Texas Instruments bq25750 Bi-Directional Buck-Boost Battery Charge Controller is a wide input voltage, Li-polymer, switched-mode buck-boost Li-Ion, or LiFePO 4 battery charge controller with direct power path control. The device offers high-efficiency battery charging over a wide voltage range, charge voltage regulation and accurate charge current, automatic termination, charge preconditioning, and charge status indication. The device integrates all the loop compensation for the buck-boost converter, providing a high-density solution that is easy to use. In reverse mode, the device draws power from the battery and regulates the SYS terminal voltage.
Besides the I2C host-controlled charging mode, the device supports standalone charging mode via resistor programmable limits. Input current, charge voltage regulation, and charge current targets can be set via the ILIM_HIZ, ICHG, and FB pins, respectively. The device has three status pins (STAT1, STAT2, and PG) to indicate the charging and input voltage status. These pins can be used to communicate with a host processor or drive LEDs. If needed, these pins can also be used as general-purpose indicators, and the status is controlled directly by the I2C interface. The INT pin immediately notifies the host when the device status changes, including faults.
The device also provides an analog-to-digital converter (ADC) for monitoring input current, charge current, and input/battery/system/thermistor voltages. The Texas Instruments bq25750 comes with a 36-pin 5.0mm x 6.0mm QFN package with 0.5mm pin pitch.
