Dual-channel 4.5A /16mΩ Integrated Power Switch

June 30, 2015 by Jeff Shepard

Silego Technology today announced a new addition to its expanding dual-channel, self-contained integrated power-switch product portfolio. Adding reverse-current blocking to its feature set, the SLG59M1603V is optimized for low-voltage power-rail distribution, power-rail sequencing, or any other two-power-rail application where power flow from load to source cannot be allowed. The SLG59M1603V operates from 2.5V to 5V and, because of its proprietary and patented CuFET™ technology, is designed to handle continuous load currents up to 4.5A per channel in a small footprint TDFN package. Target applications include: power-rail sequencing, two-rail power multiplexing, notebook and tablet PCs, multifunction printers, embedded PCs and similar systems.

With internal charge pumps, output discharge circuitry, and separate ON/OFF controls, both channels of the SLG59M1603V are completely independent of each other. As a result, each channel of this highly-integrated power switch can be configured for different power-rail applications without affecting the operation of the opposite channel.

Also by virtue of the company’s CuFET™ technology, both channels can be combined in parallel for higher-current applications up to the total power dissipation of the package or up to 8.5 A, whichever is lower. Available in a space-saving 14-pin 1.0 x 3.0 mm STDFN package, the SLG59M1603V is fully specified from -40 to 85 degrees C.

Key SLG59M1603 specifications include: Ultra-low RDSON: 16 mΩ per Channel; Continuous Load Current: Up to 4.5 A per Channel; VDD Supply Voltage Range: 2.5 V to 5.5 V; Wide Power-rail Voltage Range: 1 V to VDD; Low Reverse-current Leakage when OFF: 0.5 µA; Adjustable In-rush Current/VOUT Slew Rate Control via External Capacitor; Over-temperature Protection; Low Operating Supply Current: 50 µA; Low-Supply Current when OFF: 1 µA; and Fast, Internal Discharge.
