(1) Electrostatic discharge (ESD) to measure device sensitivity or immunity to damage caused by assembly-line electrostatic discharges into the device.
(2) The passing level per AEC-Q100 Classification H2.
(3) The passing level per AEC-Q100 Classification C5.
(4) Surges per EN61000-4-2, 1999 applied between USB connection for V(BUS) and ground of the TPS2556EVM (HPA423, replacing TPS2556 with TPS2556-Q1) evaluation module (SLUU393). These were the test levels, not the failure threshold.
