LTC4215IGN#PBF - Hot Swap Controller from Linear Technology

The LTC4215IGN#PBF is a sophisticated hot swap controller designed by Linear Technology to enable safe board insertion and removal from a live backplane. This integrated circuit helps in controlling the inrush current when a card is inserted into a live power distribution bus, preventing glitches on the supply rail, component damage, and system interruption.

This hot swap controller operates over a wide voltage range and is suitable for use in systems with supply voltages from 2.9V to 26.5V. It provides a compact and efficient solution for managing the power applied to boards in high-availability systems such as servers, data centers, and telecommunications equipment.

The LTC4215IGN#PBF features an adjustable current limit, which can be set according to the requirements of the specific application. This ensures that the power device is protected from overcurrent conditions. Additionally, the product includes a circuit breaker function that latches off the external N-channel MOSFET pass transistor when an overcurrent condition persists, providing further protection for the system.

With its multi-function timer, the LTC4215IGN#PBF controls the duration of overcurrent conditions before the circuit breaker function activates. It also has an automatic retry feature, which can be enabled to attempt to re-apply power after a fault condition has been removed, enhancing system reliability.

The device is housed in a narrow 16-lead SSOP package, making it suitable for space-constrained applications. Its part number LTC4215IGN#PBF indicates that it is offered in a lead-free, RoHS-compliant package, which is an important consideration for environmentally conscious designs and for compliance with global regulations.

Overall, the LTC4215IGN#PBF from Linear Technology is a robust and feature-rich hot swap controller that offers precise control over inrush current, protects against overcurrent conditions, and helps to maintain system integrity during card insertion and removal events. Its versatility and protection features make it an ideal choice for managing power distribution in complex electronic systems.
