The is a Power Distribution Switch is designed to fulfill the applications in heavy capacitive loads and short-circuit situations. The device incorporates two 90mR N-MOSFET power switches to fit power distribution systems. During switching process, an internal charge pump is designed to provide the gate drive for the purpose of power-switch rise times and fall times controlling to minimize the current surges. The charge pump can operate in supply voltage as low as 2.7V and needs no external components. If the output load exceeds the current-limit threshold or a short-circuit occurs. The RT9712 series pull the overcurrent FLGx logic output low by switching into the constant-current mode to maintain the output current in a safe level, A thermal protection circuit turns off the switch to prevent the device from damage when power dissipation is increased by continuous heavy overloads and short-circuits in the switch and finally cause the rise of the junction temperature.
