Catalyst Semiconductor Inc. has expanded its family of voltage supervisors with four new devices that give designers industry-standard performance for monitoring the power supply status of a microprocessor, microcontroller, ASIC or other system processor.

The CAT853, CAT863, CAT859 and CAT869 extend the company's family of supervisor circuits, providing an even broader range of pin combinations to meet the diverse application requirements of the embedded control market.

The four new new voltage supervisors are available in 3-lead SOT-23 packages. The CAT853 and CAT859 pin configuration is set as: Pin 1: reset; Pin 2: ground; Pin 3: supply voltage. The CAT863 and CAT869 pin configuration is set as: Pin 1: reset; Pin 2: supply voltage; Pin 3: ground.

Catalyst's new microprocessor supervisors are available in standard threshold levels of 2.93V, 3.08V and 4.38V and power supply current of 6?A. The CAT853 and CAT863 feature an open-drain output, active low function. The CAT859 and CAT869 offer a push-pull output, active low function. The devices are pin-for-pin compatible with Microchip, STMicroelectronics and other industry-standard supervisors.

The new voltage supervisors are priced at 24 cents each in 10,000-piece quantities. Samples are available now. Projected lead-time for production quantities is six to eight weeks ARO.
