Texas Instruments BQ25790EVM Evaluation Module

Texas Instruments BQ25790EVM Evaluation Module is a fully assembled and tested circuit for evaluating the BQ25790 integrated switched-mode buck-boost battery charge management device in the (WCSP) DSBGA package. The BQ25790 is intended for 1-series to 4-series cell li-ion and li-polymer batteries.

The BQ25790 Charger features a narrow VDC architecture (NVDC), which allows the system to be regulated to a minimum value even if the battery is completely discharged.

The TI BQ25790EVM Evaluation Module offers a low battery quiescent current with <5µA at battery-only operation and <1µA in charger shutdown mode. The BQ25790EVM offers a power-up USB port from a battery (USB OTG) with a 2.8V to 22V OTG output voltage with a 10mV resolution.

Features

Synchronous switch mode buck-boost charger for 1s~4s battery configuration and 5A charging with 10mA resolution
Support for 3.6V to 24V wide range of input sources with MPPT, USB auto-detect, USB PD, and wireless input
Dual input source selector to drive bi-directional blocking NFETs
