input to Output Isolation • Low Input Logic Current, 500 µA (Maximum) • No External Voltage Supply Required • Floating Isolated Output Drivers • 5V Logic Compatible Applications • Telecommunications • Modems • Solid State Relays • High-side Switches • High-end Audio Switches • Avionics • Automatic Test Equipment General Description The HT0740 is a single-channel high-voltage low input current isolated driver that uses the HVCMOS® technology. It is designed to drive discrete MOSFETs configured as high-side switches up to 400V. The HT0740 generates an independent DC-isolated voltage across +VOUT and –VOUT when the logic input is at a logic high. The HT0740 does not require any external power supplies.
