V6319

3-Pin Microprocessor Reset Circuit

Description

Features

The V6309 and V6319 are microprocessor 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 powered or 3V powered circuits.

! Precision monitoring of 3V, 3.3V and 5V power supply

voltages

! Fully specified over the temperature range of

-40 to +125°C

! 140ms minimum power-on reset pulse width:

RESET output for V6309

These circuits perform a single function: they assert a reset

signal whenever the V_DDsupply voltage declines below a

preset threshold, keeping it asserted for at least 140ms after

V_DDhas risen above the reset threshold. The only difference

between the two devices is that the V6309 has an active-low

RESET output (which is guaranteed to be in the correct

state for V_DDdown to 1V), while the V6319 has an active-

high RESET output. The reset comparator is designed to

ignore fast transients on V_DD. Reset thresholds suitable for

operation with a variety of supply voltages are available.

RESET output for V6319

! 16 µA supply current

! Guaranteed RESET/RESET valid to V_DD= 1V

! Power supply transient immunity

! No external components needed

! 3-pin SOT23 package

! Fully compatible with MAX809/MAX810

Applications

! Computer

Low supply current makes the V6309/V6319 ideal for use in

portable equipment. The V6309/V6319 come in a 3-pin

SOT23 package.

! Controllers

! Intelligent instruments

! Critical µP and µC power monitoring

! Portable/battery-powered equipment
