APPLICATION NOTE

In the UTC TA31002 the initiation current consumption (Isi) can be changed by using the RSL terminal.

The

resistor RSL is connected to GND from PIN2 as shown in fig.1.

Further, the initation current consumption (Isi) can

be changed by changing the value of RSL.

Fig.2 show the graph of Vs-Is characteristic at the time when RSL has been changed to three values.

The Vs-Is

characteristic in UTC TA31002 at the time when RSL=6.8k

Ω coincides with that at the time when PIN2 of the

TA31001 has been used at an open state.
