PIN DESCRIPTION
PIN
NAME
FUNCTION
1
V
DD
Supply Voltage. 2.7V to 5.5V
2
TO
Active-High Thermostat Output. Open-drain output transitions from low to high when the output
voltage exceeds V
TH
. In shutdown mode, (SD = 1), TO is low.
3
TO
Active-Low Thermostat Output. Open-drain output transitions from high to low when the output
voltage exceeds V
TH
. In shutdown mode, (SD = 1), TO is high.
4
V
OUT
Temperature Output. Outputs a voltage that is proportional to the die temperature in degrees
centigrade. In shutdown mode, this pin goes high-Z.
5
V
TH
Thermostat Trip Voltage. User-selectable voltage that sets the thermostat trip-point temperature.
TO and TO are asserted when V
OUT
crosses this voltage. (No on-chip hysteresis is present).
6
SD
Shutdown. Power consumption and thermal sensor function are controlled through SD. This pin
functions as an active-high input pin. Driving this pin high puts the device in a low-power state and
discontinues thermal sensing.
7
CTG
Must be connected to GND.
8
GND
Ground.
PAD
PAD. Connect to GND or float. DO NOT CONNECT TO SUPPLY. The exposed pad is the best
way to conduct temperature into the package. Connecting PAD to a ground plane can assist in
properly measuring the temperature of the circuit board.

TEMPERATURE MEASUREMENT
The DS600 analog temperature sensor measures it own temperature and provides these measurements to the
user in the form of an output voltage, V
OUT
, that is proportional to degrees centigrade. The output voltage
characteristic is factory-calibrated for a typical output gain (擵/擳) of +6.45mV/癈 and a DC offset (V
OS
) of 509mV.
Its operating temperature range is -40癈 to +125癈, corresponding to an output voltage range of 251mV to
1315mV. (V
OUT
= Device Temperature (癈) x 擵/擳 + V
OS
). The DS600 has ?.5癈 accuracy over a -20癈 to
+100癈 temperature range and over the full 2.7V to 5.5V voltage range. Because the output voltage is positive for
the entire temperature range, there is no need for a negative supply.
Figure 2 shows the output voltage characteristic for the DS600.
