LTC2966  
100V Micropower Dual  
Voltage Monitor  
FEATURES  
DESCRIPTION  
The LTC®2966 is a low current, high voltage dual channel  
voltage monitor. Internal high value resistors sense the  
input monitor pins providing a compact and low power  
solution for voltage monitoring. Each channel includes  
two comparator reference inputs (INH/INL) to allow con-  
figuration of a high and low threshold using an external  
resistive divider biased from the on-chip reference. Range  
selection pins are provided for each channel to set the  
internal resistive dividers for 5x, 10x, 20x and 40x scaling.  
Thethresholdsarescaledaccordingtotherangeselection  
settings. Additionally, either INH or INL can be grounded  
to enable built-in hysteresis. Polarity selection pins allow  
each output to be inverted. The outputs are 100V capable  
and include a 500k pull-up resistor to an internal supply.
