BQ29706DSET

The BQ29706DSET battery management integrated circuit (IC) is a dedicated device developed to control the charging of single-cell Li-ion and Li-polymer batteries in mobile, wearable, medical, and portable computing applications. The BQ29706DSET is designed with many benefits, which include the ability to accurately track battery voltage, temperature and charge state. It can also monitor the amount of charge and discharge current, and even provide thermal protection for the battery.

The BQ29706DSET is based on a 3-phase switched-mode battery charger architecture that includes a low dropout linear regulator, current sense amplifier and buck converter. This device supports battery charging up to 3A from either a USB connection or an AC adapter. The buck converter integrates a set of high-side and low-side power switches and a compensation network to control the switching frequency. This device also includes an overvoltage protection circuit for the buck output.

The BQ29706DSET features an analog-to-digital converter (ADC) to measure battery voltage, temperature, and charge current to allow a regulated charging cycle. This device also includes a USB-OTG detection circuit and a USB Type-C port, allowing the device to be used with both USB and USB-C compatible charging sources.

The BQ29706DSET has a battery charge protection circuit, which incorporates both over-voltage and over-temperature protection. It also includes a programmable pre-charge and trickle-charge feature, allowing for customized charge profiles to suit the specific application. The BQ29706DSET also includes a power path management feature, which enables the device to be used in USB-only applications, or in AC/DC or USB applications using the ports together, or independently.

The BQ29706DSET has an internal safety timer to ensure that the battery does not remain in an overcharged state for too long. This device also includes an internal clock and oscillator, as well as an internal temperature sensor to ensure proper timing control and monitoring of the battery.

The BQ29706DSET is a versatile battery management integrated circuit, which has a wide range of applications. It is ideal for use in mobile and wearable devices, such as smartphones, smartwatches, and medical devices. It is also useful in portable computing applications, such as tablets and laptops. This device can be used to provide precision control and protection for a single-cell Li-ion or Li-polymer battery, ensuring that the battery is charged quickly and safely.
