5.2.1.1. Sensor Power Fault Responses
SENSOR_SUPPLY is designed to survive short-to-battery, short-to-ground, and over-
current events. If these events occur, the circuit will recover as described in the
following table:
Sensor Power Fault Recovery
Event Recovery
Short-to-battery
(sensor voltage = battery voltage) Sensor voltage recovers when the short is removed.
Short-to-ground
(sensor voltage = ground) Sensor voltage recovers when the short is removed.
Over-current
(sensor voltage = ground) Sensor voltage recovers when the over-current
condition is removed.
