... There are three selectable logic address pins so that eight devices can be connected on the same bus without address conflict. The SE95 can be configured for different operation conditions. It can be set in normal mode to periodically monitor the ambient temperature shutdown mode to minimize power consumption. ...

... Watchdog FUNCTIONAL DESCRIPTION General operation The SE95 uses the on-chip band-gap sensor to measure the device temperature with the resolution of 0.03125 C and stores the 13-bit 2’s complement digital data, resulted from 13-bit A-to-D conversion, into the device Temp register. This Temp register can be read at any ...

... N/A 2004 Dec 21 Register list The SE95 contains 7 data registers. The registers can be 1 byte or 2 bytes wide, and are defined in Table 2. The registers are accessed by the value in the content of the pointer register during I communication. The types of registers are: read only, read/write, ...

... Obviously, for 9-bit Temp data application in replacing the industry standard LM75, just use only 9 MSB bits of the two bytes and disregard 7 LSB bits of the LS byte. The 9-bit temp data with 0.5 C resolution of the SE95 is defined exactly in the same way as for the standard LM75 and it is here similar to the Tos and Thyst that is described next ...

... If the OS output is in comparator mode, then it remains unchanged. In Interrupt mode, the OS output is reset. Power-up default and Power-on Reset The SE95 always powers-up in its default state with: – Normal operation mode – OS comparator mode – Tos = 80 C – Thyst = 75 C – ...
