BQ296103DSGT Frequently Asked Questions (FAQs)
Texas Instruments recommends a compact layout with the device placed close to the battery, and the power paths should be short and wide to minimize resistance and inductance. A 4-layer PCB is recommended, with the top layer for signals, the second layer for power, the third layer for ground, and the bottom layer for signals.
The sense resistor value depends on the maximum charge current and the desired accuracy. A lower sense resistor value provides better accuracy but increases power loss. Texas Instruments provides a sense resistor calculator tool to help with the selection.
The EN (enable) pin is used to enable or disable the charger. When EN is high, the charger is enabled, and when EN is low, the charger is disabled. The EN pin can be connected to a GPIO pin of a microcontroller or a power management IC to control the charger's operation.
The BQ296103DSGT has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage divider network. The OVP threshold is set by the voltage divider ratio, and when the input voltage exceeds the threshold, the charger is disabled.
The BQ296103DSGT is rated for operation from -40°C to 85°C. However, the device's performance and reliability may be affected at extreme temperatures. It's essential to ensure proper thermal design and heat dissipation in the application.
