The TPS37AQ1EVM helps design engineers to evaluate the operation and performance of the TPS37x-Q1/TPS38x-Q1 family of overvoltage and undervoltage monitors for possible use in their own circuit applications. This particular EVM configuration contains the TPS37A010122DSKRQ1, an overvoltage and undervoltage supervisor designed to monitor an adjustable rail with support for voltage dividers down to a 0.8V threshold voltage. The family of TPS37x-Q1/TPS38x-Q1 provides variable thresholds from 2.7 V to 36V and hysteresis options from 2% to 13% in a small 10-pin WSON package with both open-drain output and push-pull outputs. The TPS37x-Q1/TPS38x-Q1 family includes adjustable capacitor pins for tying capacitors to adjust delays on both the rising and falling edges of the RESET outputs. Separately available SENSE input pins allow the redundancy sought by safety-critical and high-reliability systems. Lastly, the device provides an optional manual reset that allows a hard reset and a latch feature for certain desired applications. Section 2 provides schematics, a BOM, and layout information on the board. Section 3 describes the connectors, jumpers, and test points for the device. Section 4 describes the setup and operation of the EVM.
