Description

The ASM809/ASM8091/ASM810 are cost effective 3.0V, 3.3V and 5.0V power supply supervisor circuits optimized for lowpower microprocessor (P), microcontroller (C) and digital systems. They provide a reset output during power-up, powerdown and brown-out conditions. They provide excellent reliability by eliminating external components and adjustments.The ASM809/ASM8091/ASM810 are improved drop-in replacements for the Maxim MAX809/810 and feature 60% lower supply current.

A reset signal of ASM805L 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 ASM809/ASM8091 has an active-low RESET output that is guaranteed to be in the correct logic state for VCC down to 1.1V. The ASM810 has an active-high RESET output. The reset comparator is designed to ignore fast transients on VCC.

Low supply current makes the ASM809/ASM8091/ASM810 ideal for use in portable and battery operated equipment. The ASM809/ASM8091/ASM810 are available in a compact,industry standard 3&5-pin SOT-23 Packages.
