The LTC4211CMS#PBF is a Hot Swap Controller manufactured by LT, designed to manage power supply voltages during the insertion and removal of printed circuit boards from live backplanes. This controlled manner prevents transient currents from damaging connector pins or causing system glitches.
The device incorporates a 1.236V bandgap reference and precision voltage comparators for monitoring output supply voltage. It provides a system reset signal when the board supply voltage drops below a predetermined level. The under-voltage lockout (UVLO) mode activates if the supply voltage falls below 2.18V, pulling the GATE pin low. The chip restarts when the supply voltage rises above 2.3V.
Key features include adjustable under-voltage lockout levels and a dual-function fault monitor. The LTC4211CMS#PBF is suitable for applications requiring safe board insertion into live systems, preventing system resets and protecting hardware.
This component is available in a CMS package, facilitating integration into various electronic designs.
The reference voltage is 1.236V.
The under-voltage lockout threshold is 2.18V.
The chip restarts after the supply voltage rises above 2.3V.
The reset threshold is 1.236V when the voltage drops below, and 1.239V when the voltage rises above.
The system enters the plug-in cycle after the ON pin rises above 1.316V.
