BQ24167EVM-720

The BQ24167EVM-720 is a single-chip enhanced buck synchronous battery charger with integrated power path management from Texas Instruments. It is designed for charging 4-cell and 5-cell lithium-ion batteries. The BQ24167EVM-720 combines high-efficiency power conversion and a wide operating range, enabling the charging of battery cells up to 4.5 V. This makes it ideal for applications such as mobile phones, digital cameras, and other portable consumer electronics.

The BQ24167EVM-720 also features programmability, allowing users to customize settings to meet the requirements of the application. It can be configured to charge batteries of different sizes and types using separate charge cycles. Additionally, the BQ24167EVM-720 provides integrated safety features, such as over-temperature protection and cell balancing, to ensure safe and reliable battery charging.

The BQ24167EVM-720 uses a unique buck-like synchronous topology with an integrated power path to enable charging of a battery from a variety of power sources. The synchronous buck topology regulates the voltage applied to the battery, providing current-limited efficient charging for batteries with a low voltage profile. The integrated power path ensures that power is drawn from the external power supply, or the battery, whichever has the highest voltage available. This allows the battery to be safely charged at the correct voltage independent of the power supply.

The BQ24167EVM-720 also has an integrated safety block feature which monitors the voltage and current applied to the battery and limits its charge rate. The safety block limits the total amount of energy delivered to the battery by maintaining a maximum charge current and voltage. This feature ensures that the battery is charged safely and can prevent damage and overcharging.

The BQ24167EVM-720 is a versatile and powerful evaluation and demonstration board suitable for a wide variety of applications. Its wide operating range, programmability, safety features, and integrated power path management make it an ideal choice for lithium-ion battery charging applications. Its synchronous buck topology also ensures efficient and safe charging for batteries of different sizes and types.
