High-Current Over-Voltage Protector

GENERAL DESCRIPTION

FEATURES

The SGM40653/4/5 are over-voltage protection devices

designed to protect low voltage systems from damage

with a high voltage supply up to +28V_DC. The

SGM40653/4/5 can withstand surges up to +120V

without damage.

● Wide Power Supply Voltage Range: 2.5V to 28V

● Integrated Switch On-Resistance:

 62mΩ (TYP) (CSP Package)

 73mΩ (TYP) (TDFN Package)

● Internal Over-Voltage Protection Thresholds:

 15.39V (SGM40653)

The integrated 62mΩ (TYP, CSP package)/73mΩ (TYP,

TDFN package) R_ONFET 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.

 6.8V (SGM40654)

 5.81V (SGM40655)

● Wide Adjustable OVLO Threshold Range:

4V to 20V

● Surge Immunity up to +120V

● Debounce Time: 18.5ms

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.

● Soft-Start Function

● Enable Function

● Thermal Shutdown Protection

● -40℃ to +85℃ Operating Temperature Range

● Available in Green WLCSP-1.30×1.83-12B and

TDFN-3×3-12L Packages

The open-drain

output indicates a stable power

ACOK

supply between minimum supply voltage and V_OVLO

The SGM40653/4/5 also have enable control to reduce

power consumption.

APPLICATIONS

The SGM40653/4/5 are available in Green TDFN-

3×3-12L and WLCSP-1.30×1.83-12B packages, and

operate over an ambient temperature range of -40℃ to

+85℃.
