LTC2909IDDB-2.5#TRPBF

LTC2909IDDB-2.5#TRPBF is a low-power, wide-temperature range monitoring IC that operates over a temperature range of -40°C to 125°C. It is specifically designed to detect and protect a wide range of high-side system components, such as MOSFETs, FETs, power ICs, and ICs in high- voltage applications. This IC can sense the current, temperature, and voltage of power systems and provide protection by detecting faults and signaling the microcontroller or other system control unit.

This IC is part of the Linear Technology family of PMIC Supervisors and operates at low power with a typical operating current of only 0.45uA. It provides over-current, over-temperature, over-voltage, and under-voltage protection. The monitoring conditions are adjustable and the protection limits are individually programmable. Its trip level for each of the monitored signals is programmable with a resistor and a capacitor. There is also an external reset signal input, which allows the device to be reset from an outside source.

The LTC2909IDDB-2.5#TRPBF features a low on-resistor (RON), providing a high current leakage capability of up to 2A. It also has an open-drain output, allowing the device to be connected to an external microcontroller or system control unit. The open-drain output enables the user to simply disconnect the device from the microcontroller or system control unit when not needed.

The device also features a threshold detect pin, which enables it to detect an over-voltage condition. If the voltage on the device\'s float pin is higher than the programmed trip level, the output will be activated, indicating an over-voltage condition. Finally, it also has a temperature sensor and an internal temperature-compensated timing circuit, which allows the device to accurately monitor the temperature of the system.

The LTC2909IDDB-2.5#TRPBF is primarily used in high-voltage applications, primarily in data centers, where it can detect faults and protect components from damage. The device can be used to monitor voltage, current, and temperature to prevent overloading and overheating of components. It can also detect faults, such as those caused by short circuits, and alert the system control unit. The device can also be used to monitor the temperature of components to ensure their reliable operation in various environmental conditions.

The LTC2909IDDB-2.5#TRPBF is a versatile device that, when combined with programming instructions, can provide effective protection for high-voltage circuits and components, ensuring reliable operation and long lifespan. Its low operating current, adjustable monitoring conditions, and open-drain output make it a great fit for many high-voltage applications.
