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.

Selector Guide and Pin Configurations appear at end of

data sheet.

Note: 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.

Contact the factory for pricing and availability of nonstandard

temperature versions (minimum order 10,000 pieces).
