It is designed to provide robust power path protection in industrial systems operating from 4.5V to 60V supply rails. The device integrates a 31m\u03a9 hot-swap MOSFET, eliminating the need for an external power switch and significantly reducing solution footprint compared to traditional hot-swap controller plus external FET architectures. The TPS26630 variant features adjustable overvoltage cutoff and active current limiting at 1\u00d7 IOL without pulse overcurrent support. A key differentiator is the device's ability to achieve IEC 61000-4-5 Class-A system performance during surge events, enabled by its fast reverse current blocking capability (0.17\u00b5s) and B-FET driver for external blocking FETs. The integrated thermal regulation loop allows reliable startup even with large and unknown capacitive loads, while the analog current monitor output (IMON) provides real-time load current visibility with \u00b16% accuracy. Target applications include PLCs, industrial PCs, servo drives, and any 24V\/48V industrial system requiring comprehensive power path protection with regulatory compliance.","working_principle":"The TPS26630RGET operates as a fully integrated power path protector with three core subsystems:\n\n1. **Hot-Swap and Inrush Control Subsystem**: At power-up, the internal FET is controlled by the dVdT slew rate circuit. An external capacitor on the dVdT pin sets the output voltage ramp rate, limiting inrush current to charge downstream capacitors. The thermal regulation loop monitors die temperature and modulates the FET gate drive to keep junction temperature within safe limits during startup with large capacitive loads.\n\n2. **Overcurrent and Short-Circuit Protection Subsystem**: The current limit is set by an external resistor on the ILIM pin (RILIM \u2265 3k\u03a9), establishing a threshold from 0.6A to 6A with \u00b17% accuracy. During overload, the device actively limits current to the programmed threshold. During a hard short circuit, the fast-acting comparator trips within microseconds to protect downstream circuitry. The MODE pin selects between latch-off and auto-retry fault responses.\n\n3. **Voltage Supervision and Reverse Protection Subsystem**: Adjustable UVLO and OVP circuits monitor the input voltage via resistor dividers on the UVLO and OVP pins, disconnecting the load when input voltage falls outside the programmed window. The B-FET driver controls an external N-channel FET for reverse polarity protection and reverse current blocking in 0.17\u00b5s. The PGOOD output signals when the output voltage is valid, enabling coordinated startup of downstream DC-DC converters.","pin_description":"
