ON Semiconductor's New Subminiature Package For Voltage Detector Series Promotes Space-Saving Designs

Share

Phoenix, Arizona - August 27, 1999 - Designers can provide voltage continuity for microcontroller systems in about half the space previously used by designing with a new series of voltage detectors introduced by ON Semiconductor, today. Housed in a new subminiature package, the units can be placed anywhere and provide optimal space saving advantages in applications such as laptop computers.

The miniature 4-lead SC-70 (SC-82AB) package measures only 2.0mm x 2.1mm x 0.9mm (length x width x thickness) and is approximately half the size of a SOT-23 package. ON Semiconductor offers two new detectors in the new package, types MC33460 and MC33461, that were designed for use in small, portable, wireless communication applications, where the miniature SC-70 package space saving is very appealing to designers.

These new voltage detectors send a RESET to a MPU/MCU whenever the supply voltage falls below an internally preset threshold. No external components are required, which reduces the overall system cost and complexity while increasing the system reliability. They also have a very wide operating voltage ranging from 0.7V to 10V and feature an ultra low supply current of 0.8 mA typical. The +/- 2% accuracy of the built-in hysteresis ensures stable switching.

The MC33460 features an active low, open-drain RESET output, whereas the MC33461 features an active low, push-pull RESET output. These devices are now available with internally preset thresholds of 0.9V, 2.0V, 2.7V, 2.8V, 3.0V, 3.2V, 4.3V, and 4.5V. Other voltage options can be provided in steps of 0.1V increments.

The MC33460/MC33461 are housed in the new 4-lead SC-70 (SC-82AB) surface mount package. Samples and production quantities are immediately available and are priced at $0.35 each in quantities of 15K units.
