HWD810 - 3-Pin Microprocessor Reset Circuits

Download the HWD810 datasheet PDF. This datasheet also covers the HWD803 variant, as both devices belong to the same 3-pin microprocessor reset circuits family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.

3-Pin Microprocessor Reset Circuits General 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. These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The HWD803 has an open-drain output stage, while the HWD809/HWD810 have push-pull outputs.
