E-Fuse MX6875 Electronic Fuse Current Limit Switch With Overvoltage Clamp Control For Notebook PC

Notebook PC MX6875 E-Fuse IC Current Limit Switch Overvoltage Clamp Controlled

The MX6875 family of electronic fuses are highly integrated circuit protection and power management solutions in small packages. The device uses very few external components and offers multiple protection modes. They are effective against overloads, short circuits, voltage surges and excessive inrush currents. The MX6875 is a programmable current limit switch with input voltage range selection and output voltage clamping. Extremely low RDS(ON) of the integrated protection N- channel FET helps to reduce power loss during the normal operation.

Applications with special voltage ramp requirements can use a single capacitor to program dVdT to ensure the proper output ramp rate. Independent enable control allows the complicated system sequencing control.

VCP

Output clamp voltage selection based on the input voltage. Pull VCPpinto High by

connecting a resistor to IN, or pull VCPpinto Low by connecting a resistor to ground, or float VCPpinto select different output clamping thresholds. Recommend to decoupling this pin with 0.1uF capacitor.
5 ILMT A resistor from this pinto GND will set the overload and short circuit limit.
6 dVdT Tie a capacitor from this pinto GND to control the ramp rate of OUT at device turn-on.
7 EN This is an ENABLE pin. When pulled down, it shuts off the internal pass MOSFET. When pulled high, it enables the device.
8 ,9 ,10 OUT Output of the device
GND Ground
