RT9731B Overview
The RT9731A/B 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. This device offers a programmable current limit threshold between 560mA and 2.8A (typ.) per channel via an external resistor. The power-switch's rising and falling times are controlled to minimize current surges during on/off...
