Overview
The TPS22810DRVR from Texas Instruments is a single-channel load switch designed with advanced features to manage power distribution efficiently. It integrates a configurable rise time and an adjustable quick output discharge (QOD) function, making it suitable for a wide range of applications. The device operates over an input voltage range of 2.7 V to 18 V and is available in two package options: SOT23-6 (DBV) and WSON (DRV), supporting maximum continuous currents of 2 A and 3 A, respectively. The TPS22810DRVR includes thermal shutdown, undervoltage lock-out (UVLO), and low on-resistance, ensuring reliable operation across various environmental conditions.

Q & A
- What is the input voltage range of the TPS22810DRVR? The input voltage range is 2.7 V to 18 V.
- What are the maximum continuous current ratings for the DBV and DRV packages? The DBV package supports up to 2 A, and the DRV package supports up to 3 A.
- What is the typical on-resistance of the TPS22810DRVR at VIN = 12 V? The typical on-resistance is 79 mΩ.
- Does the TPS22810DRVR have thermal protection? Yes, it features thermal shutdown to protect against high junction temperatures.
- How is the quick output discharge (QOD) function configured? The QOD pin can be configured by shorting it to VOUT, using an external resistor, or leaving it floating.
- What is the ambient operating temperature range of the TPS22810DRVR? The device operates from –40°C to +105°C.
- What are the ESD performance ratings of the TPS22810DRVR? The device is tested per JESD 22 with ratings of ±2-kV HBM and ±1-kV CDM.
- Can the EN/UVLO pin be left floating? No, the EN/UVLO pin must be driven either high or low for proper functionality.
