TMP300
SBOS335D –JUNE 2005–REVISED JANUARY 2016
TMP300 1.8V, Resistor-Programmable Temperature Switch and
Analog Out Temperature Sensor in SC70
1 Features 3 Description
The TMP300 is a low-power, resistor-programmable,
1
• Accuracy: ±1°C (Typical at +25°C)
digital output temperature switch. The device allows a
• Programmable Trip Point
threshold point to be set by adding an external
• Programmable Hysteresis: 5°C/10°C
resistor. Two levels of hysteresis are available. The
TMP300 has a V
TEMP
analog output that can be used
• Open-Drain Outputs
as a testing point or in temperature-compensation
• Low Power: 110μA (Max)
loops.
• Wide Voltage Range: +1.8V to +18V
With a supply voltage as low as 1.8V and low current
• Temperature Range: –40°C to +125°C
consumption, the TMP300 is ideal for power-sensitive
• Analog Out: 10mV/°C
systems.
• SC70-6 and SOT23-6 Packages
Available in two micropackages that have proven
thermal characteristics, this part gives a complete and
