6. Pulse-testing techniques maintain junction temperature close to ambient temperature; thermal effects must be taken into account separately.
7. The discharge function is active when the device is disabled (when enable is de-asserted or during power-up power-down when V
The discharge function offers a resistive discharge path for the external storage capacitor for limited time.
