Multivoltage Monitors

Monitor up to eight voltages with one device with industry-leading specifications for highest accuracy, lowest power, and smallest footprint.

Select From	Programming Method
Two Monitored Voltages	—	Resistor/capacitor adjustable	Factory fixed, pin selectable
Three Monitored Voltages	—	Resistor/capacitor adjustable	Factory fixed, pin selectable
Four Monitored Voltages	—	Resistor/capacitor adjustable	Factory fixed, pin selectable
Five or Six Monitored Voltages	I²C programmable	Resistor/capacitor adjustable	Factory fixed, pin selectable
Seven or More Monitored Voltages	I²C programmable	Resistor/capacitor adjustable	Factory fixed, pin selectable

• I²C Programmable
  Offering the highest functionality, integration, and flexibility, these devices allow adjustments "on the fly" or across multiple design platforms. EV kits and GUI software are available to assist with design and programming.
  
  
• Resistor/Capacitor Adjustable
  These devices allow a high degree of flexibility at a low cost. Most key functions can be adjusted simply with external resistors or capacitors.
  
  
• Factory Fixed, Pin Selectable
  Optimal when design parameters are known and minimizing board space/cost is paramount, these devices minimize the requirement for external components. Some devices offer pin-selectable functionality where the user gains flexibility by simply pulling pins high or low.
