The LTC1644CGN#TR PBF is a high-performance, high-voltage, hot-swap controller designed to provide programmable current limit protection and accurate power-on sequencing of PC boards and other circuits. It is widely used in applications such as hot-swap power conversion, hot-swap power sequencing, and fail-safe over-current protection in a variety of industries, including automotive, industrial, medical, and consumer products.

PMIC - Hot Swap Controllers are designed to ensure safe, orderly and efficient startup and shutdown of integrated circuits. They provide a reliable power supply and current limiting protection, and can be programmed to power on and off connected devices in a specific order. The LTC1644CGN#TRPBF operates at up to 32V and provides superb power supply rejection rate (PSRR), making it an ideal solution for providing high-speed current protection in harsh environments, including temperature extremes and vibration.

The LTC1644CGN#TRPBF is equipped with a wide range of features including overtemperature protection, adjustable current limit and adjustable turn-on and turn-off delay. User-programmable over-temperature protection eliminates the need for external discrete comparators, reducing design complexity and cost. The adjustable current limit is set by an external resistor and is adjustable up to 10A, allowing for a wide range of power delivery options without the need to change components.

The LTC1644CGN#TRPBF also features programmable rising and falling delays, which can be used to sequence the startup of multiple devices or ensure that devices are powered off in a certain order. This ensures that the desired sequence is maintained during extreme environmental conditions. The programmable delays can be accurately adjusted in increments as small as 25ns, which makes it ideal for controlling the power up of multiple PC boards or devices.

The LTC1644CGN#TRPBF is low-noise, fast-transient and high-impedance hot-swap controller, making it great for applications where power supplies switch frequently. Its low audible noise control and fast transient response time make it a reliable option for applications that require the highest performance, such as communications equipment, medical equipment and industrial machines.

In summary, the LTC1644CGN#TRPBF is a high performance hot-swap controller ideally suited for applications requiring power-on sequencing, over-current protection and fast transient response. With its adjustable current limit and programmable rising and falling delays, the hot-swap controller provides reliable power sequencing solutions even in harsh environments. With its low audible noise control and PSRR, it is an excellent choice for applications that require the highest performance.
