Electronic Circuit Breaker

FEATURES

DESCRIPTION

The LTC^®4213 is an electronic circuit breaker. An overcur-

rent 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.

Fast 1µs Response Circuit Breaker

3 Selectable Circuit Breaker Thresholds

No Sense Resistor Required

Dual Level Overcurrent Fault Protection

Controls Load Voltages from 0V to 6V

High-Side Drive for External N-Channel MOSFET

Undervoltage Lockout

READY Pin Signals When Circuit Breaker Armed

Two integrated comparators provide dual level overcurrent

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

Small Plastic (3mm × 2mm) DFN and TSOT-23
