Power management integrated circuits (PMICs) are a vital and integral component to any device that requires efficient storage and delivery of electrical power. PMICs play a key role in modern battery-powered and hybrid electric vehicles, but they can also be used in a variety of other applications, ranging from consumer electronics, to industrial applications (such as robotics), to automotive and aviation applications. Broadly speaking, PMICs can be divided into two categories: Battery Management ICs and Power Management ICs.

BQ24351DSGR is a battery management integrated circuit (BMIC) designed to improve system performance, efficiency, and safety in applications that require high voltage power sources such as portable medical and industrial equipment, battery-operated consumer electronics, and automotive and aerospace systems.

The BQ24351DSGR offers designers a wide range of features and benefits that are designed to make it easier to manage high voltage batteries. Some of the features of the BQ24351DSGR include charge current share, low battery detection and disconnect, overvoltage protection, short circuit protection, and reverse protection.

The charge current share feature ensures that each cell in the battery pack is charged at a safe and equal rate. This is important in applications where the pack has multiple cells in parallel. The low battery disconnect feature prevents the battery from discharging excessively, which can cause damage to the device or the battery itself. The overvoltage protection feature ensures that the battery is not overcharged, which reduces the risk of battery failure due to thermal runaway. The short circuit protection feature protects against external short circuits, while the reverse protection feature protects against reversed polarity connections.

The BQ24351DSGR works by continuously monitoring the voltage of the battery and charging the battery accordingly. When the voltage drops below a predetermined threshold, the device begins charging the battery until it reaches its full charge capacity. Once the battery is fully charged, the device will reduce the charging current to maintain the battery at its full capacity. If the battery begins discharging, the device will resume charging the battery until the voltage drops below a certain threshold.

The BQ24351DSGR is an efficient, cost-effective solution for managing high voltage batteries. It can provide charging, monitoring, and safety features that are essential for reliable operation of battery-powered systems. Its features and benefits make it an ideal choice for a wide range of applications.
