Working Principle

The BQ24088DRCR is a synchronous buck converter which uses a buck converter topology for charging Li-Ion and Li-polymer batteries efficiently and safely. It has an integrated high-side power switch and synchronous buck rectification which work together to provide regulated and stable output voltage. The high-side switch provides a voltage boost to the output to ensure the battery is charged at the required voltage level. The synchronous rectification, on the other hand, minimizes losses in the buck converter, enabling it to be highly efficient.

The BQ24088DRCR also has an integrated high-side switch and synchronous rectification which control the charge current and regulation of the output voltage. The high-side switch controls the charging current by adjusting the duty cycle of the switched current. The synchronous rectification provides high voltage efficiency by reducing losses. The combination of these two features ensures that the battery is charged efficiently and safely at the desired voltage level.

The BQ24088DRCR also has an integrated over-temperature protection, over-voltage protection, under-voltage protection and over-current protection. These mechanisms protect the battery from damage by monitoring the battery voltage and temperature and preventing excessive charging currents.
