Page 2: Introduction
1 Introduction The TPS3899EVM is an evaluation module (EVM) for the TPS3899 voltage supervisor. The TPS3899EVM can be used with any TPS3899 device variant but please note that if using the push-pull variants (TPS3899PLXX or TPS3899PHXX), the shunt on J4 must be removed as push-pull devices do not use a pull-up resistor and R1 must be disconnected. -

Figure 4-3 shows a programmable push-button circuit that has a programmable holding condition and a programmable output width. The TPS3899EVM supports testing for programmable push-button functionality. This is accomplished using a shunt on jumper J5 (RESET [pin 4] to R [pin 3]). - Page 12 STANDARD TERMS FOR EVALUATION MODULES Delivery: TI delivers TI evaluation boards, kits, or modules, including any accompanying demonstration software, components, and/or documentation which may be provided together or separately (collectively, an “EVM” or “EVMs”) to the User (“User”) in accordance with the terms set forth herein.
