Description
The MAX15095 family of devices are integrated solutions for hot-swap applications requiring the safe insertion and removal of circuit line cards from a live backplane. They can also be used as electronics circuit breaker for hard drive and solid-state drive and fans. The devices integrate a hot-swap controller (10.6mΩ typ) power MOSFET, and an electronic circuit-breaker protection in a single package.
The devices are designed for protection of 2.7V to 18V supply voltages. These devices implement a foldback current limit during startup to control inrush current, lowering di/dt and keeping the MOSFET operating under safe operating area (SOA) conditions. After the startup cycle is complete, on-chip comparators provide VariableSpeed/BiLevel™ protection against short-circuit and overcurrent faults, and immunity against system noise and load transients. The load is disconnected in the event of a fault condition. The devices are factory calibrated to deliver accurate overcurrent protection with ±10% accuracy. During a fault condition, PG goes low and the devices latch off (MAX15095) or automatic retry (MAX15095A); the output could also be discharged after a fault event (MAX15095D).
The devices feature an IN-to-OUT short-circuit detection before startup. The devices provide a power-MOSFET GATE pin to program the slew rate during startup by adding an external capacitor. The devices have an undervoltage/overvoltage input pin (UVOV) that can detect an undervoltage/overvoltage fault and disconnect the IN from the OUT. Additional features include internal overtemperature protection and a power-good output (PG).
The devices are available in a 12-pin, 2.5mm x 2.5mm Flip Chip 2 QFN package (FC2QFN) and are rated over the -40°C to +105°C extended temperature range.
