Typical Application
V_T1 = 1.250V x (R1)/(R1 + R2 + R3)
V_T2 = 1.250V x (R1 + R2)/(R1 + R2 + R3)
where:
(R1 + R2 + R3) = 27 kΩ and
V_{T1 or T2} = [6.20 mV/°C x T] + 395 mV therefore:
R1 = V_T1/(1.25V) x 27 kΩ
R2 = (V_T2/(1.25V) x 27 kΩ) − R1
R3 = 27 kΩ − R1 − R2

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
