The TPS2561-Q1 is a dual-channel power-distribution switch intended for applications where precision current limiting is required or heavy capacitive loads and short circuits are encountered. These devices offer a programmable current-limit threshold between 250 mA and 2.8 A (typ) per channel through an external resistor. The power-switch rise and fall times are controlled to minimize current surges during turn on or off.

Each channel of the TPS2561-Q1 device limits the output current to a safe level by switching into a constant-current mode when the output load exceeds the current-limit threshold. The FAULTx logic output for each channel independently asserts low during overcurrent and over temperature conditions.

TPS2561DRCEVM-424 — TPS2561DRCEVM-424：用於 TPS2561 的評估模組

The TPS2560EVM-424 and TPS2561EVM-424 are evaluation modules (EVM) for Texas Instruments power-distribution switches with adjustable current-limit. These EVMs operate over a 2.5-V to 6.5-V range. An on-board jumper sets the output current-limit to either 0.5 A or 1 A. The board is designed for the (...)
