Introduction

AI Translation

The MAX5902/MAX5903 are hot-swap controllers that allow a circuit card to be safely hot plugged into a live backplane without causing a glitch on the power-supply rail. These devices operate from +9V to +72V and provide the simplest hot-swap solution by eliminating all external components except the external p-channel MOSFET. The MAX5902/MAX5903 limit the inrush current to the load and provide a circuit-breaker function for overcurrent protection. During startup the circuit-breaker function is disabled and the MAX5902/MAX5903 limit the inrush current by gradually turning on the external MOSFET. Once the external MOSFET is fully enhanced, the circuit-breaker function is enabled and the MAX5902/MAX5903 provide overcurrent protection by monitoring the voltage drop across the external MOSFET’s on-resistance. The MAX5902/MAX5903 include an undervoltage lockout (UVLO) function, ON/OFF control input, and a power-good status output, PGOOD (MAX5902) or PGOOD (MAX5903). A built-in thermal shutdown feature is also included to protect the external MOSFET in case of overheating. The MAX5902/MAX5903 offer latched or autoretry fault management and are available with 300mV, 400mV or 500mV circuit-breaker thresholds. Both the MAX5902 and MAX5903 are available in small SOT23 and TDFN packages, and are specified for the extended -40℃ to +85℃ temperature range.

The MAX5902/MAX5903 are integrated hot-swap controller ICs contained in 6-pin SOT23 and TDFN packages. They allow a board to be safely hot-plugged into a live backplane without causing a glitch on the powersupply rail. They are well suited for +48V power systems allowing cost-effective, simple, and compact design. The MAX5902/MAX5903 operate from +9V to +72V to cover a wide range of end equipment hot-swap needs.
