EMC1202 Summary of contents
Page 1
... The EMC1201 and EMC1202 are temperature sensors that communicate with a host over a single-wire SMSC BudgetBus™ Sensor Interface. The EMC1201 has an internal temperature sensor and the EMC1202 adds one remote diode. Packaged in a SOT23-5, the EMC1201 provides an accurate, low-cost, low-current, solution for critical temperature monitoring in applications such as embedded systems or computers ...

... The host initiates active mode by enabling a weak pull up on the BBUS. In this mode, the EMC1201 and EMC1202 continuously convert temperature data. During the time that the device is actively converting a temperature, the BBUS is in tri-state mode, and the Host places a weak pull-up on the bus to prevent it from floating ...
