________________General Description
The MAX6501–MAX6504 low-cost, fully integrated tem-
perature switches assert a logic signal when their die
temperature crosses a factory-programmed threshold.
Operating from a +2.7V to +5.5V supply, these devices
feature two on-chip, temperature-dependent voltage
references and a comparator. They are available with
factory-trimmed temperature trip thresholds from -45°C
to +125°C in 10°C increments, and are accurate to
±0.5°C (typ) or ±6°C (max). These devices require no
external components and typically consume 30µA sup-
ply current. Hysteresis is pin-selectable at 2°C or 10°C.
The MAX6501/MAX6503 have an active-low, open-drain
output intended to interface with a microprocessor (µP)
reset input. The MAX6502/MAX6504 have an active-
high, push-pull output intended to directly drive fan-
control logic. The MAX6501/MAX6502 are offered with
hot-temperature thresholds (+35°C to +125°C), assert-
ing when the temperature is above the threshold. The
MAX6503/MAX6504 are offered with cold-temperature
thresholds (-45°C to +15°C), asserting when the tem-
perature is below the threshold.
The MAX6501–MAX6504 are offered in eight standard
temperature versions; contact the factory for pricing
and availability of nonstandard temperature versions.
They are available in a 5-pin SOT23 package.

These parts are offered in eight standard temperature
versions with a minimum order of 2,500 pieces. To complete
the suffix information, add P or N for positive or negative trip
temperature, and select an available trip point in degrees
centigrade. For example, the MAX6501UKP065+T describes a
MAX6501 in a SOT23 package with a +65°C threshold.
