Description
The MAX5910/MAX5917 are fully integrated hot-swap switches for positive supply rails. These devices allow the safe insertion and removal of circuit cards into live backplanes or ports without causing glitches on the backplane power-supply rail. They also monitor various circuit parameters and disconnect the load if a fault condition occurs, alerting the host with a logic-level active-low IFAULT output. The MAX5910/MAX5917 operate over a +10V to +65V input voltage range. They are designed to permit hot plugging of an internet appliance such as an IP phone but are not limited to that application.

During startup, an internal power FET regulates the current between the backplane power source and the load to 280mA for the MAX5910, 567mA for the MAX5917A, and 420mA for the MAX5917B. After startup, the FET is fully enhanced to reduce its on-resistance. To ensure robust operation, the MAX5910/MAX5917 contain built-in safety features that prevent damage to the internal FET. They include an enable input, which responds to positive logic signals (+3.3V or +5V), allowing the host system to disconnect the load.

The MAX5910/MAX5917 Simple Swapper™ hot-swap ICs monitor four parameters for fault conditions: undervoltage lockout (UVLO), power-not-good, zero-current detection, and thermal shutdown. These devices are available in the extended temperature range, -40°C to +85°C. The MAX5910 comes in an 8-pin SO package and the MAX5917A/B is available in a 16-pin SO package.
