(3) Constant current control

Integrating current II can be obtained based on the reference voltage (1.22 V) by the built-in high-precision

generator and resistance RI.

II =

(A) .................... (1)

1.22

Integration time TI can be calculated as follows;

TI = (VIN + 0.49)

.................. (2)

However, parameters such as built-in comparator offset voltage, analog switch offset, voltage leak current and delay

time are not counted.

TDE

Reset supply voltage

VRE

RESET output

When voltage applied to pin VRE becomes less than 4.45 V, the RESET output status becomes "L". If voltage

increases over 4.50 V, the

RESET status becomes "H" within 150 µs.
