Product details

Description

The HWD803/HWD809/HWD810 are microprocessor (µP) supervisory circuits used to monitor the power supplies in µP and digital systems.

They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V, or +2.5V powered circuits.

Features

o Precision Monitoring of +2.5V, +3V, +3.3V, and +5V Power-Supply Voltages o Fully Specified Over Temperature o Available in Three Output Configurations Open-Drain RESET Output (HWD803) Push-Pull RESET Output (HWD809) Push-Pull RESET Output (HWD810) o 140ms min Power-On Reset Pulse Width o 12µA Supply Current o Guaranteed Reset Valid to VCC = +1V o Power Supply Transient Immunity o No External Components o 3-Pin SC70 and SOT23 Packages Ordering Information PART TEMP. RANGE PIN-.
