• ACCURACY: ± 1 ° C (typical at +25 ° C)
• PROGRAMMABLE TRIP POINT
The TMP300 is a low-power, resistor-programmable,
digital output temperature switch. It allows a threshold
• PROGRAMMABLE HYSTERESIS: 5 ° C/10 ° C
point to be set by adding an external resistor. Two

levels of hysteresis are available. The TMP300 has a
• LOW-POWER: 110 μ A (max)
V
TEMP
analog output that can be used as a testing
point or in temperature-compensation loops.
• WIDE VOLTAGE RANGE: +1.8V to +18V
• OPERATION: – 40 ° C to +150 ° C
The TMP300 detects temperature with ± 4 ° C accuracy
(max) over – 40 ° C to +125 ° C.
• ANALOG OUT: 10mV/ ° C
With a supply voltage as low as 1.8V and low current
