TPS2393EVM 描述
The TPS2392 and TPS2393 integrated circuits are hot swap power managers optimized for use in nominal -48 V systems. They operate over a supply voltage range of -20 V to -80 V, and are rated to withstand spikes to -100 V. In conjunction with an external N-channel FET and sense resistor, they can be used to enable live insertion of plug-in cards and modules in powered systems. Each device provides load current slew rate control and peak magnitude limiting. Undervoltage and overvoltage shutdown thresholds are easily programmed via a three-resistor divider network.
This User's Guide describes the use and features of the full-featured -48 V hot swap evaluation module (EVM). This EVM can be used to learn about the TPS2392 and TPS2393 hot swap power manager (HSPM) integrated circuits from Texas Instruments. The TPS2392 and TPS2393 are negative voltage hot swap controllers intended for use in systems needing to hot swap telecom distribution-level voltages. They integrate inrush current control, peak current limiting, electronic circuit breaker, enable input, powergood reporting, overvoltage and undervoltage protection, debounced insertion detection, and current fault indication. The EVM is a PCB-based tool featuring either device, and can be used to evaluate device operation in simulated live insertion events.
