The function of this device is to assert a reset if either the

power supply drops below a designated reset threshold

level or /MR is forced low. Several different reset threshold

levels are available to accommodate 3V, 3.3V or 5V powered

systems.

The MIC6315 has an active low, open-drain /RESET output.

The reset output is guaranteed to remain asserted for a
