1. An implantable medical device system, comprising:
a housing;
electrodes carried by the housing;
a transducer within the housing and configured to produce input voltage signals in response to receiving ultrasound energy; and
a circuit electrically coupled to the transducer and within the housing, wherein the circuit is configured to receive the input voltage signals and provide output voltage signals via an electrical pathway comprising the electrodes, the circuit including—
a switch on the electrical pathway, wherein the switch has an open state and a closed state; and
a slew rate detector configured to detect whether a voltage rate of an individual pulse of the input voltage signals exceeds a predetermined threshold rate,
wherein the circuit is configured to change the switch from the closed state to the open state in response to the detected voltage rate exceeding the predetermined threshold rate.
