SBVU023 – August 2014 TPS3847085EVM-577 Evaluation Module This user’s guide describes the operational use of the TPS3847085EVM-577 evaluation module (EVM) as a reference design for engineering demonstration and evaluation of the TPS3847085, an ultralow-power, wide supply voltage, supervisory circuit. Included in this user’s guide are setup instructions, a schematic diagram, printed circuit board (PCB) layout drawings, and a bill of materials for the EVM. - Page 2 Introduction The Texas Instruments TPS3847085EVM-577 EVM helps design engineers to evaluate the operation and performance of the TPS3847xxx family of supervisors for possible use in their own circuit applications. This particular EVM configuration contains the TPS3847085 supervisor with an internal push-pull RESET output, in a 5-pin, DBV (SOT-23) package.

Page 3: Setup And Test
Operation The TPS3847085EVM-577 is a fixed, single-rail monitor, and triggers a reset when its own supply rail VDD falls below the set threshold of 8.5 V. An internal push-pull RESET circuit eliminates the need for a pull-up resistor. -
