VNH7040AY

Immunity against transient electrical disturbances

The immunity of the device against transient electrical emissions, conducted along the

supply lines and injected into the VCC pin, is tested in accordance with ISO7637-2:2011 (E)

and ISO 16750-2:2010.

The related function performance status classification is shown in Table 15: ISO 7637-2

electrical transient conduction along supply line.

Test pulses are applied directly to DUT (Device Under Test) both in ON and OFF-state and

in accordance to ISO 7637-2:2011(E), Section 4. The DUT is intended as the present device

only, without components and accessed through VCC and GND terminals.

Status II is defined in ISO 7637-1 Function Performance Status Classification (FPSC) as

follows: “The function does not perform as designed during the test but returns automatically

to normal operation after the test”.
