SLG59M1545V SLG59M1545V An Ultra-small, 17 m, 2.5 A Load Switch General Description Pin Configuration The SLG59M1545V 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 Two Over Current Protection Modes 8-pin STDFN Short Circuit Current Limit (Top View) Active Current Limit Over Temperature Protection Pb-Free / Halogen-Free / RoHS compliant Operating Temperature: -20 C to 70 C Applications Operating Voltage: 2.5 V to 5.5 V Notebook Power Rail Switching 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 1.02 7-Nov-2019 Page 1 of 14 2019 Dialog Semiconductor CFR0011-120-01SLG59M1545V An Ultra-small, 17 m, 2.5 A Load Switch Pin Description Pin Pin Name Type Pin Description VDD supplies the power for the operation of the power switch and internal control circuitry. 1VDD 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 SLG59M1545Vs state machine. ON is a CMOS input with ON V < 0.3 V and ON V > 0.85 V thresholds. While IL IH there is an internal pull-down circuit to GND (~4 M), connect this pin directly to a 2 ON Input 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 SLG59M1545V. 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.
