Voltage supervisor reduces operating current and board space 'significantly'
1 min read
ON Semiconductor has announced a voltage supervisor which it claims is much smaller and more space efficient than many existing devices.
The CAT8710 is designed for applications such as gaming consoles, set top boxes, communications and industrial control equipment.
The device is suitable for simultaneously monitoring multiple voltages in microprocessor or asic based systems, and can be operated from a supply voltage of 1.5 to 5.5V. It draws 3µA and according to On Semi consumes10% of the power required for similar products.
Four voltage level monitors are integrated into a single six-pin, SOT-23 package, which the company says allows the CAT8710 to occupy approximately 25% board space compared to four individually packaged devices.
Two factory preset thresholds monitor 3.3, 3.0, 2.5 and 1.8V supplies within +/-5%, along with two that are customer programmable using external resistors and adjustable down to 0.6V.
On Semi's product marketing manager, Configurable Analogue Products, Thruston Awalt, said: "Space and power efficiency are the two most important considerations in the latest generation product designs. The CAT8710 quad-voltage supervisor excels in these two areas while also giving design engineers a high degree of flexibility with both preset and programmable monitors."
