  • Patent number: 11955796
    Abstract: An output circuit included in an integrated circuit may employ multiple protection circuits to protect driver devices from damage during an electrostatic discharge event. One protection circuit clamps a signal port to a ground supply node upon detection of the electrostatic discharge event. Another protection circuit increases the voltage level of a control terminal to one of the driver devices during the electrostatic discharge event to reduce the voltage across the driver device and prevent damage to the device.

  • Patent number: 11191155
    Abstract: Tamper-respondent assemblies are provided which include a circuit board, an enclosure assembly mounted to the circuit board, and a pressure sensor. The circuit board includes an electronic component, and the enclosure assembly is coupled to the circuit board to enclose the electronic component within a secure volume. The enclosure assembly includes an enclosure with a sealed inner compartment, and a structural material within the sealed inner compartment of the enclosure. The structural material within the enclosure inhibits deflection of the enclosure due to a pressure differential between pressure of the sealed inner compartment and pressure around, at least in part, the enclosure. The pressure sensor senses pressure within the sealed inner compartment of the enclosure to facilitate identifying a pressure change indicative of a tamper event.
