General Description

The MAX6513 is a fully integrated, remote temperature

switch that uses an external P-N junction (typically a

diode-connected transistor) as the sensing element to

measure the remote temperature. The device asserts a

logic signal when the temperature crosses a factory-

programmed threshold. Available trip thresholds are

from +45癈 to +125癈 in 10癈 increments. Accuracy is

within ?癈 (T

= -5癈 to +55癈) or ?癈 (T

= -40癈

to +85癈). Hysteresis is pin selectable to 5癈 or 10癈.

The MAX6513 has an active-high CMOS output. The

output is asserted when the temperature exceeds the

threshold value. The active-high CMOS output can

directly drive a power FET to control a cooling fan.

The MAX6513 operates from a +3.0V to +5.5V supply

and typically consumes 400礎 of supply current. It is

available in a 6-pin lead-free TDFN package.
