TPS3780EVM-154 Evaluation Module
This user's guide describes the operational use of the TPS3780EVM-154 evaluation module (EVM) as a
reference design for engineering demonstration and evaluation of the TPS3780EVM, two-channel voltage
detectors with low-power and high-accuracy comparators. 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 evaluation module. This user's guide also discusses how to modify the TPS3780EVM-154 board to
evaluate the TPS3779.

Page 2: Introduction
Introduction www.ti.com Introduction The Texas Instruments TPS3780EVM-154 helps design engineers evaluate the operation and performance of two TPS3780 ICs with different hysteresis options (TPS3780ADRYR/T and TPS3780BDRYR/T) for possible use in their own circuit application. This particular EVM configuration contains two dual-voltage detectors with low quiescent current and high threshold accuracy in a small µSON (1.45 mm ×... -

TPS3780 perform the same functions; however, they use different output stages. The TPS3780 uses an open-drain output while the TPS3779 uses a push-pull output. Modifying the TPS3780EVM-154 Board The TPS3779 uses a push-pull output stage; therefore, pullup resistors are not needed. The following modifications to the TPS3780EVM-154 board can be made to evaluate the TPS3779: •... - Page 6 Changed Table 3 ..........• Changed modification steps in Modifying the TPS3780EVM-154 Board section NOTE: Page numbers for previous revisions may differ from page numbers in the current version.
