FA7632

The FA7632 is an e-fuse controller for 5V to 20V system. The programmable current limit protects the power source from over-current or short-circuits conditions. The device is controlled by an on/off input, which is capable of interfacing directly with low-voltage control signals. In FA7632, an option 2kΩ on-chip load resistor is added for output discharge when the switch is turned off.
Other features include a power-OK (POK) output that signals when the output voltage is ready.
With an appropriate external MOSFET, FA7632 can support 20V@15A applications up to 300 Watts.
