GENERAL DESCRIPTION
The DS2705 provides the master side of a Secure
PIN CONFIGURATION
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.
APPLICATIONS
Digital Cameras
Portable DVD and Media Players
Cradle and Accessory Chargers
Cell Phones/Smartphones
FEATURES
Initiates Challenge-and-Response
Authentication based on the SHA-1 Algorithm
Dallas 1-Wire Master/Slave Interface Operates
at Standard and Overdrive Speeds
Input and Output pins for Initiating Challenge
and Reporting Authentication Pass/Fail
Programmable Configuration
Operates from 2.5V to 5.5V Supply
