The ASM811/ASM812 are cost effective low power supervisors designed to monitor voltage levels of 3.0V, 3.3V and 5.0V power supplies in low-power microprocessor (µP), microcontroller (µC) and digital systems. They provide excellent reliability by eliminating external components and adjustments. A reset signal is issued if the power supply voltage drops below .
