Texas Instruments bq25792EVM/bq25798EVM Charger Evaluation Modules

Texas Instruments bq25792EVM/bq25798EVM Charger Evaluation Modules (EVMs) are used to evaluate the bq25792 or bq25798 device. The bq25792/bq25798 devices are integrated switched-mode buck-boost battery charge management devices in HOTROD (QFN) package. They are intended for 1-series to 4-series cell Li-ion and Li-polymer batteries from 3.6V to 24V input with programmable 750KHz and 1500KHz switching frequency. The I2C serial interface with charging and system settings makes the device a truly flexible solution. The Texas Instruments bq25798 has a maximum power point tracking (MPPT) feature for use with HiZ power sources like solar panels.

Features

  • Easily evaluate the high-efficiency 5A switch-mode buck-boost charger in the HOTROD (QFN) package
  • For the bq25792EVM, the use of EV2400 interface to switch between charge and USB On-the-Go (OTG) as well as monitor charger status and faults as well as voltages and current with an integrated analog-to-digital converter (ADC)
  • For the bq25798EVM, the use of EV2400 or USB2ANY interface to switch between charge and USB On-the-Go (OTG) as well as monitor charger status and faults as well as voltages and current with an integrated analog-to-digital converter (ADC)
  • Use of an onboard USB input adapter for connecting to a USB source and either communication through D+/D– to set the default input current limit
  • Onboard test points, sense resistors, and jumpers facilitate measurement of high-efficiency and high-accuracy voltage and current-regulation
  • Bi-directional blocking NFETs included for evaluating dual input source selector, with jumpers to bypass

Kit Contents

  • bq25798EVM evaluation module
  • Kit does not include the EV2400 or USB2ANY, which is required for operation
