Patent ID: 11742653

Abstract:
An integrated circuit breaker includes a solid state switching module (SSWM) configured to receive and switchable control a line power (LP) for a given phase, and output a first switched power (SP) to a load. A first sensor (LPS) senses LP currents. A second sensor (SPS) senses SP currents. A power module controls operating states of the SSWM based upon LPS and SPS reading(s). The LPS and/or the SPS may also sense temperatures. The power module includes a high voltage domain, isolated from a low voltage domain, that includes a gate driver coupled to the SSWM and a high voltage controller providing drive signals to the gate driver. The low voltage domain includes an LP monitor and an SP monitor that detects anomalous LP and/or SP conditions and communicates error signals to the high voltage domain and to users for reporting, diagnostic, and/or other purposes via an external communications module.
