Introduction
1.1
Description
The TPS22810EVM is a two-layer PCB containing the TPS22810 load switch device. The TPS22810EVM
supports two packages for TPS22810 device, SOT-23 package (DBV) on CH1 and SON package (DRV)
on CH2. The VIN and VOUT connections to the device and the PCB layout routing are capable of
handling high continuous currents and provide a low-resistance pathway into and out of the device under
test. Test point connections allow the EVM user to control the device with user-defined test conditions and
make accurate RON measurements.
1.2
Features
This EVM has the following features:
V
input voltage range: 2.7 to 18 V
IN
Access to the VIN, VOUT, CT, QOD, GND, and EN pins of the TPS22810 load switch device

    Connect the VIN power supply to the T1/T3 terminal (VIN1/VIN2). The input voltage range of the TPS22810EVM is 2.7 to 18 V. External output loads can be applied to the load switch by using the T2/T4 terminal (VOUT1/VOUT2). The TPS22810 is active high device, and EN/UVLO pin must not be left floating.
