MAX4925 Datasheet PDF - Maxim Integrated

Description

●The MAX4923–MAX4926 overvoltage protection (OVP) controllers protect low-voltage systems against high-voltage faults of up to +28V with an appropriate external pFET. 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.

●The input (IN) is ESD protected to ±15kV HBM when bypassed to ground with a 1µF ceramic capacitor. All devices are offered in a small, 6-pin (1.5mm x 1.0mm) µDFN package and are specified over the extended -40°C to +85°C temperature range.
