TPS22965DSGT Load Switch: Layout, Pinout, and Datasheet

The TPS22965DSGT is a single-channel load switch with adjustable rise time to reduce inrush current. An N-channel MOSFET is included in the device, which can function between 0.8 and 5.7 V and handle a maximum continuous current of 6 A. An on/off input (ON) controls the switch and is capable of interacting directly with low-voltage control signals. A 225-ohm on-chip load resistor is included in the TPS22965DSGT, allowing for rapid output discharge when the switch is switched off.

The TPS22965DSGT is supplied in a 2-mm*2-mm 8-pin SON package ( DSG ) with an integrated thermal pad for high power dissipation. The gadget is designed to operate in a temperature range of –40°C to +105°C in free air.

The following figure is TPS22965DSGT Simplified Schematic.

Simplified Schematic

All traces must be as brief as possible for optimal performance. In order to reduce the impacts of parasitic trace inductances on normal operation, the input and output capacitors must be located close to the device. The use of large traces for VIN, VOUT, and GND reduces parasitic electrical effects while also lowering case-to-ambient thermal impedance. To avoid parasitic capacitance, the CT trace must be as short as feasible.
