Abstract

An implantable medical device can include an integrated circuit comprising an electrostatic discharge (ESD) protection circuit. The ESD protection circuit can include an active circuit, a first passive circuit, and a second passive circuit. For example, at least one of the first or second passive circuits can include an array of capacitors in a series configuration, a parallel configuration, or a combination of series and parallel configurations. The first and second passive circuits can be configured to establish a specified time constant, and, in response to an applied ESD, the first and second passive circuits can provide a control signal to active circuit to switch the active circuit from a substantially non-conductive mode to a substantially conductive mode.

First claim

The claimed invention is:

1. An implantable medical device, comprising:
a housing;
an integrated circuit included in the housing, the integrated circuit comprising an electrostatic discharge (ESD) protection circuit including:
an active circuit configured to selectively electrically couple a first power supply node to a second power supply node in response to a control signal received via a control input of the active circuit, the active circuit including a drive circuit or a c…
