BQ25700ARSNT

Power management IC (PMICs) play a crucial role in the operation of a variety of electronic devices, as they efficiently manage the output of a system’s power source. Among them is the Texas Instruments BQ25700ARSNT, a USB Type-C and USB PD controller that provides embedded system designers with a complete and configurable power path solution for the battery, system load and VBUS.

The BQ25700ARSNT is a USB Type-C and USB PD controller that is specifically designed for battery-powered applications. It is capable of charging and discharging both Li-ion and Li-polymer batteries, and also provides balanced and unbalanced charging capability for a variety of battery configurations. The integrated power electronics includes a buck-boost VBUS regulator, an LDO, and USB PD current limited switches for the VBUS and GND lines. The device also provides power path control for selecting any combination of the battery, system load, and VBUS as the power source.

The BQ25700ARSNT has a maximum battery charging current of 1.5A and is capable of fast charging using proprietary charge algorithms. It also supports “Power Delivery” profile negotiation and USB PD communication to ensure compatibility with a variety of portable devices. The “Hibernate” feature of the device provides a low-power state for battery-based applications and greatly reduces system power consumption without interruption to system operation.

When it comes to system control, the BQ25700ARSNT is capable of managing system power routing, system LED control and user button interactions. An integrated “Phoenix Mode” enables charging and powering the system even in the absence of battery or wall power. The BQ25700ARSNT also supports the “Vu-Meter” function that shows information about the system battery status, charging status and system voltage.

The BQ25700ARSNT is an ideal choice for any embedded or portable device requiring an efficient and configurable power path solution. Its integrated features and configurable designs make it easy to manage the output of the system’s power source, while providing a robust and reliable solution. This makes the BQ25700ARSNT an excellent choice for any battery-powered application.
