14 | ----------- | |
15 | ||
16 | The LM77 implements one temperature sensor. The temperature | |
17 | sensor incorporates a band-gap type temperature sensor, | |
18 | 10-bit ADC, and a digital comparator with user-programmable upper | |
19 | and lower limit values. | |
20 | ||
21 | Limits can be set through the Overtemperature Shutdown register and | |
22 | Hysteresis register. |
