Typical SPI One-Shot Write to Configuration Register Followed by a Read from the Temperature Value Register TEMPERATURE 149°C 148°C 147°C 146°C 145°C 144°C 143°C 142°C 141°C 140°C CT PIN POLARITY = ACTIVE LOW CT PIN POLARITY = ACTIVE HIGH TCRIT TCRIT – THYST TIME *THERE IS A 240ms DELAY BETWEEN WRITING TO THE CONFIGURATION REGISTER TO START A STANDARD ONE-SHOT CONVERSION AND THE CT PIN GOING ACTIVE. THIS IS DUE TO THE CONVERSION TIME. THE DELAY IS 60ms IN THE CASE OF A ONE-SHOT CONVERSION.

One-Shot CT Pin ONE-SHOT MODE When one-shot mode is enabled, the ADT7320 immediately completes a conversion and then goes into shutdown mode. The one-shot mode is useful when one of the circuit design priorities is to reduce power consumption. To enable one-shot mode, set Bits [6:5] of the configuration register (Register Address 0x01) to 01. After writing to the operation mode bits, wait for at least 240 ms before reading back the temperature from the temperature value register. This delay ensures that the ADT7320 has adequate time to power up and complete a conversion. To obtain an updated temperature conversion, reset Bits[6:5] of the configuration register (Register Address 0x01) to 01. CT and INT Operation in One-Shot Mode See Figure 13 for more information on one-shot CT pin operation for TCRIT overtemperature events when one of the limits is exceeded. Note that in interrupt mode, a read from any register resets the INT and CT pins. For the INT pin in comparator mode, if the temperature drops below the THIGH − THYST value or goes above the TLOW + THYST value, a write to the operation mode bits (Bit 5 and Bit 6 of the configuration register, Register Address 0x01) resets the INT pin. For the CT pin in comparator mode, if the temperature drops below the TCRIT − THYST value, a write to the operation mode bits (Bit 5 and Bit 6 of the configuration register, Register Address 0x01) resets the CT pin (see Figure 13). When using one-shot mode, ensure that the refresh rate is appropriate to the application being used. |
