Key Features

3-Pin Microcontroller

◆

Improved Maxim MAX809/MAX810 replacement

— Lower supply current…6µA

— 80% lower maximum supply current

Power Supply Supervisor

The IMP809/IMP810 are 3.0V, 3.3V and 5.0V power supply supervisor cir-

cuits optimized for low-power microprocessor (µP), microcontroller (µC)

and digital systems. The IMP809/810 are improved drop-in replacements

for the Maxim MAX809/810 and feature 60% lower supply current.

◆

Monitor 5V, 3.3V and 3V supplies

140ms min. reset pulse width

Active-low reset valid with 1.1V supply

(IMP809)

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 IMP809 has an active-low RESET

output that is guaranteed to be in the correct state for V_CCdown to 1.1V.

The IMP810 has an active-high RESET output. The reset comparator is

◆

Small 3-pin SOT-23 package

No external components

Specified over full temperature range

— –40°C to 105°C

designed to ignore fast transients on V_CC

Low supply current makes the IMP809/IMP810 ideal for use in portable

and battery operated equipment. The IMP809/IMP810 are available in a

compact 3-pin SOT23 package.

Applications

Six voltage thresholds are available to support 3V to 5V systems:
