The LT1641-1IS8#PBF is an 8-pin Hot Swap controller from Analog Devices that enables safe insertion and removal of boards from live backplanes. It utilizes an external N-channel pass transistor to ramp up the board supply voltage at a programmable rate, controlling supply voltages ranging from 9V to 80V.
Key features include a programmable analog foldback current limit circuit. If the current limit is exceeded for a programmable time, the N-channel pass transistor is latched off, as indicated by the LT1641-1 designation. The device also offers programmable undervoltage lockout via the ON pin and indicates when the output voltage is within tolerance with the PWRGD output.
This controller is suitable for industrial applications such as 24V/48V industrial/alarm systems. It is available in an 8-lead SOIC package, designed for surface mounting.
The operating temperature range for this device is -40°C to 85°C, and it has a supply current of typically 5.5mA at 3V ON voltage. The undervoltage lockout threshold is typically 8.3V.
