General Description
The MAX4959/MAX4960 overvoltage protection con-
trollers protect low-voltage systems against high-volt-
age faults of up to +28V. When the input voltage
exceeds the overvoltage lockout (OVLO) threshold,
these devices turn off an external pFET to prevent dam-
age to the protected components. The undervoltage
lockout (UVLO) threshold holds the external pFET off
until the input voltage rises to the correct level. An addi-
tional safety feature latches off the pFET when an incor-
rect low-power adapter is plugged in.
The MAX4959/MAX4960 control an external battery
switchover pFET (P2) (see Figures 4 and 6) that switches
in the battery when the AC adapter is unplugged. The
undervoltage and overvoltage trip levels can be adjusted
with external resistors.
The input is protected against ±15kV HBM ESD when
bypassed with a 1F ceramic capacitor to ground. All
devices are available in a small 10-pin (2mm x 2mm)
DFN and 10-pin MAX packages and are specified for
operation over the extended -40°C to +85°C temperature
range.
