Si9750 General Description
The Si9750 current limit MOSFET interface IC is designed to operate between a power source and a load using a low onresistance power MOSFET with a sense terminal or in conjunction with a low ohmic sense resistor. The Si9750 current limiter prevents source and load transients during hot swap and power-on with programmable dv/dt and di/dt. Both turn-on and steady-state current limits can be individually programmed, providing protection against short circuits. Power on RESET and logic controls allow complete microprocessor interfacing. The RESET function of the Si9750 is industry-standard with full programmability.
The Si9750 is available in a 16-pin SOIC package and is rated over the commercial temperature range (0 to 70°C).
