Temperature monitor for microprocessor systems
11. Characteristics
[1] The value of V
DD
below which the internal A/D converter is disabled. This is designed to be a minimum of 200 mV above the power-on
reset. During the time that it is disabled, the temperature that is in the read temperature registers will remain at the value that it was
before the ADC was disabled. This is done to eliminate the possibility of reading unexpected false temperatures due to the A/D
converter not working correctly due to low voltage. In case of power-up (rising V
DD
), the reading that is stored in the read temperature
registers will be the default value of 0 癈. As soon as V
DD
has risen to the value of UVLO, the ADC will function correctly and normal
temperatures will be read.
[2] V
DD
(rising edge) voltage below which the ADC is disabled.
[3] V
DD
(falling edge) voltage below which the logic is reset.
[4] Address is read at power-up and at start of conversion for all conversions except the fastest rate.
[5] Due to the bias current, any pull-up/pull-down resistors should be ?2 kW.
