Abstract
A fail-safe device may be coupled to a main device for actuating a switch responsive to a failure. The fail-safe device may include a fail-safe circuit, and an isolation trench surrounding the fail-safe circuit and isolating the fail-safe circuit from the main device. The fail-safe device may include an internal power supply connection, an internal reference voltage connection, a self-biased drive block configured to drive the at least one switch, and a receiver configured to receive failure signals from the main device.
