NOTES:
1. Adjust VCC above the start threshold before setting at 10 V.
2. Oscillator frequency for the UCC2813-0, UCC2813-2, and UCC2813-3 is the output frequency.
Oscillator frequency for the UCC2813-1, UCC2813-4, and UCC2813-5 is twice the output frequency.
3. Gain is defined by: A =
VCS
4. Parameter measured at trip point of latch with pin 2 at 0 V.
5. Total variation includes temperature stability and load regulation.
6. Start threshold, stop threshold, and Zener shunt thresholds track one another.
7. Not production tested.
8. The device is fully operating in clamp mode as the forcing current is higher than the normal operating supply current.
ICC = 10 mA,
