MIC1815 Micrel MIC1815
Microprocessor Reset Circuit General Description Features The MIC1815 is an inexpensive microprocessor supervisory
circuit that monitors power supplies in microprocessor based
systems.
The function of these devices is to assert a reset if the power
supply drops below a designated reset threshold level. Several
different reset threshold levels are available to accommodate
10% or 20% drop in 3.3V powered systems.
The MIC1815 has an active low /RESET output. The reset
output is guaranteed to remain asserted for a minimum of
100ms after VCChas risen above the designated reset threshold level. The MIC1815 comes in a 3-pin SOT-23 package. Precision voltage monitor for 10% or 20% drop in 3.3V
power supplies /RESET remains valid with VCC as low as 1V 5ВµA supply current 100ms minimum reset pulse width No external components required Available in 3-pin SOT-23 package Ordering Information Applications Portable equipment
