Catalyst Semiconductor Expands Supervisor Family with Three New Industry-Standard Devices

(Product News, 17 Sep 2007)

Catalyst Semiconductor Inc. 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.
