the external N-channel starts to conduct during the second
timing cycle (Time Points 12 to 16).
Sense Resistor Considerations
The fault current level at which the LTC4212s internal
electronic circuit breaker trips is determined by a sense
resistor connected between the LTC4212s V
CC
and SENSE
pins and two separate trip points. The first trip point is set
