Description
The radiation hardened IS-2100ARH, IS-2100AEH are high-frequency, 130V half-bridge N-Channel MOSFET driver ICs, which are functionally similar to industry-standard 2110 types. The low-side and high-side gate drivers are independently controlled. This gives the user maximum flexibility in dead time selection and driver protocol. In addition, the devices have on-chip error detection and correction circuitry, which monitors the state of the high-side latch and compares it to the HIN signal. If they disagree, a set or reset pulse is generated to correct the high-side latch. This feature protects the high-side latch from single event upsets (SEUs).

IS-2100ARH and IS-2100AEH NC Pins
These pins have no internal connection to the die inside the package so they are floating. We recommend grounding these pins so as to not leave them floating.

Are there protection diodes internal to the IS-2100ARH / IS-2100AEH between the logic pins and the supply voltage?
... 2. If so, is the part protected as long as the current through the protection diode is limited to a safe value? If so, what is a reasonable safe current? Answers: 1: Yes. 2: Yes, the part will be protected as long as the protection diode current is kept to ...
