SLG7NT402V SLG7NT402V 2 An Ultra-small 3 mm , 8.5 m, 4 A, Internally-protected Integrated Power Switch General Description Pin Configuration The SLG7NT402V is a high performance 8.5 m, 4 A single-channel nFET integrated power switch which can operate with a 2.5 V to 5.5 V V supply to switch power rails DD from as low as 0.85 V up to the supply voltage. The 1 8 VDD GND SLG7NT402V incorporates two-level overload current 2 7 ON CAP protection, thermal shutdown protection, and inrush current control which can easily be adjusted by a small external 6 D 3 S capacitor. 5 Using a proprietary MOSFET design, the SLG7NT402V D 4 S achieves a stable 8.5 m RDS across a wide input voltage ON range. In addition, the SLG7NT402Vs package also exhibits 8-pin FC-TDFN low thermal resistance for high-current operation using Dialogs advanced assembly technology. (Top View) Fully specified over the -40 C to 85 C temperature range, the SLG7NT402V is packaged in a space-efficient, low thermal resistance, RoHS-compliant 1.5 mm x 2.0 mm STDFN Applications package.

A low-to-high transition on this pin initiates the operation of the SLG7NT402Vs 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 V ). Connect at least D 3, 4 D MOSFET a low-ESR 0.1 F capacitor from this pin to ground. Capacitors used at V should be rated D at 10 V or higher. Source terminal connection of the n-channel MOSFET (2 pins fused for V ). Connect a S 5, 6 S MOSFET low-ESR capacitor from this pin to ground and consult the Electrical Characteristics table range. Capacitors used at V should be rated at 10 V or higher. for recommended C LOAD S 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 SLG7NT402V. 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.
