The ISL95520AHRZ is a dual channel, 3-cell battery charger, which is designed for automatic charging of 2S/3S Li-Ion/Li-Polymer batteries. The device operates with dual P-channel MOSFETs enabled by the input voltage conditioning stage, and includes an accurate current limit protection and negative discharge MOSFET enable. In addition, it also includes an internal voltage regulator and an analog reference voltage, enabling an accurate voltage regulation with Digital Compensator. The device supports trickle charging, -dV/dt, 0V reset sensing and automatic cell balancing.

The working principle of the ISL95520AHRZ involves three steps. Firstly, the input power is conditioned and regulated. This is done by two separate P-channel MOSFETs connected to the VIN voltage and GND terminals, and the current is limited by a sense resistor connected in between them. Then, the current limitation along with other functions, such as a 0V reset, or a -dV/dt, is adjusted and regulated by a digital compensator. Finally, the charge current and the pre-determined voltage are regulated and measured accurately, by connecting the sense resistor to the testing terminal.

The ISL95520AHRZ’s primary application is in portable or home electronic products, such as tablet computers. It can also be used in applications, such as industrial automation, robots, power tools, automotive accessories, and medical devices. The device is ideal for applications with a low input voltage, and is highly reliable and cost-effective, making it an excellent choice for many applications.
