LTC2932

Conﬁgurable Six Supply

Monitor with Adjustable Reset

Timer and Supply Tolerance

DESCRIPTION

FEATURES

The LTC^®2932 is a conﬁgurable supply monitor for sys-

tems with up to six supply voltages. One of 16 preset or

adjustable voltage monitor combinations can be selected

using an external resistive divider connected to the mode

select pin. The preset voltage thresholds are digitally

conﬁgurable to 5%, 7.5%, 10%, or 12.5% below the

nominal operating voltage. The LTC2932 also features

adjustable inputs with a 0.5V nominal threshold. All six

open-drain voltage comparator outputs are connected to

separate pins for individual supply monitoring.

capacitor. The RST output is guaranteed to be in the

correct state for V down to 1V and may be disabled

during supply margin testing. Each status output has a

weak internal pull-up and may be externally pulled up to

an external voltage.

APPLICATIONS

■

Desktop and Notebook Computers

■

Multivoltage Systems

The 52μA supply current makes the LTC2932 ideal for

power conscious systems and the part may be conﬁgured

to monitor less than six inputs.
