| sn1086 | |
| general deion the sn1086 is an 11-bit digital temperature sensor with a 2-wire system management bus (smbus) serial interface. the sn1086 accurately measures its own temperature as well as the temperature of an external device, such as processor thermal diode or diode connected transistor such as the 2n3904. the temperature of any asic can be accurately determined using the sn1086 as long as a dedicated diode (semiconductor junction) is available on the target die. the sn1086 remote sensor accuracy of ±1°c is factory trimmed for the 1.008 typical non-ideality factor of the mobile pentium iii thermal diode. the sn1086 has an offset register to allow measuring other diodes without requiring continuous software management.activation of the alert output occurs when any temperature goes outside a preprogrammed window set by the high and low temperature limit registers or exceeds the t_crit temperature limit. activation of the t_crit_a occurs when any temperature exceeds the t_crit programmed limit. applications system thermal management computers office electronics hvac features accurately senses die temperature of remote ics or diode junctions offset register allows sensing a variety of thermal diodes accurately on-board local temperature sensing 10 bit plus sign remote diode temperature data format, 0.125 °c resolution t_crit_a output useful for system shutdown alert output supports smbus 2.0 protocol smbus 2.0 compatible interface, supports timeout 8-pin msop and soic packages key specifications supply voltage 3.0v to 3.6v supply current 0.8ma (typ) local temp accuracy (includes quantization error) ta=25°c to 125°c ±3.0°c (max) remote diode temp accuracy (includes quantization error) ta=30°c to 50°c, td=60°c to 100°c ±1.0°c (max) ta=0°c to 85°c, td=25°c to 125°c ±3.0°c (max)
