MAX1755
Description
The MAX1755/MAX1756 are temperature monitors with ±3°C accuracy, each with a built-in parator and SMBus™-controlled variable trip threshold. This DACprogrammable threshold allows specific thermal zones and system responses to overtemperature conditions to be adjusted under software control. The MAX1755/ MAX1756 feature serial programmability, low cost, wide supply-voltage range, and a tiny package. The MAX1755 has a self-clearing thermostat output (OVERT), and the MAX1756 has a latched interrupt output (ALERT). A variety of slave addresses allow for up to six devices per system (Table 3). The MAX1755 has 4°C of built-in hysteresis. The MAX1756 detects both low-to-high and high-to-low temperature transitions within an 8°C temperature window. This arrangement supports “windowing” algorithms where the parison threshold is reprogrammed “onthe-fly.” The MAX1755/MAX1756 are offered in the 6-pin SOT23 package and are specified over the -40°C to +125°C temperature range.
