Catalyst Semiconductor, Inc. (NASDAQ:CATS) a supplier of analog, mixed-signal and non-volatile memory semiconductors, continues the rapid expansion of 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.
- CAT823: active-low and manual reset; watchdog
- CAT824: active-low and active-high reset; watchdog
- CAT825: active-low, active-high and manual reset
- Pin-for-pin compatible with MAX823, MAX824, MAX825 supervisors
- 7 Reset thresholds: 4.63V, 4.38V, 3.08V, 2.93V, 2.63V, 2.32V and 2.19V
- Accurate under-voltage system monitoring
- Packaging: 5-lead TSOT-23 and 5-lead SC-70
Price and Availability
The CAT823, CAT824 and CAT825 supervisors are priced at $0.48 each in 10,000 piece quantities. Samples of the CAT823 and CAT825 are available now; samples of the CAT824 will be available soon. Projected lead-time for production quantities is currently 6 to 8 weeks ARO.
