Page 2: Introduction
Introduction www.ti.com Introduction The Texas Instruments' TPS3702CX33EVM-683 EVM helps design engineers to evaluate the operation and performance of the TPS3702 family of overvoltage and undervoltage monitors for possible use in their own circuit applications. This particular EVM configuration contains the TPS3702CX33 window voltage detector for overvoltage and undervoltage monitoring with open-drain output, in a 6-pin, DDC (SOT) package. -

The R4 (3.3-MΩ) and R5 (1.8-MΩ) resistors are used to safeguard the SET pin when JP1 is set to VCC. These resistors form a resistor divider connected between VCC and GND.

10. Vary the power supplies connected to OV PU and UV PU as necessary for test purposes. Operation The TPS3702CX33EVM-683 is a fixed-threshold, single-rail monitor, and triggers a reset when the monitored supply rail connected to SENSE exits the accuracy band. Pull-up resistors are used to generate the overvoltage and undervoltage signals. -
