NOTES: 2. Adjust VCC above the startup threshold before setting to 12V.
3. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
4. This parameter is measured at the latch trip point with IFB = –5.0 µA, refer to Figure 9.
5. Comparator gain is defined as AV = ∆V Compensation
