GaNSense Half-bridge ICs integrate over-temperature detection and protection (OTP) circuitry to protect the IC against excessively high junction temperatures (TJ).
High junction temperatures can occur due to overload, high ambient temperatures, and/or poor thermal management. Should TJ exceed the internal threshold then the IC will latch-off safely.
When TJ decreases again and falls below the internal threshold, the OTP latch will be reset. Until then, internal OTP latch is guaranteed to remain in the correct state while VCC is greater than 5 V.
