Texas Instruments bq2573xEVM Controller Evaluation Module (EVM)

Texas Instruments bq2573xEVM Controller Evaluation Module (EVM) are for the evaluation of the bq2573x devices. The bq2573x is an I²C controlled NVDC (narrow voltage DC) buck-boost charge controller with an N-channel MOSFET selector and current monitoring. The input voltage range for the buck converter is between 3.5V and 26V, with a programmable output of 1 to 5 cells and a charge output current range of 128mA to 15A. These evaluation modules do not include the EV2400 interface device. The interface device will have to be ordered separately to evaluate the Texas Instruments bq2573xEVM.

Features

Host-controlled NVDC 1S to 5S battery buck-boost charger with 3.5V to 26V input; 1V to 23V charging output, and 3V to 24V OTG output
Supports USB 2.0, USB 3.0, USB 3.1 ( USB Type-C™) and USB_PD platforms
Supports 5mΩ current sense for high current, high efficiency

Support 400kHz or 800kHz switching frequency for high efficiency
Patented switching frequency dithering pattern for meeting IEC-CISPR 32 EMI specification
Flexible power path or non-power path option

Required Equipment
