Texas Instruments\' BQ24073RGTRG4 is an advanced battery charging controller suitable for a variety of applications. It\'s a highly integrated power management integrated circuit (PMIC) that contains integrated synchronous boost converter, switch-mode battery charger, battery temperature protection, and System Power Good detection circuitry.Â

The BQ24073RGTRG4 was developed specifically for charging Li-Ion rechargeable batteries. It features a host of advanced features, such as ultra-low quiescent current, low dropout linear charger, battery temperature protection, and overcharge protection.Â

The BQ24073RGTRG4 is a feature-rich device making it suitable for a wide range of applications, including automotive, portable electronics, wearables, and remote sensing systems. It has excellent performance characteristics whether the device is operating in discontinuous or continuous mode. It includes a number of security features to protect against overcharges and increase system reliability.Â

This device is a highly integrated PMIC device and is classified under PMIC - Battery Chargers. It features a system power good (SPG) pin on the EN line that senses the input voltage and sends a signal to the main power management integrated circuit (PMIC) when the input voltage is within acceptable range. Additionally, the BQ24073RGTRG4 includes over-temperature protection circuitry to protect the device from thermal damage.Â

The device includes integrated synchronous boost converter, N-Channel/P-Channel MOSFETs, and an onboard linear charger that can charge a single-cell lithium-ion/Li-Type battery. The integrated switch-mode charger can be used to charge up to four battery packs simultaneously. It also includes a high conversion efficiency of up to 95%. The BQ24073RGTRG4 also includes advanced safety features to protect the battery from overcharge and over-temperature conditions.Â

The BQ24073RGTRG4 operates in one of two modes, continuous regulation or discontinuous regulation, depending on battery type and application. In continuous regulation, the switch-mode charger is active and maintains a constant voltage at the battery terminals. In discontinuous regulation, the BQ24073RGTRG4 powers off the converter if the charging current falls below the programmed charge current limit. Â

The BQ24073RGTRG4 is built on highly innovative technologies, enabling it to build an efficient, space-saving and cost-effective charging solution. It can be easily integrated with other system components, such as monitoring and control circuits, allowing users to manage the overall system with ease. This PMIC device is suitable for a wide range of applications that require efficient and reliable power management.
