This section describes the functionality and operation of the TPS3704Q1EVM. Refer to the TPS3704x-Q1 datasheet for details on the electrical characteristics of the device.
The TPS3704Q1EVM comes pre-populated with the TPS37044A7OHDDFRQ1 meaning the device is capable of monitoring four seperate voltage rails and outputting two active low RESET signals. The EVM is capable of many different configurations in order to fully evaluate the functionality of all the TPS3704x-Q1 device variants. The default configuration of the EVM is as follows:
The TPS3704Q1EVM comes populated with 2:1 resistor dividers on each of the input lines. The user must choose appropriately sized resistors such that the divided voltage is within the voltage window of the sense pin to be used. Consult the Device Threshold Table in the datasheet to ensure proper resistor values.
The TPS3704Q1EVM also provides an option to apply a seperate pull-up voltage to any of the output pins by changing the position of jumpers J9, J10, and/or J11 to EXT and connecting the pull-up voltage to test points TP8, TP9, and/or TP10.
