Function

Power supply

• Common

3

VCC

Output pin for internal constant-voltage circuit; connected to decoupling capacitor

2

IREF

Pin for connection to resistor to set constant current for internal circuits; approx. 1.3 V

1

GND

Ground

• Op-amp

13

CPI–

Op-amp input pins

15

CPI+

14

C1

Pin for connection to capacitors to prevent noise-induced erroneous operation; connected

between pins [13], [14] and pins [15], [14]

12

C2

Pin for connection to capacitor to prevent oscillation; connected with pin [11].

11

OPAO

Op-amp output pin

• Leakage detection, SCR driving circuit

9

VREF

Input reference level pin for leak detection circuit; approx. 2.4 V

10

ILKI

Another input pin for leak detection circuit

5

TRC1

Pin to connect a capacitor used to integrate the level discriminator output signal of the leak input

signal

6

TRC2

Pin to connect a capacitor for noise elimination

4

OFFC

When leak input signal is not continued

When a leak is detected and SCR is turned on

After a prescribed amount of time, this IC is returned to the initial state.

A capacitor to set the time for this function is connected.

7

DRYC

Pin to connect a capacitor to set the time when using the time delay function

8

SCRT

Thyristor driving output pin
