| 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. | ||
