The MAX1153BEUE+ is a stand alone, 10-channel, 10bit system monitor with internal temperature sensor and VDD monitor in 16 pin TSSOP package. A programmable single-ended/differential mux accepts voltage and remote diode temperature sensor inputs. Device independently monitors input channels without microprocessor interaction and generate an interrupt when any variable exceeds user-defined limits. It configures both high and low limits, as well as the number of fault cycles allowed, before generating an interrupt. ADC can also perform recursive data averaging for noise reduction. At maximum sampling rate of 94Ksps (auto mode, single channel enabled), IC consumes only 5mW (1.7mA at 3V). AutoShutdown reduces supply current to 190µA at 2Ksps and to less than 8µA at 50sps. Stand-alone operation, combined with ease of use in a small package makes ideal for multichannel system-monitoring applications. Low power consumption makes it a good fit for hand-held and battery-powered applications.
