BQ25504EVM-674 Datasheet PDF - TI

BQ25504EVM-674 is a Ultra Low Power Boost Converter with battery management for energy harvester applications. This EVM is programmed from the factory for settings compatible with most MCU"s and 3V coin cell batteries. The EVM is programmed to deliver a 3.1VDC maximum voltage (OV) for charging the storage element and the under voltage is programmed to 2.2VDC. The VBAT_OK indication toggles high when VSTOR ramps up at 2.8VDC and when VSTOR ramps down to 2.4VDC. The user"s guide describes the bq25504 evaluation module (EVM), how to perform a stand-alone evaluation and allows the EVM to interface with the system and host.
