Table 2: Electrical Specification
(1) The programming voltage defines the threshold at which the ASIC goes into PTC mode, where the
output pin becomes bidirectional. Write access is eventually defined by the locking bits as described
in Section 6.1
(2) The overvoltage threshold will disconnect all internal supplies (Vana, Vdig & Vprot) from V_DD; the
output becomes high impedant.
(3) The saturation voltage is the rail voltage the output amplifier can reach actively with R_PD connected.
(4) The maximum current the output stage can deliver to keep its DC value, in case the output is pulled
to one of the rails by means of an external power supply, while V_DD = 5V.
(5) The leakage current is in fact the current sourced by the output in case of an OBD detection (broken
ground), where the output goes into high-Z mode. For better contacting at the connectors over
lifetime and bigger rail-to-rail operation, the smaller pull-down resistors from this specification are
recommended at ECU side.
