3 Descriptions

The NU5721 is an over-voltage protection device

designed to protect low voltage systems from damage

caused by voltage surges. The NU5721 can withstand

surges up to +/-120V without damage. The integrated

R_ONFET allows it to pass through 6A

continuous current. The FET is turned off when the

input voltage exceeds the over-voltage threshold

which can be adjusted from 4V to 20V with optional

external resistors. If the OVLO input is set below the

external OVLO select threshold, the NU5721

automatically choose the internal trip threshold which

is preset to 6.8V typically. The open drain

output indicates a stable power supply voltage which

is within V_UVLOand V_OVLO. The NU5721 also has

enable/disable control function to reduce power

consumption. The NU5721 are available in FCQFN-

1.30×1.80-12B packages, and operate over an ambient

±15 kV Air Gap Discharge
