Sawtooth OSC circuit consists of Q1 through Q4 and R1 through R3.
R1 and R2 are voltage divider of 5 V build−in regulator.
Q1 is turned “off” when V4 is less than the voltage of 2.5 V + VBE Q4 + VBE Q3 approximately equal to 3.8 V. V4
is increased by C1 charging of I4. Q1 and Q2 are turned “ON” when V4 becomes V4 − H level.
Lower level of V4 (V4 − L) is equal to VBE Q4 + VBE Q3 + VSAT Q1 approximately equal to 1.5 V.
V4 is calculated by following equation.
V4 = 5·(1 − e −

Assuming that V4 = 1.5 V (t = t1) and=3.8 V (t = t2).
C1 is external capacitance connected to Pin (4) (or (5)) and R3 is on−chip 20 kΩ resistor.
Therefore, OSC frequency is calculated as follows.
t1 = −C1·R3·1n (1 −
