DS2703 SHA-1 Battery Pack Authentication IC

HIGH-IMPEDANCE DQ FOR THERMISTOR MEASUREMENT
The user issues a 1-Wire reset followed by a Skip ROMID command, Match ROMID plus the ROMID, Search or
Read Net, followed by the Activate Thermistor command. Within the time period t
TD
the DS2703 disables its DQ
input and internally drives the THM pin low. Immediately following the Activate Thermistor command, the host
system should enable the weak pullup to VCC and then measure the thermistor by sampling the voltage level of
the 1-Wire bus within time t
MIN
. The DS2703 automatically reverts back to communication mode after t
MIN
. See
Figure 12.
