TIC12400-Q1: /INT pin does not pull to low

Part Number: TIC12400-Q1
Other Parts Discussed in Thread: TMS570LS0914

Tool/software:

Hello,

I have interfaced this IC with TMS570LS0914 microcontroller. I am checking over voltage condition using this IC. 

I am facing below issues : 

1. /INT pin does not pull to low on Vs >= 37V.

2. OV flag in INT_STAT register not set to 1 even after OI (other interrupt) condition is triggered.

Below schematic is used. /INT pin is not connected to microcontroller. will that work ?

Configurations and initialization sequence are as below : 

1. CONFIG : 0X00

2. IN_EN : 0X00

3. CS_SELECT : 0X3CF

4. WC_CFG0 : 0X249249

5. MODE : 0X00

6. THRES COMP : 0X00

7. CONFIG : 0X800

Reading status at every 100ms interval.

Reading diagnostic at every 100ms interval.

Kindly guide me on this.

Thanks
