AMS803/09/10

Features

Description

z Precision supply-voltage monitor

The AMS803/09/10

are microprocessor (µP)

4.63V (AMS803/09/10L)

4.26V (AMS803/09/10M)

3.08V (AMS803/09/10T)

2.93V (AMS803/09/10S)

2.63V (AMS803/09/10R)

2.32V (AMS803/09/10Z)

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 +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.

z 140ms(min) reset pulse width

z Push-Pull /RESET Output Configurations for

AMS809

z Push-Pull RESET Output Configurations for

AMS810

z Open-Drain /RESET output configuration for

AMS803

The AMS803 has an open-drain output stage,

while the AMS809/10 have push-pull outputs. The

AMS803’s open-drain /Reset output requires a pull-up

resistor that can be connected to a voltage higher than

V_CC. The AMS803/09 have an active-low /RESET

output while the AMS810 has an active-high RESET

output. The reset comparator is designed to ignore fast

transients on V_CC, and the outputs are guaranteed to be

in the correct logic state for V_CCdown to 1V.

z 12µA Supply Current

Package

Lead free and Green SOT23-3

Low supply current makes the AMS803/09/10

ideal for use in portable equipment. The ICs are

available in 3 pin SOT23 packages.

Note: “x” refers to voltage range, see below table.
