Hot-swap power management ICs are designed to control and protect electronic loads, reducing ownership costs of electronic devices and appliances during production and in the field.
They are ideal for all applications that need to perform hot-plug/hot-swap operations or require a high level of flexibility and reliability. In such applications, a complete and accurate control of the inrush current during startup/hot plug, along with overcurrent/overvoltage protections are crucial and can make the difference in terms of final cost of maintenance and cost of quality.
Compared to traditional protection devices, hot-swap power management ICs enable more versatile and simpler programming of protection parameters, such as overcurrent threshold and start-up time. Thanks to their Enable/fault pins, hot-swap power management ICs can be remotely reset after a fault, which helps to drastically reduce the number of false-faults and equipment downtime.
Within its hot-swap power management family, ST offers three main kinds of hot-swap controllers:
