Note 1: All voltages are with respect to the VNEG pin voltage.
2: The leakage currents on the ENABLE and RESTART pins are strongly dependent on the applied voltage level. The spec-
ified levels represent normal operating conditions. Higher leakage current may be measured at different input voltages.
3: Negative current is defined as coming out of the pin.
