RT9705B - 1A Power Multiplexer

Datasheet Summary

Features

  • The RT9705B is a dual input single output power multiplexer specifically designed to provide seamless voltage transition between two independent power suppliers. Equipped with two low RDS(ON) N-Channel MOSFETs driven by internal charge pump circuitry, the RT9705B is able to deliver 1A output current with only 80mV voltage drop. Manual or auto switching mode is easily selected by two digital inputs D1 and D0. When both D0 and D1 are selected high, the RT9705B enters shutdown mode and consumes mi.

RT9705B 80mΩ, 1A Power Multiplexer General Description Features The RT9705B is a dual input single output power multiplexer specifically designed to provide seamless voltage transition between two independent power suppliers. Equipped with two low RDS(ON) N-Channel MOSFETs driven by internal charge pump circuitry, the RT9705B is able to deliver 1A output current with only 80mV voltage drop. Manual or auto switching mode is easily selected by two digital inputs D1 and D0. When both D0 and D1 are selected high, the RT9705B enters shutdown mode and consumes minimum power making it ideal suitable for battery powered equipments. A STAT pin with open drain output is provided to indicate the switch status. A user-programmable up to 1.
