Mingjiada Supply ADI LTC4260 Series Positive High Voltage Hot Swap Controller

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of the [ADI] LTC4260 series positive high-voltage hot-swap controllers. Designed for hot-swap management of circuit boards on positive high-voltage power rails, these devices integrate I²C-compatible monitoring functions. Whilst providing surge current limiting and fault protection, they also enable the monitoring of operational parameters such as voltage and current, making them suitable for applications requiring advanced power management, including telecommunications, servers, industrial control and distributed power architectures.

The 【ADI】LTC4260 Hot Swap™ controller enables the safe insertion and removal of circuit boards from a live backplane. By utilising an external N-channel power transistor, it allows the board’s supply voltage to ramp up at an adjustable rate. An I²C interface and an on-board ADC enable monitoring of the board’s current, voltage and fault status.

The LTC4260 features an analogue current-limit recovery function; if the LTC4260 remains in a current-limit state beyond an adjustable timeout delay, it can be configured to perform a lockout or retry operation following this event.

Furthermore, the LTC4260 offers additional features, including interrupting the host in the event of a fault, notifying the host when the output power is in good condition, detecting the insertion of a load board, and performing power-up operations in both the on and off states.
