Smart cartridge wake up operation and data retention
An electronic system for a surgical instrument is disclosed. The electronic system comprises 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. A short circuit protection circuit coupled between the main power supply circuit and the supplementary power supply circuit. 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. 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.
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.
2. The electronic system of claim 1 , wherein the short circuit protection circuit is configured to monitor one or more short circuit conditions.
3. The electronic system of claim 1 , comprising a plurality of supplementary protection circuits networked together to isolate, detect, or protect other circuit functions.
4. 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
an over current/voltage protection circuit coupled between the main power supply circuit and the supplementary power supply circuit, wherein the over current/voltage protection circuit is configured to isolate current from the main power supply circuit when the secondary circuit experiences higher levels of current or voltage than expected.
5. The electronic system of claim 4 , wherein the over current/voltage protection circuit is configured to lockout the firing of the surgical instrument when the over current/voltage condition event is indicated, when an over current/voltage condition is detected.
6. The electronic system of claim 4 , wherein the over current/voltage protection circuit is configured to indicate an over current/voltage condition to an end user of the surgical instrument, when an over current/voltage condition is detected.
7. The electronic system of claim 4 , wherein the over current/voltage protection circuit is configured to lock-out the surgical instrument from being fired or lock-out other operations of the surgical instrument, when an over current/voltage condition is detected.
