The MAX6652AUB+ is a temperature sensor and system monitor in 10 pin μMAX package. This system supervisor monitors multiple power supply voltages, including its own and also features an on-board temperature sensor. Voltage & temperature are converted to an 8bit code using an analogue to digital converter (ADC). A multiplexer automatically sequences through voltage & temperature measurements. Digitized signals are then stored in registers and compared to over/under threshold limits programmed over 2-wire serial interface. 3 interrupt modes are available for temperature excursions, default mode, one-time interrupt mode and comparator mode. IC generates a latched interrupt output ALERT (complementary). The 2-wire serial interface accepts both I2C and standard system management bus (SMBus) write byte, read byte, send byte and receive byte commands to program alarm thresholds and to read voltage and temperature data. It is used in workstations, servers, networking and telecommunicat
Supply voltage range is 2.7V to 5.5V
