Notes:
4. Pulse-testing techniques maintain junction temperature close to ambient temperature; thermal effects must be taken into account separately.
5. The discharge function is active when the device is disabled (when enable is de-asserted). The discharge function offers a resistive discharge
path for the external storage capacitor. This is suitable only to discharge filter capacitors for limited time and cannot dissipate steady state
currents greater than 8mA.
6. Test condition for SOP-8L: Device mounted on FR-4, 2oz copper, with minimum recommended pad layout.
7. Test condition for MSOP-8L-EP: Device mounted on 2” x 2” FR-4 substrate PC board, 2oz copper, with minimum recommended pad on top
layer and thermal vias to bottom layer ground plane.
