MIC6315
Open-Drain ВµP Reset Circuit General Description Features The MIC6315 is an inexpensive reset generator circuit that
monitors power supplies in microprocessor-based
systems. Precision voltage monitor for 3V, 3.3V, or 5V power
supplies /RESET remains valid with VCC as low as 1V 5ОјA supply current 20ms, 140ms, or 1100ms minimum reset pulse widths
available Manual reset input Available in 4-pin SOT-143 package 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 VCC
has risen above the designed reset threshold level. The
MIC6315 is available in a 4-pin SOT-143 package.
