D2, D4, E3 Power-Supply Terminal. The DS1852 will support supply voltages
ranging from +2.7V to +5.5V.
GND B3, C2, C4, D3 Ground Terminal
SDA B5 2-Wire Serial Data. The serial data pin is for serial data transfer to and
from the DS1852. The pin is open drain and may be wire-OR’ed with
other open-drain or open-collector interfaces.
SCL A5 2-Wire Serial Clock. The serial clock input is used to clock data into
the DS1852 on rising edges and clock data out on falling edges.
B
in
A3 Analog Input Pin (Bias Value). Input to A/D.
P
in
D1 Analog Input Pin (Lower Level). Input to A/D.
R
in
A2 Analog Input Pin (Received Power). Input to A/D.
ASEL B2 Address Select Pin. If set to logic 0, the device address is A0h. If set to
logic 1, the value in Table 3, byte D0h determines the chip address
(factory default is A2h). For SFF-8472 compliance, this pin should be
connected high.
D
in
C5 Digital Input Pin (TX Disable). Digital input for mirroring in memory
map.
RS
in
B4 Digital Input Pin (Rate Select). Digital input for mirroring in memory
map.
F
in
E5 Digital Input Pin (TX Fault). Digital input for mirroring in memory
map.
L
in
A1 Digital Input Pin (LOS). Digital input for mirroring in memory map.
