| HT0740 High Voltage, Isolated MOSFET Driver Features 400V input to output isolation Low input logic current, 500A max No external voltage supply required Floating isolated output drivers 5.0V logic compatible General Description The Supertex HT0740 is a single channel, high voltage, low input current, isolated driver utilizing Supertex's proprietary HVCMOS(R) 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 the pair of outputs when the logic input is at a logic high. The HT0740 does not require any external power supplies. The internal supply voltage is supplied from the logic input when it is in the high state. Applications Telecommunications Modems Solid state relays High side switches High end audio switches Avionics ATE Block Diagram Isolation Barrier VIN 1 Logic & Internal Clock R 4 + VOUT - 3 Driver 10R R GND 7 VISO HT0740 Ordering Information Device HT0740 Package Options 8-Lead SOIC (Narrow Body) HT0740LG HT0740LG-G -G indicates package is RoHS compliant (`Green') Absolute Maximum Ratings Parameter Input to output isolation voltage, VISO Logic input voltage, VIN Operating temperature Storage temperature Soldering temperature 1 Pin Configuration Value 400V -0.5 to +7.0V -40C to +85C -55C to +150C 300C VIN 1 NC 2 8 NC GND HT0740 7 -VOUT 3 +VOUT 4 6 NC 5 NC HT0740 (Top View) Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. Continuous operation of the device at the absolute rating level may affect device reliability. All voltages are referenced to device ground. Note 1. Distance of 1.6mm from case for 10 seconds.
