Low-Cost, +2.7V to +5.5V, Micropower

Temperature Switches in SOT23 and TO-220

________________General Description

____________________________Features

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 +115°C in 10°C increments, and are accurate to

0.5°C ꢀtypꢁ or 6°C ꢀmaꢂꢁ. These devices reꢃuire no

eꢂternal components and typically consume 30µA sup-

ply current. Hysteresis is pin-selectable at +2°C or

+10°C.

ꢀ SOT23-5 and TO220-7 Packages

The MAX6501/MAX6503 have an active-low, open-drain

output intended to interface with a microprocessor ꢀµPꢁ

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 +115°Cꢁ, assert-

ing when the temperature is above the threshold. The

MAX6503/MAX6504 are offered with cold-temperature

thresholds ꢀ-45°C to +15°Cꢁ, 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 5-pin SOT23 and 7-pin TO-220

packages.

Typical Operating Circuit

*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

SOT23-5 package with a +65°C threshold. Contact the factory for

pricing and availability of nonstandard temperature versions (mini-

mum order 10,000 pieces).
