SLG59M1736C SLG59M1736C An Ultra-small 33 m, 2.2 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 SLG59M1736C is a self-powered, high-performance 33 m, 12 2.2 A single-channel pFET integrated power switch with a A ON GND controlled V inrush current profile. The SLG59M1736Cs 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 SLG59M1736C achieves a low RDS across the entire input voltage range. ON 4L WLCSP Through the application of Dialogs proprietary CuFET (Laser Marking View) technology, the SLG59M1736C can be used in applications up 2 to 2.2 A with a very-small 0.64 mm WLCSP form factor.

ON is an asserted HIGH, level-sensitive CMOS input with ON V < 0.3 V and IL ON V > 0.85 V. As the ON pin input circuit does not have an internal pull-down IH resistor, connect this pin to a general-purpose output (GPO) of a microcontroller, an A1 ON Input application processor, or a system controller do not allow this pin to be open-circuited. In order to activate the SLG59M1736Cs controlled inrush current control circuitry, ON shall be toggled HIGH only after V is higher than the SLG59M1736Cs V IN SUCC(TH) specification. 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 SLG59M1736C 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 VOUT Ground connection. Connect this pin to system analog or power ground plane.
