Working Principle

The LTC1421CG#TRPBF is designed to provide hot swap protection to power supplies that are subject to high inrush currents. It provides adjustable power limiting and on/off control through an external control signal, along with over-voltage and over-temperature protection. The device’s integrated Push-Pull driver allows it to switch between high current, low current, and no current modes, while the voltage and current control signal mixers ensure the device operates within the required limits.

The LTC1421CG#TRPBF is designed to regulate both voltage and current across the power supply. It features an internal reference voltage that can be adjusted to configure the desired voltage and current settings. The device’s onboard current regulation monitors the current into the power supply and adjusts the output voltage to keep the current within the desired limits. An adjustable over-temperature detection circuit is included to shut off the power supply in the event of an over-temperature condition.

The LTC1421CG#TRPBF also features an adjustable over-voltage detection circuit to automatically shut off the power supply in the event of an over-voltage condition. The device also includes a watch dog timer circuit that can be configured to shut off the power supply if the control signal is not received within the programmed time limit. The device can also be used in high-reliability applications, as it is designed to operate continuously even during surge conditions.
