11.3.1.2.1 Setting Voltage Threshold

The positive-going threshold voltage, VITP, is set by the device variant. In this example, the nominal supply voltage from the battery is 12V. Setting a overvoltage threshold of 30V makes sure that the device resets before supply voltage violates the allowed boundary. The adjustable voltage variant is chosen and R1 and R2 are adjusted to meet the threshold. Assuming R2 equal to 10kΩ and R1 is calculated as 365kΩ. For additional information on selecting resistor values see Section 11.2. TPS3762-Q1 also supports fixed voltage threshold variants. Threshold voltage decoding can be found in Device Decoder.
