ILC809

Impala Linear Corporation ILC803/ILC809/ILC810 Preliminary 3-Pin µP Voltage Monitor General Description The ILC803, ILC809 and ILC810 are low cost microprocessor supervisory circuits that assert a reset if the power supply drops below a designated threshold. Several different reset thresholds are available to accommodate systems operating at 3V, 3.3V or 5V. The ILC803 has an open drain output stage with active low RESET output The ILC809 has an active low RESET output, while the ILC810 offers an active high RESET output. The reset output is guaranteed to remain asserted for a minimum of 140ms after VCC has risen above the designated reset threshold. The ILC803, ILC809 and ILC810 are available in either a 3-Pin SOT-23 package or a 3-Pin SC-70 packages. Package Features Precision Voltage Monitor for 3V, 3.3V or 5V Power Supplies 6µA Supply Current 140ms Minimum Reset Pulse Width RESET Remains Valid with VCC as Low as 1.4V Active Low Manual Reset Input No Exter...
