Voltage Supervisors

Cobham Voltage Supervisors

Cobham offers a new family of radiation-tolerant voltage supervisors for aerospace, military, and high reliability space applications.

The Voltage Supervisors can be used for power-on reset controllers for:
  • Microprocessors
  • Microcontrollers
  • FPGAs
  • ASICs
  • DSPs

The Voltage Supervisors can also be used to sequence multiple power supplies, with delays between application of each power supply and the final delay for bringing the part out of reset all precisely controlled by external capacitors.

There are 3.3V and 5V versions, as well as single and quad-channel versions. All Voltage Supervisors may be daisy-chained using the master reset capability, or may be wired in parallel using the open-drain outputs. The single channel Voltage Supervisors include a watch-dog timer. The quad channel Voltage Supervisors have over-voltage monitoring mode as well as under-voltage.

Voltage Supervisors can be used to control Cobham's Voltage Regulators.
