AIC Offers AIC809/810/811/812 Supervisory ICs
Analog Integration Corp. (AIC, Hsinchu, Taiwan) launched a new series of microprocessor supervisory ICs, the AIC809, AIC810, AIC811 and AIC812, which are low-power microprocessor supervisory circuits used to monitor power supplies in microprocessor and digital systems. They provide circuit reliability and low cost by eliminating the need for external components.
The devices perform as valid signals in applications with Vcc ranging from 6.0 V down to 0.9 V. The reset signal lasts for a minimum period of 140 ms whenever the Vcc supply voltage falls below the preset threshold. All the devices were designed with a reset comparator to identify invalid signals, which lasts less than 140 ms. A low supply current of 1 mA makes the AIC809/AIC810/AIC811/AIC812 suitable for monitoring the voltage of portable devices such as notebook computers, digital still cameras, PDAs, and other critical microprocessor applications. The series are available in the SOT-23 package.
The AIC809/AIC810/AIC811/AIC812 Series provides several internally fixed threshold voltages to choose from (2.3 V, 2.6 V, 2.9 V, 3.1 V, 4.0 V, 4.4 V and 4.6 V). The difference between the AIC809/810 and the AIC811/812 is that the AIC811/812 offers a manual-reset input pin.
