Frequently Asked Questions
What is the maximum charge current and target voltage of the BQ24200DGNG4 linear charger IC?
The BQ24200DGNG4 provides a maximum charge current of 500 mA and regulates to a 4.1 V charge termination voltage, making it suitable for single-cell Li-Ion and Li-Polymer batteries. Its linear architecture simplifies the charging circuit by eliminating the need for an external inductor, reducing BOM cost for low-power portable designs.
How does the BQ24200DGNG4's optional temperature monitoring feature protect battery packs in wearable applications?
The BQ24200DGNG4 includes an optional NTC thermistor input that monitors battery temperature before and during charging. If the temperature falls outside the safe charging window (typically 0°C to 45°C for Li-Ion), the IC suspends charging, preventing thermal damage and extending battery cycle life. This feature is valuable in wearables and compact devices where heat dissipation is limited.
What package does the BQ24200DGNG4 use, and how does the exposed pad help in a USB-powered charger design?
The BQ24200DGNG4 is housed in an 8-pin HVSSOP (equivalent to TSSOP-8 with 0.19" body) package featuring an exposed thermal pad. In a USB-powered 500 mA linear charger, the IC dissipates up to several hundred milliwatts as heat; the exposed pad transfers this heat directly to the PCB copper pour, keeping junction temperature within safe limits without an external heatsink.
