Ultra-Low Current Consumption and High-Accuracy Voltage Detection
Reset IC with Built-In Delay Circuit
PST87/88xx Series
Announced on October 2, 2009
Overview
In recent years the popularity of cell phones and mobile music players has increased demand for components of reduced size and lower power consumption. Moreover,the drop in the driving voltage of personal computers has led to requirements for higher-accuracy voltages.
At Mitsumi we have always devoted resources to expanding our lineup of compact devices with low current consumption for power monitoring of computer peripherals, and we have now developed the < PST87/88xx series >, which retains the compact package and high-accuracy of previous models while adding new functionality with a built-in delay circuit.
