BQ707-BQ24707

The BQ707 is a single-cell Li+ battery SMBus charge controller from Texas Instruments. It is a simplified version of the BQ717, with fewer features but also a lower price.

The BQ707 features a number of key features, including:

• Integrated power MOSFETs for charging and discharging the battery
• SMBus interface for configuration and monitoring
• Programmable charging current and voltage
• Constant current (CC) charging algorithm
• Battery safety features such as overcharge protection, overdischarge protection, and short-circuit protection

The BQ707 is a good choice for battery charge controllers in portable devices where cost is a major factor. It offers a basic set of features that are essential for safe and reliable battery charging.

Here are some of the benefits of using the BQ707:

• Affordable: The BQ707 is one of the most affordable battery charge controller solutions on the market.
• Easy to use: The BQ707 is easy to use with its SMBus interface. This allows for easy configuration and monitoring of the charger.
• Safe: The BQ707’s safety features help to protect the device and battery from damage due to overcharging, overdischarging, or short-circuit.

Overall, the BQ707 is a basic but reliable battery charge controller that is well-suited for use in cost-sensitive portable devices.

BQ707 vs BQ717

The BQ707 and BQ717 are very similar, but the BQ717 has a few additional features:

• It supports a wider range of input and battery voltages.
• It has a higher programmable charging current.
• It has a lower power consumption.
• It supports multiple charging algorithms, including constant current (CC) and constant voltage (CV).

In general, the BQ717 is a better choice for applications where performance is a priority, such as smartphones and tablets. The BQ707 is a better choice for cost-sensitive applications, such as wearable devices and low-power IoT devices.
