The LT1641CS8 is a Positive High Voltage Hot Swap Controller manufactured by LT. This component is engineered to manage the controlled turn-on of a board's supply voltage, enabling safe insertion or removal from a live backplane. This prevents damage to connector pins and system glitches caused by high peak currents during the charging of bypass capacitors.
The device provides essential protection features, including undervoltage and overcurrent protection. A power good output signal is also included to indicate when the output supply voltage is ready. The LT1641CS8 is housed in an SO (Small Outline) package and operates within a temperature range of 0°C to 70°C.
Key functionalities include a programmable foldback current limit with an electronic circuit breaker for protection against short-circuits or excessive supply currents. The controller utilizes an external N-channel pass transistor for power supply control, with current detection and GATE slew rate control provided by external components. Resistors R1 and R2 are used for undervoltage sensing, while R3 and R4 sense the output voltage to signal power good status.
The operating temperature range for the LT1641CS8 is 0°C to 70°C.
The LT1641CS8 is available in an SO package.
The LT1641CS8 has 8 pins.
The RoHS status is RoHS3 Compliant.
The Moisture Sensitivity Level (MSL) is 1 Unlimited.
