GENERAL DESCRIPTION
The DS2703 provides a robust cryptographic solution
to ensure the authenticity of Li-Ion battery packs for
cell phone, PDA, and portable computing devices.
The DS2703 employs the Secure Hash Algorithm
(SHA-1) specified in the Federal Information
publication 180-1 and 180-2, and ISO/IEC 10118-3.
SHA-1 is designed for authentication
required for identifying battery packs manufactured
by authorized sources.
The device’s SHA-1 engine processes a host
transmitted challenge using its stored 64-bit secret
key and unique 64-bit ROM ID to produce a 160-bit
response word for transmission back to the host. The
secret key is securely stored on-chip and never
transmitted between the battery and the host. A
DS2703-based system produces a high degree of
authentication security between a host system and its
removable battery or other peripheral devices.
The Thermistor Multiplexer feature allows a three
contact battery pack configuration to support data
and thermistor functions. When activated through
1-Wire command, the THM pin presents the
thermistor impedance on the data contact and
disconnects internal loading from the node.
