Temperature switches in SOT packages

Published:2011/8/24 1:17:00 Author:Phyllis

The MAX6509 and MAX6510 made by Maxim are very small temperature switches, which can be configured with a single external resistor to trip at any temperature between -40℃ and + 125℃. The accuracy of the trip point is typically ±0.5℃ and ±4.7℃ maximum. They have a pin that sets the hysteresis to either 2℃ or 10℃. The MAX6509 has an open...   (View)
