The BQ2003S-NTRG4 is a powerful smart battery charger, also known as PMIC – Battery Chargers. It is specifically designed to meet the battery-charging requirements of smart portable equipment, such as mobile phones, PDAs and other similar devices. The BQ2003S-NTRG4 offers all necessary features to provide the most efficient and safe battery-charging process.

The BQ2003S-NTRG4 features an input voltage range of 4.5V to 24V and is capable of delivering up to 3A of current to a single cell Li-ion or Li-Polymer type battery. It also features power switch and charge status output pins, allowing efficient monitoring of the battery-charging process. Additionally, the BQ2003S-NTRG4 provides accuracy in charge current and voltage thresholds to ensure the most reliable and safest battery-charging experience.

The BQ2003S-NTRG4 includes over-current protection, thermal protection, over-voltage protection, and short-circuit protection in order to provide the highest level of safety and performance of the charging process. It also provides a buffered battery-detect comparator, which can be used to detect the insertion of a battery, indicator LED’s for charge status, and an option for two-wire serial interface for system configuration.

The BQ2003S-NTRG4 operates on the principle of dual-mode charging. In the Constant-Current mode, the current is maintained at a predetermined value until the battery voltage reaches the voltage threshold. Once it reaches this voltage, the charger will transition to Constant-Voltage mode. The final voltage is then maintained until the charging current falls below a predetermined level when the charger will enter the Standby mode.

The BQ2003S-NTRG4 is an ideal choice for a wide variety of applications, including portable electronics such as mobile phones, PDAs and other similar battery-powered devices. Being fully certified and UL/IEC60950 approved also means that it meets the highest safety and performance standards for these applications.

In summary, the BQ2003S-NTRG4 PMIC – Battery Chargers offer a great advantage for those with battery-powered applications, offering powerful and reliable charging performance, accurate and safe charging thresholds, and a strong level of protection against current and voltage fluctuations. Furthermore, it is a fully certified and UL/IEC60950 approved product, providing the highest quality charging experience available.
