1.8V, Resistor-Programmable  
TEMPERATURE SWITCH and  
ANALOG OUT TEMPERATURE SENSOR in SC70

FEATURES  
DESCRIPTION  
2
ACCURACY: ±1°C (typical at +25°C)  
PROGRAMMABLE TRIP POINT  
PROGRAMMABLE HYSTERESIS: 5°C/10°C  
OPEN-DRAIN OUTPUTS  
The TMP300 is a low-power, resistor-programmable,  
digital output temperature switch. It allows a threshold  
point to be set by adding an external resistor. Two  
levels of hysteresis are available. The TMP300 has a  
VTEMP analog output that can be used as a testing  
point or in temperature-compensation loops.  
LOW-POWER: 110μA (max)  
WIDE VOLTAGE RANGE: +1.8V to +18V  
OPERATION: –40°C to +150°C  
ANALOG OUT: 10mV/°C  
The TMP300 detects temperature with ±4°C accuracy  
(max) over –40°C to +125°C.  
With a supply voltage as low as 1.8V and low current  
consumption, the TMP300 is ideal for power-sensitive  
systems.
