The LT1640ALIS8#TRPBF is an 8-pin Hot Swap controller designed for safe board insertion and removal from live -48V backplanes. It operates within a voltage range of -10V to -80V.
Key features include programmable inrush current control, a programmable electronic circuit breaker for system protection against shorts, programmable overvoltage protection, and programmable undervoltage lockout. The device also provides a Power Good control output.
This controller is suitable for applications such as central office switching and -48V distributed power systems. It is available in an 8-SOIC package and is designed for surface mount applications.
The LT1640AL/LT1640AH series allows for safe board insertion and removal from live backplanes. Inrush current is limited by controlling the gate voltage of an external N-channel pass transistor. The pass transistor is turned off if the input voltage is outside the programmable undervoltage or overvoltage thresholds. A programmable electronic circuit breaker protects the system against shorts.
