Voltage Supervisors with More Pin Configuration Options
Catalyst Semiconductor has added to its range of voltage supervisors with four new devices that give designers industry-standard performance for monitoring the power supply (Vcc) status of a microprocessor, microcontroller, ASIC or other system processor.
The All four of Catalyst’s 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. 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, STMicro and other industry-standard supervisors.
The CAT853, CAT863, CAT859 and CAT869 voltage supervisors are priced at $0.24 each in 10,000 piece quantities. Samples are available now. Projected lead-time for production quantities is currently 6 to 8 weeks ARO.
