Evaluation Board for ISL9237
Manufactured By:INTERSIL
Part Number:ISL9237EVAL2Z
The ISL9237EVAL2Z evaluation board is designed to demonstrate the performance of the ISL9237. The default value numbers of the battery in series, the switching frequency, and the adapter current limit charging function can be programmed by the resistor from the PROG pin to GND. Those values also can be set by SMBus.
The ISL9237 is a buck-boost Narrow Output Voltage DC (NVDC) charger utilizing Intersil’s advanced R3™ Technology to provide high light-load efficiency, fast transient response, and seamless DCM/CCM transitions for a variety of mobile and industrial applications. In Charge mode, the ISL9237 takes input power from a wide range (4V to 20V) of DC power sources (conventional AC/DC charger adapters, USB PD ports, travel adapters, etc.) and safely charges battery packs with up to three cells in a series configuration. The ISL9237 supports On-the-Go (OTG) function for 2- and 3-cell battery applications. When OTG function is enabled, the ISL9237 operates in Reverse Buck mode to provide 5V at the USB port. The ISL9237 has serial communication via SMBus/I2C that allows programming of many critical parameters to deliver a customized solution. These programming parameters include, but are not limited to: adapter current limit, charger current limit, system voltage setting, and trickle-charging current limit.
