MAX1755 - SOT23 Local Temperature Comparators

General Description

The MAX1755/MAX1756 are temperature monitors with ±3°C accuracy, each with a built-in comparator 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.

19-1852; Rev 1; 3/01 SOT23 Local Temperature Comparators with SMBus Serial Interface General Description The MAX1755/MAX1756 are temperature monitors with ±3°C accuracy, each with a built-in comparator 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.
