OSC frequency calculation
VOSC is increased by COSC charging through the constant current source (150 A).
VOSC is calculated by following equation.

Q2 is turned “off” when VOSC is less than the voltage of 1.35 V + VBE (Q2) approximately equal to
2.05 V.
Q3 and Q4 are turned “on” when VOSC becomes 2.05 V.
VOSC (H) = VBE (Q2) + 1.35
≈ 2.05 V
Lower level of V (22) pin is equal to VBE (Q2) + VCE (SAT) (Q4) approximately equal to 1.0 V.
VOSC (L) = VBE (Q2) + VCE (SAT) (Q4)
≈ 1.0 V
Assuming that VOSC = 1.0 V (t = t1) and = 2.05 V (t = t2), OSC frequency is calculated as follows.
