ELECTRICAL CHARACTERISTICS (continued)

T
Note 1: V
Note 2: SDO automatically goes low when the UVLO pin drops below its threshold (or V
Note 3: This undervoltage lockout disables the MAX5039/MAX5040 at V
Note 4: In order to regulate correctly, V
Note 5: I/O and CORE valid mean the voltages on these pins have settled within their target specifications for normal operation.
Note 6: CORE and I/O supplies rise and fall rates must be limited to less than 6.6V/µs.
Note 7: POK does not deassert for glitches less than t
Note 8: A fault condition is latched when either of the two following conditions maintains for longer than t
