The company says the VOMDA1271 draws all the current required to drive its internal circuits from the infrared emitter on the low-voltage primary side of the isolation barrier. No external power supply is required to provide VCC, making the optically isolated MOSFET driver more cost-effective. It is easy to use, AEC-Q102 certified and comes in a space-saving SOP-4 package. The components are available in tape & reel packaging.

VOMDA1271 has an integrated fast turn-off, which only requires 0.7 ms (typ.) to switch off and offers and offer a switch-on time of 0.05 ms. The components have a photovoltaic gate array and therefore do not require an additional power supply to ensure the required insulation test voltage of 3.750 V_RMS. The resulting simplified design enables lower costs and reduces space requirements.

The optically insulated drivers operate reliably in a wide temperature range from -40 °C to 125 °C, making them ideal for use in automotive charging technology. The components are also microcontroller-compatible.
