SYMBOL
DESCRIPTION
OVD
1
1-Wire Bus Speed Control. Input logic level selects the speed of the 1-
Wire bus. Logic 1 selects overdrive (OVD) and Logic 0 selects standard
timing (STD). On a multidrop bus, all devices must operate at same
speed.
PIO
2
Programmable I/O Pin. Programmed as input or output through internal
registers. Open-drain output sufficient for LED or vibrator activation.
SNS
3
Current-Sense Resistor Input
IS2
4
Current-Sense Input. Connected to SNS through a 10k& resistor to
allow filtering of the current waveform by an external capacitor.
IS1
5
Current-Sense Input. Connected to V
SS
through a 10k& resistor to allow
filtering of the current waveform through an external capacitor.
V
SS
6
Device Ground, Current-Sense Resistor Return. Connect directly to
the negative terminal of the battery cell.
DQ
7
Data I/O Pin. Operates bidirectionally with open-drain output driver.
Internal 1礎(chǔ) pulldown aids in sensing pack removal and Sleep-mode
activation.
V
DD
8
Power-Supply Input. Connects to system voltage supply or positive
terminal of battery cell.
