GENERAL DESCRIPTION
The TC6501 through TC6504 are SOT-23 temperature
switches that require no external components and the
design is facilitated with factory programmed temperature
thresholds. A choice of factory-trimmed temperature trip
points are available. Pin selectable hysteresis of +2C or
+10C allows flexibility to the design. These parts typically
consume only 17
A of current and operate over the entire
–55C to +125C temperature range while offering accura-
cies of
±0.5C (typ) and ±4C (max).
The TC6501 and TC6503 offer an open drain, active low
output, meant for microprocessor reset control. The TC6502
and TC6504 have a CMOS, active high output designed to
drive a logic level MOSFET to turn on a fan or heater element.
The TC6501/TC6502 are aimed for hot-temperature
monitoring (+35
°C to +115°C). These devices assert a logic
signal when the temperature goes above the threshhold.
The TC6503/TC6504 are aimed for cold-temperature moni-
toring (-45
°C to +15°C). These devices assert a logic signal
when the temperature goes below the threshhold.
The TC6501 through TC6504 are offered in five stan-
dard temperature thresholds. Available in 5-Pin SOT-23A
packages, these parts are ideal for applications requiring
high integration, small size, low power and low installed
cost.

Notes: TC6501 and TC6502 are offered in 3 standard temperature settings. Other non-standard versions are
available (including 55
°C, 75°C, 85°C,
105
°C and 115°C), please contact factory for more information. TC6503 and TC6504 are offered in 2 standard temperature settings. Other non-
standard versions are available (including -45
°C, -35°C, -25°C and -5°C), please contact factory for more information.
A letter “P” in the part number indicates a positive temperature sign or “N” for a negative temperature sign.
