The BQ24270RGET is a nano-Power Battery charger with integrated power-path and linear controllers from Texas Instruments. It is part of the new series of ultra-low operating current linear PMICs that enable system designers to achieve smarter and more efficient battery charging. This charger is specially designed for battery charging applications for medical, consumer, industrial and automotive products where size and cost are critical factors. It is capable of controlling a variety of input sources, including DC adapter, USB wall charger, USB host ports, powered USB hubs and more, with the lowest possible standby current.

The BQ24270RGET is designed to provide optimal charging performance while also saving power during charging and discharging operations. It utilizes an Adaptive Dynamic Power Management feature that optimizes the power delivered throughout the power path and charger cycle, thereby providing improved efficiency and performance. The Active Series Resistance (ASR) feature is also used to reduce the rechargeable battery self-discharge current, thereby increasing the battery life. Another key feature is its integrated linear controller which allows the system designer to configure the current limits to suit the application’s requirements. In addition, the BQ24270RGET supports both Least Resistance Path (LRP) and Burst Charge Control (BCC) technology.

The BQ24270RGET is an ideal solution for applications which require low current draw and improved battery life. It is designed to operate with an input voltage of 3.2 V to 40 V, and an output voltage of 4.2 V to 12 V. Its maximum output current is 8A, with a minimum current of 250 mA. Its operating temperature range is -40C to +150C, and its operating frequency is 2.5 MHz. Its total standby current consumption is only 2.6 μA. It is small in size, having a package size of 11.2mm x 8.2mm x 1.6mm.

The BQ24270RGET comes with several safety features, including over-voltage protection on the output, under-voltage lockout, over-temperature protection, and reverse current protection. It also provides some additional features, such as a thermistor detector, thermal regulation, an automatic charge termination, an adjustable charge control circuit, and a programmable chip status monitoring capability. The chip includes an 1-Wire interface which allows for remote programming.

The BQ24270RGET is a high-efficiency, energy-saving charger which is designed to help mobile device manufacturers reduce size and cost while providing improved battery life and performance. It is ideal for applications such as wearable devices, handheld devices, mobile phones, tablets, and other mobile and portable devices. Its high power efficiency allows for reduced power consumption, while its low standby current ensures low heat generation during operations. In addition, its safety features make it a safe and reliable device.

By combining advanced energy saving algorithms and control principles, the BQ24270RGET is an ideal platform for quickly and easily designing cost-effective and safe battery charging systems. It can help reduce the size of the product and improve the reliability and performance of the battery. This makes the BQ24270RGET an essential component for any battery-powered application.
