VMON1_THRESHOLD

R/W

Threshold voltage for VMON1 input:

0x0 – 0.65V (high impedance input, external resistive divider can be

used)

0x1 – 0.80 V

0x2 – 1.00 V

0x3 – 1.10 V

0x4 – 1.20 V

0x5 – 1.30 V

0x6 – 1.80 V

0x7 – 1.80 V

To monitor any other voltage level, select 0x0 and use an external

resistive divider to scale down to 0.65 V. For other than 0x0 VMONx

input is low impedance (internal resistive divider enabled).

(Default from OTP memory)
