1. An electronic system for a surgical instrument, the electronic system comprising:
- a main power supply circuit configured to supply electrical power to a primary circuit;
a supplementary power supply circuit configured to supply electrical power to a secondary circuit; and
a short circuit protection circuit coupled between the main power supply circuit and the supplementary power supply circuit;
wherein the supplementary power supply circuit is configured to isolate itself from the main power supply circuit when the supplementary power supply circuit detects a short circuit condition at the secondary circuit; and
wherein the supplementary power supply circuit is configured to rejoin the main power supply circuit and supply power to the secondary circuit, when the short circuit condition is remedied.
