SGM40659/SGM40660/SGM40661

Adjustable Over-Voltage Protection Switches

GENERAL DESCRIPTION

FEATURES

The SGM40659/60/61 are over-voltage protection

devices designed to protect low voltage systems from

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

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

● Integrated Switch On-Resistance: 27mΩ (TYP)

● Current Capability up to 4A

● Internal Over-Voltage Protection Thresholds:

 Fixed 15.61V (SGM40659)

The integrated 27mΩ (TYP) R_ONFET allows it to pass

through 4A 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.

 Fixed 6.80V (SGM40660)

 Fixed 5.94V (SGM40661)

● Wide Adjustable OVLO Threshold Range:

4V to 20V

If the OVLO input is connected to GND, the

SGM40659/60/61 automatically choose the internal

OVLO thresholds that are preset to 15.61V/

6.80V/5.94V (SGM40659/60/61) typically.

● Surge Immunity up to +40V

● Debounce Time: 15ms

● Switch Turn-Off Time: 80ns

● Under-Voltage Lockout Protection

● Short-Circuit Protection

The SGM40659/60/61 are available in a Green

WLCSP-1.30×0.94-6B package, and operate over an

ambient temperature range of -40℃ to +85℃.

● Thermal Shutdown Protection

● -40℃ to +85℃ Operating Temperature Range

● Available in a Green WLCSP-1.30×0.94-6B Package
