Note 1: Inhibits boost switching if SUP exceeds the overvoltage threshold. Switching resumes when SUP drops below the threshold.
Note 2: Boost switching is not enabled until SUP is above undervoltage threshold.
Note 3: Guaranteed by design, not production tested.
Note 4: -40°C specifications are guaranteed by design, not production tested.
