ASM1834/A/D

Dual 5V and 3.3V µP Power Supply Supervisor with Manual Reset

All devices operate over the extended industrial temperature

range. Devices are available in 8-pin DIP, surface mount 8-pin

SO and 8-Pin MicroSO packages. Die are also available.

General Description

The ASM1834 supervisors simultaneously monitor both 3.3V

and 5V power sources and generate reset signals when either

supply is out of tolerance. When an out-of-tolerance condition is

detected, the output-reset signal of the affected supply

becomes active and resets the system microprocessor/

microcontroller. On power-up and after the supply voltage

returns to an in-tolerance condition, the reset signal remains

active for approximately 350ms. This allows the power supply

and system microprocessor to stabilize.

Key Features

•

Monitors 5V and 3.3V supplies simultaneously

5V and 3.3V power-on reset

350ms reset time

Debounced pushbutton reset input

Push-pull CMOS output

• ASM1834, ASM1834D

• Eliminates external pull-up resistors

• Active LOW (ASM1834), HIGH (ASM1834D)

Open Drain Output

Tolerance levels are independently selectable for both supplies.

Tolerance options are 5% and 10% percent for the 5V supply

and 10% and 20% percent for the 3.3V supply.

•

• ASM1834A

• Active LOW

The ASM1834 and ASM1834D have push-pull reset output

stages. The ASM1834A reset outputs are open drain devices

that can both be connected to either 5V or 3.3V supply. The

ASM1834 and ASM1834A have active LOW reset outputs. The

ASM1834D has active HIGH reset outputs.

•

Selectable 5V and 3.3V trip point tolerance

Internal power drawn from highest input voltage, 5V or

3.3V

Precision temperature-compensated voltage reference and

comparator

Low cost surface mount SO, compact MicroSO and DIP

packages.

Wide operating temperature, -40°C to +85°C

•

All devices can generate reset signals through an internally

debounced pushbutton reset input that affects both reset

outputs.
