Connect a 10 F (or larger) low ESR 1, 2 D1 MOSFET capacitor from this pin to GND. Capacitors used at D1 should be rated at 10 V or higher. A low-to-high transition on this pin closes the Channel 1 of power switch. ON1 is an assert- ed-HIGH, level-sensitive CMOS input with ON V < 0.3 V and ON V > 0.85 V. Connect IL IH this pin to the output of a general-purpose output (GPO) from a microcontroller or other 3 ON1 Input application processor. While there is an internal pull down circuit to ground (~4 M), it is allowed this pin to be open-circuited. VDD supplies the power for the operation of the power switch and internal control circuitry 4VDD VDD where its range is 2.5 V V 5.5 V. Bypass the VDD pin to GND with a 0.1 F (or larger) DD capacitor. A low-to-high transition on this pin closes the Channel 2 of power switch. ON2 is an assert- ed-HIGH, level-sensitive CMOS input with ON V < 0.3 V and ON V > 0.85 V. Connect IL IH 5 ON2 Input this pin to the output of a general-purpose output (GPO) from a microcontroller or other application processor. While there is an internal pull down circuit to ground (~4 M), it is allowed this pin to be open-circuited. Drain/Input terminal of Power MOSFET Channel 2. Connect a 10 F (or larger) low ESR 6, 7 D2 MOSFET capacitor from this pin to GND. Capacitors used at D2 should be rated at 10 V or higher. Source/Output terminal of Power MOSFET Channel 2. Connect a 10 F (or larger) low ESR 8, 9 S2 MOSFET capacitor from this pin to GND. Capacitors used at S2 should be rated at 10 V or higher. A low-ESR, stable dielectric, ceramic surface-mount capacitor connected from CAP2 pin to GND, sets the V slew rate and overall turn on time of the SLG59M1527V. For best S2 10 CAP2 Input performance, the range for C values are 1 nF C 22 nF. Capacitors used at SLEW SLEW the CAP2 pin should be rated at 10V or higher. 11 GND GND Ground connection. Connect this pin to system analog or power ground plane. A low-ESR, stable dielectric, ceramic surface-mount capacitor connected from CAP1 pin to GND, sets the V slew rate and overall turn on time of the SLG59M1527V. For best S1 12 CAP1 Input performance, the range for C values are 1 nF C 22 nF. Capacitors used at SLEW SLEW the CAP1 pin should be rated at 10V or higher. Source/Output terminal of Power MOSFET Channel 1. Connect a 10 F (or larger) low ESR 13, 14 S1 MOSFET capacitor from this pin to GND. Capacitors used at S1 should be rated at 10 V or higher.
