Circuits
  • LVDR: Monitors the power-supply voltage, and generates an internal reset signal when the voltage falls below a specified value.
  • LVDI: Monitors the power-supply voltage, and generates an interrupt when the voltage falls below or rises above respective specified values.
  • Voltage can be selected from 12 levels.
