Notes
a. When Mounted on 1” x 1” PCB FR4 Board.
b. Not tested, specified by design.
c. V_LOADDUMP is setup without the DUT connected to the generator per ISO 7637-1 and DIN 40839. Supply voltages higher than V_bb(AZ) require an external
current limit for the GND pin, e.g. witha 150-W resistor in GND connection. A resistor for the protection of the input is integrated.
d. According to ANSI EOS/ESD-S5.1-1983 ESD STM5.1-1998.
