FlexiHash For Battery Authentication

ISL6296A

The ISL6296A is a highly cost-effective fixed-secret hash engine based on Intersil’s FlexiHash technology. The device’s authentication is achieved through a challenge response scheme, which is customized for low-cost applications where cloning via eavesdropping without knowledge of the device’s secret code is not economically viable. When used for its intended applications, the ISL6296A offers the same level of effectiveness as other significantly more expensive high maintenance monetary-grade hash algorithm and authentication schemes.

The ISL6296A has a wide operating voltage range and is suitable for direct powering from a 1-cell Li-ion/Li-Poly or a 3-cell series NiMH battery pack. The ISL6296A can also be powered by the XSD bus when the bus pull-up voltage is 3.3V or higher. The device connects directly to the cell terminals of a battery pack and includes on-chip voltage regulation circuit, POR and a noncrystal based oscillator for bus timing reference.
