In one example, the core power domain having a first voltage (CX) should power up before the I/O power domain having a second voltage (PX), where PX>CX. If PX ramps up before CX, the POC circuit produces a signal indicating an improper power-up sequence, which causes the I/O pads to be placed in a known state. After CX subsequently ramps up, the POC circuit returns to a passive (LOW) state. If CX should subsequently collapse while PX is still up, the POC circuit remains LOW until PX also collapses."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Latch-based power-on checker","description":"A latch-based power-on checker (POC) circuit for mitigating potential problems arising from an improper power-up sequence between different power domains (e.g., core and input/output (I/O)) on a syste","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9800230","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
