October 2003 rev 1.0 ASM811, ASM812 4 Pin µP Voltage Supervisor with Manual Reset Six voltage thresholds are available to support 3V to 5V systems: General Description 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 a preset reset threshold and is asserted for at least 140ms after the supply has risen above the reset threshold. The ASM811 has an active-low output RESET that is guaranteed to be in the www.DataSheet4U.com correct state for VCC down to 1.1V.
