OVD does not go High. Please provide any advice.
#68 pin: OVD_CH0 and #8 pin: OVD_CH1 does not go High.
1) Is OVD_CH0 and OVD_CH1 open drain? (Pull-up is applied in our PCB.)
2) Following register setting correct? (It is expected that OVD_CH0 and OVD_CH1 goes High by following register setting.)
ADDRESS DATA description
0x01 0x2332 Set DVH to +3.0V.
0x0A 0x1FFF Set OVD high level to +2.5V.
0x12 0x001 Enable OVD alarm flag.
3) Please advise if there are other points to consider.
Reading ADDRESS 0x13 by changing input signal state:
1 = DUT voltage > OVD high voltage
0 = DUT voltage < OVD high voltage
Above states are observed, however OVD_CH0 and OVD_CH1 output is Low level in both cases.
