Keywords:Catalyst Semiconductor  open-drain  output devices  voltage supervisors  CAT803 

Catalyst Semiconductor Inc. has added two open-drain output devices to its line of industry-standard voltage supervisors. The CAT803 voltage supervisor and CAT808 voltage detector provide an open-drain output, active low function. The CAT803 has a reset timeout, with 140ms guaranteed reset period while the CAT808 has no reset timeout.

The CAT803 is available in standard threshold levels ranging from 2.32V to 4.63V and is the drop-in replacement for MAX803. Whereas, the CAT808 is available in 2.7V and 3.2V threshold levels and is pin-for-pin compatible with S-808 voltage detector.

The power supply current for CAT803 extends to 6µA and for CAT808 extends to 2.4µA

Pricing for 10,000 piece quantities of the CAT803 and the CAT808 is (20 cents) each. Samples are now available. Projected lead-times for production quantities are currently six to eight weeks ARO.
