APPLICATIO S

TYPICAL APPLICATIO

DESCRIPTIO

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 VCC = 2.3V to 6V.
