TOLERANCE AND ACCURACY
The primary function of the voltage supervisor is to keep the
processor in a reset state whenever the processor supply voltage is
below the specification limit. It needs to be able to differentiate
the voltage out-of-processor limit from supply variations caused by
voltage converter output tolerance. This means that the supervisor
rest threshold should fit inside the narrow band between processor
input tolerance and supply tolerance.
The ADM8710 offers up to ±2% accuracy on factory trimmed
monitoring thresholds and ±1.5% accuracy on adjustable
thresholds over the entire operating temperature range.
