The LT1641-2IS8#TRPBF is an 8-pin hot swap controller that enables safe insertion and removal of boards from live backplanes. It utilizes an external N-channel pass transistor to control the board supply voltage, allowing it to ramp up at a programmable rate. The device supports supply voltages ranging from 9V to 80V and features a high-side switch driver.
Key functionalities include a programmable analog foldback current limit circuit. If the current limit is exceeded for a programmable duration, the LT1641-2 automatically retries after a time-out delay. The controller also provides a PWRGD output to indicate when the output voltage is within tolerance and an ON pin for programmable undervoltage lockout. Overvoltage protection is also a feature.
This hot swap controller is available in an 8-lead SOIC package, suitable for surface mounting. Its applications include industrial high-side switching and circuit breakers, as well as 24V/48V industrial and alarm systems. The device offers programmable features such as slew rate control, fault timeout, and undervoltage lockout.
