The LTC4217CFE#PBF is an advanced Hot Swap Controller from Linear Technology. It provides the necessary control and protection the circuit designer needs to safely and reliably turn on, monitor and turn off power sequenced board level loads. The controller is designed to work independently, without the need for an external system or microcontroller. It offers comprehensive power sequencing and monitoring functions. It maintains system integrity in the event of an over/under voltage, over or over-temperature conditions. In addition, it provides a programmable maximum power and soft start timing.

The LTC4217CFE#PBF Hot Swap Controller is easy to configure. All the necessary functions are accessible by pin, including output signal and data bits. Output signal port is used to communicate within the system and with peripheral devices. Output signal and data bits allow the controller to be used as part of a AC coupled signal circuit, or as part of an AC coupled signal chain controller.

The LTC4217CFE#PBF Hot Swap Controller provides direct control over board level loads. It offers a wide range of features, such as over-temperature shutdown, auto start-up, programmable soft start, variable delay times, enable and disable control, variable power limit control, variable current limit control and programmable supply voltage level. It also provides a range of independent low-power shut down inputs.

The output of the controller is divided into two separate voltage ranges: the low voltage output range, providing two independent output paths (HV1, HV2) of up to 21V, and the high voltage output range, providing two separate output paths (HV3, HV4) of up to 45V. An internal logic circuit provides a monitor output to detect when either the low or high voltage is exceeded. This output can be used to power an external supply or to send an out of range alert.

The LTC4217CFE#PBF Hot Swap Controller also offers a wide range of features. It is designed to be easy to set up and configure with use of a pre-set control logic. It offers a high degree of programmability with user selectable logic levels and optional control signal inputs. It provides reverse current protection and increased thermal protection by controlling the maximum output current. Additionally, it features an external short circuit detection and programmable power sequencing.

The LTC4217CFE#PBF Hot Swap Controller provides a reliable and efficient way of controlling and protecting power sequenced board level loads. With a wide range of features and capabilities, the LTC4217CFE#PBF is a robust solution for Hot Swap applications.
