描述 Description

LM96080, compatible to LM80, is a hardware monitor that contains a 10-bit delta-sigma ADC capable of measuring 7 positive voltages and local temperature. The LM96080 also measures the speed of two fans and includes other hardware monitoring on an I2C® interface. The LM96080 includes a sequencer that performs WATCHDOG window comparisons of all measured values and its interrupt outputs become active when any values exceed the programmed limits.The LM96080 is especially suited to interface to both linear and digital temperature sensors. The 2.5 mV LSb (least significant bit) and 2.56 volt input range is ideal for accepting inputs from a linear sensor such as the LM94022. The BTI is used as an input from either digital or thermostat sensors such as LM73, LM75, LM56, LM57, LM26, LM27, LM26LV, or other LM96080. The LM96080 supports Standard Mode (Sm, 100 kbits/s) and Fast Mode (Fm, 400 kbits/s) I2C interface modes of operation. LM96080 includes an analog filter on the I2C digital control lines that allows improved noise immunity and supports TIMEOUT reset function on SDA and SCL that prevents I2C bus lockup. Three I2C device address pins allow up to 8 parts on a single bus.The LM96080's 3.0V to 5.5V supply voltage range, low supply current, and I2C interface make it ideal for a wide range of applications. Operation is ensured over the temperature range of (−40)°C ≤ TA ≤ +125°C. The LM96080 is available in a 24-pin TSSOP package.
