Overview
The TPS22965DSGT is a single-channel load switch produced by Texas Instruments. This device is designed to provide a high-current switching solution with ultra-low on-resistance and adjustable rise time to minimize inrush current. The TPS22965DSGT features an N-channel MOSFET that can operate over an input voltage range of 0.8 V to 5.7 V and support a maximum continuous current of 6 A. It is controlled by an active high on/off input (ON) that is compatible with low-voltage control signals. The device is packaged in a small, space-saving 2-mm × 2-mm 8-pin SON package with an integrated thermal pad for high power dissipation and is characterized for operation over a temperature range of -40°C to +105°C.

- What is the operating temperature range of the TPS22965DSGT?
The operating temperature range is from -40°C to +105°C.
- What type of package does the TPS22965DSGT come in?
The device is packaged in an 8-pin SON package with an integrated thermal pad.
- What are the ESD ratings for the TPS22965DSGT?
The ESD ratings are ±2000 V for HBM and ±1000 V for CDM.
- How does the TPS22965DSGT reduce inrush current?
The device reduces inrush current through its adjustable rise time feature, controlled by a capacitor on the CT pin.
- What is the recommended input capacitor configuration for minimizing VIN dip?
A 1-µF ceramic capacitor (CIN) placed close to the VIN and GND pins is recommended, with higher values possible for further reduction in voltage drop.
- Can the ON pin be left floating?
No, the ON pin must be driven either high or low for proper functionality and cannot be left floating.
