OPERATION
SENSE RESISTOR CONSIDERATIONS
The fault current level at which the LTC4211s internal
electronic circuit breaker trips is determined by a sense
resistor connected between the LTC4211s V
CC
 and SENSE
pins and two separate trip points. The first trip point is
set by the SLOW COMPs threshold, V
CB(SLOW)
 = 50mV,
and occurs should a load current fault condition exist for
more than 20約. The current level at which the electronic
circuit breaker trips is given by Equation 8:

The second trip point is set by the FAST COMPs threshold,
V
CB(FAST)
 = 150mV, and occurs during fast load current
transients that exist for 300ns or longer. The current level
at which the circuit breaker trips in this case is given by
Equation 9:

For proper circuit breaker operation, Kelvin-sense PCB
connections between the sense resistor and the LTC4211s
V
CC
  and SENSE pins are strongly recommended. The
drawing in Figure 11 illustrates the correct way of making
connections between the LTC4211 and the sense resis-
tor. PCB layout should be balanced and symmetrical to
minimize wiring errors. In addition, the PCB layout for the
sense resistor should include good thermal management
techniques for optimal sense resistor power dissipation.
The power rating of the sense resistor should accommodate
steady-state fault current levels so that the component is
not damaged before the circuit breaker trips. Table? in
the Appendix lists sense resistors that can be used with
the LTC4211s circuit breaker.
