MAX15096A：2.7V to 18V, 6A Integrated Hot-Swap/Electronic Circuit Breaker

2.7V-18V Input, Smallest 6A Hot-Swap Solution with Only 12mΩ RDSON and 10% Circuit Breaker Threshold Accuracy

The MAX15096/MAX15096A/MAX15096D ICs 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, 12mΩ (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 (MAX15096) or automatic retry (MAX15096A); the output could also be discharged after a fault event (MAX15096D). 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 16-bump, 2mm x 2mm wafer-level package (WLP) and are rated over the -40°C to +105°C extended temperature range.
