FEATURES
The LTC
®
4213 is an Electronic Circuit Breaker. An over-
current circuit breaker senses the voltage across the drain
and source terminals of an external N-channel MOSFET
with no need for a sense resistor. The advantages are a
lower cost and reduced voltage and power loss in the
switch path. An internal high-side driver controls the
external MOSFET gate.
Two integrated comparators provide dual level over-
current protection over the bias supply to ground common
mode range. The slow comparator has 16µs response
while the fast comparator trips in 1µs. The circuit breaker
has three selectable trip thresholds: 25mV, 50mV and
100mV. An ON pin controls the ON/OFF and resets circuit
breaker faults. READY signals the MOSFET is conducting
and the circuit breaker is armed. The LTC4213 operates
from V
CC
= 2.3V to 6V.
