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 1.8 and 3.6V, and a secondary voltage between 0.9 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. The devices are available with the following reset output types:
The AS1910 - AS1915 include a manual-reset input for systems that never fully power down the microprocessor. Additionally, these devices feature a watchdog timer to help ensure that the processor is operating within proper code boundaries.
The AS1910 - AS1915 are available in a 6-pin SOT23 package.
