Austriamicrosystems introduces its AS1925 and AS1926 single ultra-low voltage microprocessor supervisory ICs that are designed to monitor supply rails of 0.9 to 1.5 V in µP and digital systems without the need for external components, forcing a reset if the monitored supply voltage drops below its reset threshold. A variety of factory-trimmed voltage thresholds from 0.81 to 1.425 V are available for monitoring 0.9 V, 1.2 V and 1.5 V supplies with 5 % or 10 % tolerances. The preset voltages can be monitored without external components. The AS1925 features both a push-pull active-high and active-low reset output. The AS1926 offers a push-pull active-high and an open-drain active-low reset output.
