MAX6652AUB+

MAX6652AUB+ is a temperature sensor and system monitor. This system supervisor monitors multiple power-supply voltages, including its own, and also features an on-board temperature sensor. Voltages and temperature are converted to an 8-bit code using an analogue-to-digital converter (ADC). A multiplexer automatically sequences through the voltage and temperature measurements. The digitized signals are then stored in registers and compared to the over/under threshold limits programmed over the 2-wire serial interface. When a temperature measurement exceeds the programmed threshold, or when an input voltage falls outside the programmed voltage limits, the MAX6652 generates a latched interrupt output active-low ALERT. Three interrupt modes are available for temperature excursions: default mode, one-time interrupt mode, and comparator mode. It is used in applications such as workstations, servers, networking, telecommunications.
