read through the R08h address, the content of the reg-
ister is left unchanged. When read through the CoR
R09h address, the register content will be cleared. A
reset sets R08h/R09h = 00h.
The MAX5935 continuously monitors the power supplies
and sets the appropriate bits in the supply event register
(Table 11). V
DD_OV

EE_OV
is set to 1 whenever

EE
exceeds its overvoltage threshold.
V
DD_UV
/V
EE_UV
is set to 1 whenever V
DD

EE
falls below
its undervoltage threshold.
OSC_FAIL is set to 1 whenever the amplitude of the
oscillator signal at the OSC_input falls below a level
that might compromise the AC disconnect detection
function. OSC_FAIL generates an interrupt only if at
least one of the ACD_EN (R13h[7:4]) bit is set high.
A thermal shutdown circuit monitors the temperature of
the die and resets the MAX5935 if the temperature
exceeds +150癈. TSD is set to 1 after the MAX5935
returns to normal operation. TSD is also set to 1 after
every UVLO reset.
When V
DD
and/or |V
EE
| is below its undervoltage-lock-
out (UVLO) threshold, the MAX5935 is in Reset mode
and securely holds all ports off. When V
DD
and |V
EE
|
rise to above their respective UVLO thresholds, the
device comes out of reset as soon as the last supply
