Ω, 1A Power Multiplexer

General Description

The RT9705 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 RT9705 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

RT9705 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

1.25A current limit function is available for maximum safety

in various applications.

The RT9705 provides comprehensive protection functions,

including adjustable current limit, over temperature

protection, soft start function for minimum inrush current,

cross-conduction protection, and reverse conduction

protection. These features greatly simplify power

multiplexer design. The RT9705 is available in TSSOP-8

package requiring minimum board area and smallest

components.
