A low-to-high transition on this pin initiates the operation of the SLG59M1457Vs 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 SLG59M1457V. 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.
