Working Principle

The MAX16922ATPE/V+ is a power management device with a high efficiency switching voltage regulator and digital charging. It is designed for use with a range of battery chemistries, including lead-acid, lithium ion and other battery chemistries. The device controls the charging current and voltage of the battery, as well as the discharge current from the battery. It also protects the battery from reverse current.

The main components of the device include: the main regulator, the battery current monitor, the charge controller, the voltage comparator and the low-battery disconnect. The main regulator is responsible for converting the AC input voltage from the battery to a regulated DC voltage level. The battery current monitor measures the current flowing through the battery and signals the charge controller to stop charging if the current exceeds a certain limit. The charge controller then controls the charging rate based on the current and voltage readings.

The voltage comparator takes the battery voltage as input and compares it to a reference voltage. It then signals the low-battery disconnect to shut off the system if the battery voltage is too low. This protects the battery from deep-discharge or over-discharge. Finally, the reverse current protection prevents the energy from flowing in the opposite direction and damaging the battery.

The MAX16922ATPE/V+ is an advanced power management device specifically designed for applications requiring main and backup battery solutions. Its high efficiency switching voltage regulator, digital charging, low-battery disconnect, and reverse current protection make it ideally suited for industrial, automotive and consumer applications.
