Description
B15:B8
Reserved for future use; can not be written; should be ignored; will read as 0
B7 (Note 17)
0: Configuration Register bit 4 is frozen upon Configuration Register bit 8 being set
(i.e. a TS shut−down freezes the EVENT output)
1: Configuration Register bit 4 is cleared upon Configuration Register bit 8 being set
(i.e. a TS shut−down de−asserts the EVENT output)
B6
0: Not used
1: The TS implements SMBus time−out within the range 25 to 35 ms
B5
B4:B3
0: Not used
1: Defined for compatibility with CAT34TS02 device (V_HV is supported)
00: LSB = 0.50°C (9 bit resolution)
01: LSB = 0.25°C (10 bit)
10: LSB = 0.125°C (11 bit)
11: LSB = 0.0625°C (12 bit)
B2
0: Not used
1: The temperature monitor can read temperatures below 0°C and sets the sign bit appropriately
B1
0: Not used
1: The temperature monitor has ±1°C accuracy over the active range (75°C to 95°C) and ±2°C
accuracy over the monitoring range (40°C to 125°C)
B0
0: Not used
1: The device supports interrupt capabilities
17. Configuration Register bit 4 can be cleared (but not set) after Configuration Register bit 8 is set, by writing a “1” to Configuration Register
bit 5 (EVENT output can be de−asserted during TS shut−down periods)
