SPECIAL FEATURE REGISTER
The format of the special feature register is shown in Figure 7. The function of each bit is described in
detail in the following paragraphs.

OT
PSF—
PS Flag. This bit is reset to 0 when the DS2720 detects the PS pin is pulled to V
SS
. This bit does
not set itself to a 1 after the PS pin returns to a high logic level, and thus must be set by the host system
to detect future events. This bit is initialized to a 1 upon POR.
OT
—Overtemperature Flag. When set to 1, this bit indicates the battery pack has experienced an
overtemperature condition. This bit does not clear itself after the overtemperature state is corrected, and
thus must be reset by the host system after the temperature decreases below T
MAX
to re-enable the charge
and discharge FETs. Writing a 1 to this bit disables the FETs, but this is not recommended. The OT bit is
a volatile R/W bit, initialized to 0 upon POR.
X
—Reserved Bits.
PS
INPUT PIN
The PS pin is internally pulled to V
DD
through a high-value resistance. PS is continuously monitored for
a low-impedance connection to V
SS
. Connecting PS to V
SS
wakes up the DS2720 if it was in sleep mode.
If the DS2720 was in active mode, PS has no effect.
1-WIRE BUS SYSTEM
The 1-Wire bus is a system that has a single bus master and one or more slaves. A multidrop bus is a 1-
Wire bus with multiple slaves. A single-drop bus has only one slave device. In all instances, the DS2720
is a slave device. The bus master is typically a microprocessor in the host system. The discussion of this
bus system consists of four topics: 64-bit net address, hardware configuration, transaction sequence, and
1-Wire signaling.
64-BIT NET ADDRESS
Each DS2720 has a unique, factory-programmed 1-Wire net address that is 64 bits in length. The first
eight bits are the 1-Wire family code (31h for DS2720). The next 48 bits are a unique serial number. The
last eight bits are a CRC of the first 56 bits (see Figure 8). The 64-bit net address and the 1-Wire I/O
circuitry built into the device enable the DS2720 to communicate through the 1-Wire protocol detailed in
the
1-Wire Bus System
section of this data sheet.
