Introduction

The SGM40653/4/5 are over-voltage protection devices designed to protect low voltage systems from damage with a high voltage supply up to +28VDC. The SGM40653/4/5 can withstand surges up to +120V without damage. The integrated 62mΩ (TYP, CSP package)/73mΩ (TYP, TDFN package) RON FET allow it to pass through 4.5A continuous current. The FET is turned off when the input voltage exceeds the over-voltage threshold which can be adjusted between 4V and 20V with optional external resistors. If the OVLO input is set below the external OVLO select threshold, the SGM40653/4/5 automatically choose the internal trip thresholds that are preset to 15.39V/6.8V/ 5.81V (SGM40653/4/5) typically. The open-drain ACOK output indicates a stable power supply between minimum supply voltage and V0VLO. The SGM40653/4/5 also have enable control to reduce power consumption. The SGM40653/4/5 are available in Green TDFN3×3-12L and WLCSP- 1.30×1.83-12B packages, and operate over an ambient temperature range of -40°C to +85°C.
