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  
CC  
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.
