General Description

The MIC6315 is an inexpensive reset generator circuit

that monitors power supplies in microprocessor-based

systems.

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 remains asserted for a

minimum of either 20 ms, 140 ms, or 1100 ms after

VCC has risen above the designed reset threshold

level. The MIC6315 is available in a 4-pin SOT-143

package.
