LTC4362IDCB-1

Power Management - Specialized Overview

The LTC4362IDCB-1 is a monolithic overvoltage/overcurrent protector designed to safeguard 2.5V to 5.5V systems from power supply overvoltage. It controls an internal 40mΩ N-channel MOSFET in series with the input power supply. During overvoltage transients, the device turns off the MOSFET within 1μs, isolating downstream components. The part features delayed start-up at plug-in and rides through inductive cable transients without requiring external transient voltage suppressors.

Power Management - Specialized Feature Summary

• Monolithic integration of overvoltage and overcurrent protection functions
• Internal 40mΩ N-channel MOSFET for low insertion loss
• Fast transient response isolating downstream components within 1μs
• Delayed start-up capability during plug-in events

Power Management - Specialized Applications

• Portable devices with multiple power supply options
• Systems powered by wall adaptors
• Car battery adaptor applications
• USB port powered circuits

Power Management - Specialized Procurement Notes

Verify the specific suffix DCB-1 against official Analog Devices documentation to confirm pinout and threshold settings. Ensure the application environment matches the specified 2.5V to 5.5V system range. Confirm package compatibility and thermal requirements for the DFN-6 package before procurement.

Power Management - Specialized Selection Notes

Select this component for applications requiring robust protection against power supply overvoltage and overcurrent conditions. It is suitable for portable electronics where space is limited due to its monolithic design. Consider the internal MOSFET resistance and transient response speed when evaluating system performance under fault conditions.
