NAME FUNCTION
1 -— -— WARN
Open-Drain Active-Low Warning Output. WARN goes low
when the die temperature exceeds T
WARN = T ALARM -
∆T
AW.
-— 1 -— -— WARN
Push-Pull Active-High Warning Output. WARN goes high
when the die temperature exceeds T
WARN = T ALARM -
∆T
AW.
2 2 2 2 GND Ground
3, 5 3, 5 -— -— S1, S0
Delta Temperature Select Input. Connect to V CC or GND to
select the difference between T ALARM and T WARN (Table
1 or see Electrical Characteristics).
-— -— 3 3 S0
Hysteresis Select Input. Connect to V CC for 10 °C
hysteresis. Connect to GND for 2 °C hysteresis.
4 4 4 4 V CC
Supply Voltage Input. Bypass V CC to GND with a 0.1 µF
ceramic capacitor.
-— -— 5 5 N.C. No Connection. Not internally connected.
-— -— 6 -— OVER
Open-Drain Active-Low Overtemperature Output. OVER
goes low when the die temperature exceeds the factory-
set value of T
OVER .
-— -— _ 6 OVER
Push-Pull Active-High Overtemperature Output. OVER
goes high when the die temperature exceeds the factory-
set value of T
OVER.
-— -— 1 -— OK
Open-Drain Active-High Temperature Sensor Output. OK
goes high impedance when the die temperature is
between the factory-set values of T
OVER and T UNDER .
When the die temperature is above T OVER or below
T UNDER , OK goes low.
-— -— -—
1
OK
Push-Pull Active-Low Temperature Sensor Output. OK
goes low when the die temperature is between the factory-
set values of T
OVER and T UNDER . When the die temp-
erature is above T OVER or below T UNDER , OK goes high.
6 -— -— -— ALARM
Open-Drain Active-Low Alarm Output. ALARM goes low
when the die temperature exceeds the factory-set value of
T
ALARM .
-— 6 -— -— ALARM
Push-Pull Active-High Alarm Output. ALARM goes high
when the die temperature exceeds the factory-set value of
T
ALARM .
