DETAILED PIN DESCRIPTION Table 2
PIN
SYMBOL
DESCRIPTION
1
DQ
Data Input/Output pin for 3-wire communication port.
2
CLK/ CONV
Clock input pin for 3-wire communication port. When the DS1620 is used in a
standalone application with no 3–wire port, this pin can be used as a convert pin.
Temperature conversion will begin on the falling edge of CONV.
3
NC
No internal connection
4
RST
Reset input pin for 3-wire communication port.
5
GND
Ground pin
6
RA
Connection to one side of internal 50 ohm resistor
7
NC
No internal connection
8
NC
No internal connection
9
NC
No internal connection
10
NC
No internal connection
11
RB
Connection to one side of internal 50 ohm resistor
12
TCOM
High/Low Combination Trigger. Goes high when temperature exceeds TH;
will reset to low when temperature falls below TL.
13
TLOW
Low Temperature Trigger. Goes high when temperature falls below TL.
14
NC
No internal connection
15
THIGH
High Temperature Trigger. Goes high when temperature exceeds TH.
16
VDD
Supply Voltage. 5V input power pin.
OPERATION – THERMOSTAT CONTROLS
Three thermally triggered outputs, THIGH, TLOW , and TCOM , are provided to allow the DS1620R to be used
as a thermostat, as shown in Figure 2. When the DS1620R’s temperature meets or exceeds the value
stored in the high temperature trip register, the output THIGH becomes active (high) and remains active
until the DS1620R’s measured temperature becomes less than the stored value in the high temperature
register, TH. The THIGH output can be used to indicate that a high temperature tolerance boundary has
been met or exceeded, or it can be used as part of a closed loop system to activate a cooling system and
deactivate it when the system temperature returns to tolerance.
