GENERAL DESCRIPTION
The DS2705 provides the master side of a Secure
Hash Algorithm (SHA) based token authentication
scheme. Hardware-based SHA authentication allows
for security without the added cost and complexity of
a microprocessor-based system. Batteries and other
accessories are authenticated using a single contact
through the Dallas 1-Wire interface. Authentication
is performed on demand or automatically, with the
pass/fail status reported on open-drain output pins to
signal the charge system and/or drive LEDs. The
DS2705 stores a predetermined challenge-and-
response pair in nonvolatile (NV) EEPROM. The
DS2705 works in conjunction with Dallas Battery
Management SHA-1 token products, including the
DS2703 and DS2704.
