[1] No production test, guaranteed by design and qualification
[2] The recessive voltage at pin BUS should be less than 80% of the voltage at V_BAT. The voltage at V_SUP results with consideration
of reverse diode V_SUP = V_BAT - 0,7V
[3] See chapter 2.6 Test Circuit for Dynamic and Static Characteristics
[4] The nominal V_CC voltage is measured at V_SUP =12V. If the V_CC voltage is 100mV below its nominal value then the voltage drop is
V_D = V_SUP – V_CC.
[5] See chapter 4 for application hints.
