BQ2057WSN Frequently Asked Questions (FAQ)
-
A good PCB layout is crucial for accurate measurements. TI recommends a 4-layer PCB with a solid ground plane, and keeping the sense lines (VSS and VDD) as short as possible. Also, keep the battery voltage and current sense lines away from noisy digital lines.
-
Calibration involves setting the full-scale capacity (FSC) and the empty voltage (EV) registers. FSC is set based on the battery's nominal capacity, and EV is set based on the battery's voltage at 0% SOC. TI provides a calibration procedure in the datasheet and application notes.
-
Temperature affects the BQ2057WSN's accuracy, especially for voltage and current measurements. TI recommends using an external thermistor to measure temperature and applying temperature compensation using the device's built-in temperature compensation registers.
-
The POR and BOR ensure the device resets properly during power-up and brown-out conditions. Designers should ensure that their system can handle the POR and BOR signals, and that the device is properly reset before starting normal operation.
-
The sense resistors (RSENSE) should be chosen based on the maximum expected current, desired accuracy, and power dissipation. TI provides guidelines for selecting RSENSE in the datasheet and application notes.
