When the input voltage exceeds the overvoltage lockout (OVLO) threshold, or falls below the undervoltage lockout (UVLO) threshold, these devices turn off the pFET to prevent damage to protected components and issue a flag to notify the processor of a fault condition. The typical overvoltage trip level is set to 7.18V (MAX4923), 6.16V (MAX4924), 5.65V (MAX4925), and 4.46V (MAX4926). The undervoltage trip level is set to 2.44V (typ) for all devices.
