HT0740

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. The internal supply voltage is provided by the logic input when it is in high state. Package Type 8-lead SOIC (Top view) VIN 1 NC 2 -VOUT 3 +VOUT 4 8 NC 7 GND 6 NC 5 NC See Table 2-1 for pin info...
