Note 4: Oscillator frequency for the UCCx800, UCCx802 and UCCx803 is the output frequency. Oscillator frequency for the UCCx801, UCCx804 and UCCx805 is twice the output frequency. Note 5: Gain is defined by: A V V VV COMP CS CS =≤ ≤ ∆ ∆ 00 8 . . Note 6: Parameter measured at trip point of latch with Pin 2 at 0V. Note 7: Total Variation includes temperature stability and load regulation. Note 8: Start Threshold, Stop Threshold and Zener Shunt Thresholds track one another. Note 9: Guaranteed by design. Not 100% tested in production. Note 10: The device is fully operating in clamp mode as the forcing current is higher than the normal operating supply current. |
