ISL6251HRZ is a pulse-width modulation (PWM) integrated circuit, specially designed for efficient battery charging. It is an ideal choice for applications, such as battery-powered hand-held devices, such as mobile phones, digital cameras, MP3 players and tablets. It can be used in a wide variety of applications, including portable power, automotive, renewable energy and medical applications.

The ISL6251HRZ contains all the components required for a complete, еfficient and convenient battery charging system. It contains two PWM controllers which can be used in parallel to effectively control the charging voltage of the battery and3 two-stage battery protection thresholds. These two thresholds prevent overcharging and over-discharging of the battery. The maximum charging current can be set and adjusted through the output of the PWM controller.

The integrated circuit also contains several other additions, such as a low voltage disconnect (LVD) circuit, charge current frequency selection, thermal protection, over-voltage and high-temperature shutdown, as well as an external temperature sensor for improved safety. The LVD circuit ensures that the battery does not discharge below a predefined voltage and thus keeps the battery in a safe operating range.

The ISL6251HRZ also features an active power factor correction (PFC) circuit which provides a constant current to the battery even when the input voltage varies. This facilitates the battery charging process and allows for better efficiency. The integrated circuit also includes a Power Good (PG) output which monitors the charge status of the battery.

The ISL6251HRZ is a highly versatile and efficient device that is used in many applications. It is designed to easily accept input voltages from as low as 8V up to as high as 14V and is capable of providing an output current of up to 4A. The integrated circuit is designed to be very energy-efficient and is capable of providing an efficiency of up to 95%.

The ISL6251HRZ is an ideal choice for applications that require an efficient and reliable battery chargers. It is capable of safely charging a variety of battery types, such as Li-Ion, Li-Polymer, Ni-MH, and Lead-Acid. It has a wide operating temperature range from -40°C to +85°C, which makes it a suitable choice for use in extreme environmental conditions. The ISL6251HRZ is also a very cost-effective solution for many battery charging applications.
