BQ 24753A

The BQ24753A is a highly integrated, single-chip battery charger IC from Texas Instruments. It is designed to charge lithium-ion and lithium-polymer batteries in portable devices such as smartphones, tablets, and laptops.

The BQ24753A features a number of advanced features, including:

• Dynamic Power Management (DPM) to optimize battery charging current based on the available input power
• Input power limiting to avoid overloading the AC adapter when supplying the load and the battery charger simultaneously
• Highly-accurate current-sense amplifier to enable precise measurement of input current
• 6-V gate drives for better system efficiency
• Inrush-power limiting for instantaneous response to high input voltage multiplied by current
• AC Overpower protection (ACOP) to limit the input-switch power to the programmed level on the ACOP pin

The BQ24753A is a popular choice for battery charger ICs in portable devices because of its high integration, advanced features, and small size.

Here are some of the benefits of using the BQ24753A:

• Reduced power consumption: The BQ24753A’s DPM feature helps to reduce power consumption by optimizing the battery charging current based on the available input power. This can extend the battery life of portable devices.
• Improved system efficiency: The BQ24753A’s 6-V gate drives help to improve system efficiency by reducing the power loss associated with switching external switches.
• Increased safety: The BQ24753A’s inrush-power limiting and ACOP features help to improve system safety by protecting the AC adapter and the device from damage due to high input voltage or current.

Overall, the BQ24753A is a highly integrated, feature-rich battery charger IC that is well-suited for use in portable devices.
