In-Rush Current Limit MOSFET Driver
FEATURES
• 2.9- to 13-V Input Operating Range
• Microprocessor RESET
• Integrated High-Side Driver for N-Channel MOSFET
• Programmable di/dt Current
DESCRIPTION
The Si9750 current limit MOSFET interface IC is designed to
operate between a power source and a load using a low on-
resistance 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).
