manufacturer:linear description:the lm89 is an 11-bit digital temperature sensor with a 2-wire system management bus (smbus) serial interface. the lm89 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 lm89 as long as a dedicated diode (semiconductor junction) is available on the target die. the lm89 remote sensor accuracy of 0.75˚c is factory trimmed for the series resistance and 1.0021 typical non-ideality fac- tor of the intel ® pentium™ 4 and the mobile pentium 4 processor-m thermal diode. the lm89 has an offset register to allow measuring other diodes without requiring continuous software management. contact hardware.monitor.team@nsc.com to obtain the latest data for new processors. the lm89 and the lm89-1 have the same functions but different smbus slave addresses. this allows for one of each to be on the bus at the same time. activation of the alert output occurs when any tempera- ture 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. the lm89 is pin and register compatible with the lm86, lm90, analog devices adm1032 and maxim max6657/8. |
