MAX6332 and MAX6333

Vishay Semiconductor

3 Pin, Low-Power, µP Reset Circuits

Pin Configuration

SOT-23 (Top View)

Description

• The MAX6333 and 6332 are system supervisor

circuits designed to monitor V in digital systems

GND

and provide a reset signal to the host processor

when necessary. No external components are

required.

• When the processor power supply voltage drops

below the reset threshold, the reset output is driven

Reset

active, in less than 40µs (T ). Reset is main-

tained active for a time period (T ), after the V

rises above the threshold voltage.

• To prevent jitter, the reset threshold voltage has a

built-in hysteresis of 0.4% of V

Fig. 1 – Typical Application Diagram

• The MAX6333 has an active-low reset output,

while the MAX6332 has an active-high reset

output. Both devices have push/pull output drives.

• The reset signal is guaranteed valid, down to

= 1.0V.

µP

• Low supply current of 3µA makes these devices

well suited for battery powered applications. They

are designed to reject fast transients from causing

false resets.

SOT-23 package.

Features

Applications

• Tight reset voltage tolerances ± 1.8%

• Computers

• Low supply current: <3µA

• Critical µP/µC power monitoring

• Battery powered equipment

• Automotive electronics

• Precision monitoring of 1.8V and 2.5V

powersupply voltages

• Other threshold voltage options available from

1.5V to 2.5V in approximately 100mV increments

• Three reset active time-out period options:

typical 1.5mS, 30mS, 150mS

• Reset output guaranteed down to 1.0V

• V transient immunity

• No external components
