SGM40675A数据手册SGMICRO中文资料规格书

描述 Description

The SGM40675A is an over-voltage protector with a complete set of protection functions. In low-voltage system applications, the OUT terminal can effectively prevent power supply failures up to 28V. Moreover, there is an internal clamping design that protects the product from surge events of up to ±100V. The SGM40675A incorporates a 25mΩ low RON N-MOSFET to facilitate efficient current flow from IN to OUT.
Whenever the input voltage is higher than the over-voltage threshold, the internal MOSFETs are automatically shut down to prevent over-voltage from causing harm to downstream devices. The two OVP threshold voltages (12.9V/23V) can be programmed through VP pin. The over-voltage protection function can ensure the safe operation of surge events in any state. Additionally, it supports reverse bias blocking, when the device is turned off, the reverse protection function is activated. This function effectively prevents any voltage flowing from the OUT pin to the IN pin.
To further enhance protection, the SGM40675A has improved ESD and thermal protection function against overload conditions.
The SGM40675A is available in a Green WLCSP-2.27×1.86-20B package.
