BQ24055DSSR is a type of power management integrated circuit, or PMIC for short. It is widely used for battery charging applications. It comes with features such as programmable charging current and voltage, integrated protection against over-voltage, over-current, and under-voltage.

BQ24055DSSR is part of Texas Instrument\'s single-cell battery chargers. It is specifically designed for lithium-ion batteries and other battery chemistries. It is an ideal solution for applications such as cellular phones, digital cameras, personal media players, and other portable devices that require efficient power management.

At the heart of the BQ24055DSSR is its programmable current- and voltage-sensing devices. The devices allow users to specify the exact charging current and voltage at start-up. With its integrated power-distribution devices, the BQ24055DSSR can provide up to 5A of charging current. The integrated power-distribution devices also feature adjustable voltage clamps for over-voltage and under-voltage protection.

The BQ24055DSSR also has a built-in boost converter, which can provide up to 8V at 200mA. This is useful for applications that require a higher voltage. The BQ24055DSSR has an input voltage range of 5-26V and a voltage switch-off threshold of 6.5V, allowing for fast and efficient power delivery.

The BQ24055DSSR also has an integrated boost control feature, which is designed to prevent the battery from overcharging. When the battery is fully charged, the boost control feature will reduce the charging current to a safe level, ensuring long-term battery life. The BQ24055DSSR also has a power-saving mode, which allows it to conserve power when the battery is not in use.

In addition to the main features mentioned above, the BQ24055DSSR also features a host-portable I/O interface for quick and easy communication with other system components. The BQ24055DSSR supports various communication protocols, including I2C, SMBus, UART, and SPI. It also has internal protection mechanisms to protect against short circuits and over-currents.

The BQ24055DSSR is an ideal solution for battery charging applications. Its programmable current- and voltage-sensing devices make it easy to configure the charging parameters, while its integrated protection mechanisms and boost control feature ensure long-term battery life. With its host-portable I/O interface, the BQ24055DSSR is designed to make system integration fast and easy.
