 CAT823, CAT824, CAT825

Catalyst Semiconductor Inc. has expanded its supervisor product line with the addition of three new devices which provide system processor power supply monitoring and reset functions. The new CAT823, CAT824 and CAT825 voltage supervisors are available in a choice of seven standard threshold levels: 4.63V, 4.38V, 3.08V, 2.93V, 2.63V, 2.32V and 2.19V.

In addition to an active-low reset output included on all three devices, the CAT823 also offers a manual reset and a watchdog input, while the CAT824 provides an additional active-high reset and a watchdog input. The CAT825 features active-low, active-high and manual reset functions.

The CAT823, CAT824 and CAT825 supervisors come in 5-lead TSOT-23 and 5-lead SC-70 packages and are pin-for-pin compatible with MAX823, MAX824 and MAX825 devices. Unlike other vendors, Catalyst offers 2.19V and 2.32V thresholds in both TSOT-23 and SC-70 packages.

The CAT823 features active-low and manual reset and watchdog; CAT824 has active-low and active-high reset and watchdog and CAT825 offers active-low, active-high and manual reset. The three new devices arew pin-for-pin compatible with MAX823, MAX824, MAX825 supervisors and have accurate under-voltage system monitoring.

The CAT823, CAT824 and CAT825 supervisors are priced at 48 cents each in 10,000-piece quantities. Samples of the CAT823 and CAT825 are available while samples of the CAT824 will be available soon. Projected lead-time for production quantities is currently 6 to 8 weeks ARO.
