The BQ29700DSE is a TinyFuel Secondary Side Protection device developed by Texas Instruments. It is a robust solution for managing the current flow in secondary battery systems. This device provides protection against over-discharge and short-circuit, as well as the ability to regulate voltage in multi-cell battery packs. This device is ideal for applications such as consumer and industrial electronics, medical devices, and green transportation.

The BQ29700DSE is an integrated device with all necessary protection circuitry built in. It has a built-in comparator and a shut-down reset circuit with active-low reset output. The device also features host voltage output, which is used to monitor system voltage. Additionally, the device has an internal temperature sensor that helps detect various system conditions and protect the battery from over-temperature.

The device works by monitoring the battery voltage and current. When the system voltage exceeds a certain preset voltage, the device shuts down the system to protect the battery. Additionally, the device can be configured to monitor and limit the system current. This helps to protect the battery from over-current or short-circuit conditions and prevent damage.

In addition to these protection features, the BQ29700DSE provides a range of system control functions. These include under-voltage and over-voltage protection for cell monitoring, as well as power-on reset and inhibit functions. The device also provides a range of sleep mode settings, allowing the system to enter low-power states in order to reduce power consumption.

The BQ29700DSE is a compact and reliable solution for managing the current flow in secondary battery systems. It provides a range of protection and control features, making it ideal for use in various applications. This device can help reduce risk of damage to the battery, ensuring optimal system performance and reliability.
