SLG59M1598V SLG59M1598V An Ultra-small, 17 m, 2.5 A Load Switch with Discharge General Description Pin Configuration The SLG59M1598V is a 17 m 2.5 A single-channel load switch that is able to switch 0.85 V to 5.5 V power rails. The product is packaged in an ultra-small 1.0 x 1.6 mm package. 1 8 VDD GND Features 1.0 x 1.6 x 0.55 mm STDFN package (2 fused pins for 2 7 ON CAP drain and 2 fused pins for source) 6 D 3 Logic level ON pin capable of supporting 0.85 V CMOS S Logic 5 D 4 S User selectable ramp rate with external capacitor 17 mRDS while supporting 2.5 A ON Discharges load when off 8-pin STDFN Two Over Current Protection Modes (Top View) Short Circuit Current Limit Active Current Limit Over Temperature Protection Pb-Free / Halogen-Free / RoHS compliant Applications Operating Temperature: -40 C to 85 C Notebook Power Rail Switching Operating Voltage: 2.5 V to 5.5 V Tablet Power Rail Switching Smartphone Power Rail Switching Block Diagram 2.5 A 17 m D S VDD C C IN LOAD +2.5 to 5.5 V Charge Pump Linear Ramp Control CAP C SLEW 4 nF Over Current and Over Temperature Protection ON CMOS Input Datasheet Revision 1.04 26-Jun-2019 Page 1 of 14 2019 Dialog Semiconductor CFR0011-120-01SLG59M1598V An Ultra-small, 17 m, 2.5 A Load Switch with Discharge Pin Description Pin Pin Name Type Pin Description VDD supplies the power for the operation of the power switch and internal control circuitry. 1 VDD PWR Bypass the VDD pin to GND with a 0.1 F (or larger) capacitor. A low-to-high transition on this pin initiates the operation of the SLG59M1598Vs state machine. ON is a CMOS input with ON V < 0.3 V and ON V > 0.85 V thresholds. While IL IH 2 ON Input there is an internal pull-down circuit to GND (~4 M), connect this pin directly to a general-purpose output (GPO) of a microcontroller, an application processor, or a system controller. Drain terminal connection of the n-channel MOSFET (2 pins fused for D). Connect at least 3, 4 D MOSFET a low-ESR 0.1 F capacitor from this pin to ground. Capacitors used at D should be rated at 10 V or higher. Source terminal connection of the n-channel MOSFET (2 pins fused for S). Connect a 5, 6 S MOSFET low-ESR capacitor from this pin to ground and consult the Electrical Characteristics table for recommended C range. Capacitors used at S should be rated at 10 V or higher. LOAD A low-ESR, stable dielectric, ceramic surface-mount capacitor connected from CAP pin to GND sets the V slew rate and overall turn-on time of the SLG59M1598V. For best S 7 CAP Input performance C value should be 1.5 nF and voltage level should be rated at 10 V or SLEW higher. 8 GND GND Ground connection. Connect this pin to system analog or power ground plane.
