onsemi FPF3380UCX, 1, OVP Load Power Switch IC 12-Pin, WLCSP

FPF3380UCX is an OVP with integrated ultra-low on-resistance single channel switch. The device contains an N-MOSFET that can operate over an input voltage range of 2.8V to 23V and can support a maximum continuous current of 5A.
When the input voltage exceeds the over-voltage threshold, the internal FET is turned off immediately to prevent damage to the protected downstream components.
The device has integrated ±110V surge protection TVS.
FPF3380 is available in a small 12-bumps WLCSP package and operates over the free-air temperature range of -40°C to +85°C

Surge Protection: integrated TVS ±110V for IEC61000-4-5
Internal Low RDS(on) NMOS Transistors: Typical 15mΩ
Over-Voltage Protection (OVP) up to +28V
Programmable Over-voltage Lockout (OVLO): externally adjustable via OVLO pin
