NPS3102
12 V, 2 A to 13.5 A, 17 mΩ eFuse
NPS3102A and NPS3102B are low-ohmic (17 m?), high current (13.5 A), resettable electronic fuses that are targeted for 12 V applications. They are designed to protect downstream loads from exposure to excessive voltage and protect the power supply from load faults and large inrush currents.
Output slew rate is controlled by a capacitor at dVdt pin. Current limit can be adjusted in the 2 A to 13.5 A range using a resistor at ILIM pin. The voltage at ILIM pin can also be used as a measure of the load current in real-time. The devices include a built-in over voltage clamp that will limit the output voltage during input over voltage conditions.
The devices also include a multi-function EN/FLT pin. When the pin is left floating and the voltage at IN is greater than the under voltage lock-out, the devices turn on. During operation, the voltage at the pin can be used as a fault indicator to determine if the devices are operating normally. Pulling the EN/FLT pin low will turn off the devices.
During thermal shutdown, both devices disable the integrated pass-FET if the die temperature crosses the over temperature threshold. The NPS3102A latches off under a thermal shutdown event and requires user reset by toggling the EN/FLT pin or cycling the voltage at the IN pin. The NPS3102B integrates auto-retry, which safely attempts to re-enable the pass-FET without the need for user intervention.
