Datasheet AS1910 - AS1915 Dual-Voltage Microprocessor Supervisory Circuits with Manual Reset and Watchdog 1 General Description 2 Key Features The AS1910 - AS1915 microprocessor supervisory circuits were designed to generate a reset when one of the two monitored supply voltages falls below a factory-trimmed threshold, and to maintain the reset for a minimum timeout period when both supplies are above their reset thresholds. Guaranteed to be in the correct state for VCC higher than +1.0V, these devices are ideal for multiple-voltage systems with strict monitoring requirements. The AS1913/AS1914/AS1915 feature factory-trimmed thresholds to monitor a primary voltage between and 3.6V, and a secondary voltage between and 2.5V. For the AS1910/AS1911/AS1912, a secondary monitoring voltage can be user-adjusted via an external resistor divider down to 0.6V.
