Key Features
- Automatic retry after overvoltage or overcurrent fault, restoring power without manual intervention in unattended systems
- Single-channel monitoring with fast fault response — disconnects load within microseconds to protect sensitive downstream circuits
- Compact 8-pin DFN (2mm x 3mm) package enables high-density power protection in space-constrained board designs
- Fixed threshold operation requires minimal external components, reducing design complexity and BOM cost
Applications
The LTC4362IDCB-2#TRMPBF is used in power distribution circuits for industrial control equipment, telecom line cards, and server power rails where transient overvoltage or overcurrent events could damage downstream ICs. Its automatic retry feature makes it ideal for hot-swap and field-deployed systems that must recover from fault conditions without operator intervention. Battery-powered portable devices also benefit from its overcurrent protection to prevent damage during short-circuit events or incorrect load connections.

Frequently Asked Questions
How quickly does the LTC4362IDCB-2#TRMPBF respond to an overvoltage or overcurrent fault event?
The LTC4362IDCB-2#TRMPBF responds to fault conditions within microseconds by turning off the external N-channel MOSFET pass element and disconnecting the load from the supply. This fast response time — typically on the order of 1 µs to 10 µs depending on gate capacitance — is critical for protecting sensitive downstream ICs such as FPGAs, microcontrollers, and memory devices from damaging voltage or current transients.
What distinguishes the LTC4362IDCB-2 from the LTC4362IDCB-1 variant in terms of fault handling behavior?
The LTC4362IDCB-2 variant uses an automatic retry mode: after a fault is detected and the load is disconnected, the device waits for a fixed timeout period (typically around 50 ms) and then reattempts to re-enable the load. The -1 variant requires an external reset or power cycle to recover. The auto-retry behavior of the -2 makes it more suitable for unattended remote equipment and industrial applications where manual resets are impractical.
What external components are needed to implement a complete protection circuit with the LTC4362IDCB-2#TRMPBF?
A complete protection circuit requires only an external N-channel power MOSFET (sized for the expected load current, e.g., rated for 5 A or more), a current-sense resistor (typically 10 mΩ to 50 mΩ), and bypass capacitors on the supply and gate nodes. The LTC4362IDCB-2#TRMPBF uses fixed internal thresholds, so no external resistor dividers or programmable components are needed, reducing total BOM to just 4 to 6 passive components around the IC.
In which industrial or telecom applications is the LTC4362IDCB-2#TRMPBF most commonly deployed?
The LTC4362IDCB-2#TRMPBF is commonly deployed on 12 V or 24 V power distribution rails in industrial programmable logic controllers (PLCs), telecom equipment line cards, and network switches where inadvertent short circuits or voltage transients could cause widespread board damage. Its 8-pin DFN package and auto-retry feature are also valued in rackmount server power buses and distributed power architectures requiring compact, self-healing protection on each load branch.
