In summary, the VOMDA1271T is ideal as a MOSFET driver in a pre-charge application in an electric vehicle. It provides the voltage to drive the gate of a MOSFET while providing galvanic isolation of low-voltage circuitry and controller. It uses light as the connector versus a mechanical relay which uses contactors which are less reliable and wear over time. It can be directly connected to a microcontroller as it needs only 5mA forward current to produce an output voltage of 8.2V. The VOMDA1271T features a turn-off circuit to achieve fast turn-off of the MOSFET. It is qualified to the AEC-Q102 standard, giving automotive design engineers confidence to use it.
