3. The discharge function is active when the device is disabled (when enable is de-asserted). The discharge function offers a resistive discharge path
4. Device mounted on FR-4 substrate PCB, 2oz copper, with minimum recommended pad layout.
5. Device mounted on 2” x 2” FR-4 substrate PCB, 2oz copper, with minimum recommended pad on top layer and thermal vias to bottom layer ground
