Description

LTC1422CS8 - Hot Swap Controller from Linear Technology

The LTC1422CS8 is a sophisticated hot swap controller designed by Linear Technology to enable safe insertion and removal of printed circuit boards from a live backplane. This component is housed in an 8-lead SO package and is engineered to manage electronic circuitry's inrush current to prevent glitches on the power supply rail, which could otherwise disrupt the operation of existing boards.

The LTC1422CS8 operates by controlling an external N-channel MOSFET to gently power up capacitors, thereby limiting the inrush current to a safe level. It boasts an adjustable supply voltage range from 4.5V to 16.5V, making it versatile for various applications. The current limit is also adjustable, which allows the user to set the maximum inrush current according to the specific requirements of their system.

One of the key features of the LTC1422CS8 is its ability to provide a controlled power-down sequence. This is particularly useful in situations where the system needs to be safely powered off without damaging the components. Additionally, the device includes overcurrent protection, which safeguards the circuit from excessive currents that could potentially cause harm.

Other notable features of the LTC1422CS8 include its undervoltage lockout, which ensures that the hot swap controller remains off when the supply voltage is too low, and its charge pump circuitry, which drives the gate of the external N-channel MOSFET above the supply voltage to ensure it is fully enhanced and provides the lowest possible on-resistance.

For diagnostic and control purposes, the LTC1422CS8 offers a status flag output that indicates the presence of an overcurrent condition or if the MOSFET is in the off state. This allows for easy integration with system monitoring circuits and microcontrollers. Its robust design and comprehensive feature set make the LTC1422CS8 an ideal choice for high-reliability systems that require hot swapping capabilities, such as servers, RAID systems, and telecommunications equipment.
