Operation over specified temperature range is tested for µMAX package. Note 2: Do not exceed absolute maximum rating; the ratio between the externally set OVLO and UVLO threshold must not exceed 4, [OVLO/UVLO]MAX ≤ 4. Note 3: Assertion delay starts from switching of CB pin to reaching of 80% of GATE1/GATE2 transition. This delay is measured without external capacitive load.
