Sot23 Local Temperature Comparators With Smbus Serial Interface

The MAX1755 MAX1756 are temperature monitors with 3C accuracy, each with a built-in Comparator and SMBus-controlled variable trip threshold. This DAC- programmable 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 out- put (ALERT). A variety of slave addresses allow for up to six devices per system (Table 3). The MAX1755 has 4C of built-in hysteresis. The MAX1756 detects both low-to-high and high-to-low tem- perature transitions within an 8C temperature window. This arrangement supports windowing algorithms where the comparison threshold is reprogrammed on- the-fly. The MAX1755 MAX1756 are offered in the 6-pin SOT23 package and are specified over the -40C to +125C temperature range.
