TPS2561ADRCT

双通道精密可调电流限制电源开关 Dual Channel Precision Adjustable Current-Limited Power Switches

DESCRIPON

The TPS2560A and TPS2561A are dual-channel power-distribution switches 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 via an external resistor. The power-switch rise and fall times are controlled to minimize current surges during turn on/off.
