SLG59M1730C SLG59M1730C An Ultra-small 33 m , 1.0 A pFET Integrated Power Switch with Controlled Inrush Current General Description Pin Configuration Pin A1 Index Mark Operating from a 2.5 V to 5.5 V power supply, the SLG59M1730C is a self-powered, high-performance 33 m , 12 1.0 A single-channel pFET integrated power switch with a A ON GND controlled V inrush current profile. The SLG59M1730Cs low IN supply current and controlled V inrush current profile makes IN it an ideal pFET integrated power switch in small form-factor B VIN VOUT personal health monitor and watch applications. Using a proprietary MOSFET design, the SLG59M1730C achieves a low RDS across the entire input voltage range. ON 4L WLCSP Through the application of Silegos proprietary CuFET (Laser Marking View) technology, the SLG59M1730Cs can be used in applications 2 up to 1 A with a very-small 0.64 mm WLCSP form factor.

Rev 1.04 000-0059M1730-104 Revised October 24, 2017 SLG59M1730C Pin Description Pin Pin Name Type Pin Description A low-to-high transition on this pin initiates the operation of the SLG59M1730C. ON is an asserted HIGH, level-sensitive CMOS input with V < 0.3 V and V > 0.85 V. As IL IH the ON pin input circuit does not have an internal pull-down resistor, connect this pin A1 ON Input to a general-purpose output (GPO) of a microcontroller, an application processor, or a system controller do not allow this pin to be open-circuited. In order to activate the SLG59M1730Cs controlled inrush current control circuitry, ON shall be toggled HIGH only after V is higher than the SLG59M1730Cs V specification. IN SUCC(TH) Input terminal connection of the p-channel MOSFET. Connect a 10 F (or larger) B1 VIN MOSFET low-ESR capacitor from this pin to ground. Capacitors used at VIN should be rated at 10 V or higher. Output terminal connection of the p-channel MOSFET. For optimal operation of the B2 VOUT MOSFET SLG59M1730C controlled inrush current profile, connect a 30 F (or smaller) capacitor from this pin to ground. Capacitors used at VOUT should be rated at 10 V or higher. A2 GND GND Ground connection. Connect this pin to system analog or power ground plane.
