Power Management Integrated Circuits (PMICs) are devices used in computers, and other digital devices, to manage the power needed. one of the types within the power management category is the battery management part of it, which helps to manage the power for battery-powered devices. The BQ24350DSGR is a battery management integrated circuit specifically designed for portable and embedded applications.

The BQ24350DSGR application field pertains to a number of battery-dedicated applications, such as energy harvesting systems, embedded system development, battery-powered medical and industrial products, portable medical and home-networking products, and wearable electronics. This integrated circuit has great capabilities to allow up to three fully-integrated buck and/or boost charge gates. It also can provide simultaneous, regulated 5V, 3.3V, and 1.5V outputs with a low quiescent current that gives efficiency and excellent system performance.

The BQ24350DSGR works by providing a two-phase, current-mode charge controller architecture that can produce up to four regulated outputs. It features low battery detection and measurement accuracy of ±1% over-temperature . This integrated circuit comes with configurable power modes and all necessary monitoring features for the fault protection of the battery cells. This is accomplished by Built-In Excessive Charge Current Protection Timer (ECCPT) for safety charging and discharge. In addition, the BQ24350DSGR also features an integrated over-voltage protection (OVP), short circuit protection (SCP) and incorporated over-temperature (OT) protection. These features contribute to the battery management performance of the device.

The BQ24350DSGR also provides fast charge switching and programmable charging current limit up to 1.5A. This allows the BQ24350DSG to achieve a faster charging time with a small form factor due to the integrated FETs. Furthermore, this integrated circuit also has the capability to detect low-battery disconnect, while providing a charge current limit preset to 1.5A.

Overall, the BQ24350DSGR is a comprehensive and highly integrated device that can provide high efficiency and excellent system performance with low quiescent current. Additionally, the device features a two-phase, current-mode charge controller architecture that can provide up to four regulated outputs with fast charging. The integrated FETs and its associated safety features, including over-voltage protection, short circuit protection and over-temperature protection allow for robust protection of the battery cells. These features give the BQ24350DSGR a competitive edge in the field of battery management.
