NOTES:
1. Adjust VCC above the start threshold before setting at 15 V.
2. Not production tested.
3. Temperature stability, sometimes referred to as average temperature coefficient, is described by the equation:
Temp Stability =
VREF (max) – VREF (min)
TJ (max) – TJ (min)
. VREF (max) and VREF (min) are the maximum and minimum reference voltage measured
over the appropriate temperature range. Note that the extremes in voltage do not necessarily occur at the extremes in temperature.
4. Output frequency equals oscillator frequency for the UC2842A and UC2843A. Output frequency is one half oscillator frequency for the
UC2844A and UC2845A.
5. This parameter is measured with RT = 10 kΩ to VREF. This contributes approximately 300 µA of current to the measurement. The total
current flowing into the RT/C pin will be approximately 300 µA higher than the measured value.
6. Parameter measured at trip point of latch with VFB at 0 V.
7. Gain is defined by:
A =
