Supervisory Circuits Tout Low Power Dissipation

Six microprocessor supervisory circuits--the IMP1810, IMP1811, IMP1812, IMP1815, IMP1816 and IMP1817--have been added to the firm's Power Management line. The devices are lower power, direct replacements for devices originally offered by Dallas Semiconductor, with supply current requirements reduced by as much as 57% compared to the original parts. Maximum supply current is as low as 15 µA and typical supply current is 8 µA. The chips are designed to stop and restart a microcontroller or microprocessor when a power supply is out of spec or is being powered on or off. Typical applications include wireless communication devices, PDAs, vending machines, home appliances and automation systems, GPS receivers, industrial control systems, and set-top boxes.
