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 +V_OUT and –V_OUT 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.
