MIC6315
General Description
The MIC6315 is an inexpensive reset generator circuit that
monitors power supplies in microprocessor based sys-
tems.
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
minimum of either 20ms, 140ms, or 1100ms after V CC has
risen above the designed reset threshold level. The MIC6315
comes in a 4-pin SOT-143 package.
