In-Rush Current Limit MOSFET Driver

FEATURES

D 2.9- to 13-V Input Operating Range

D Microprocessor RESET

D Integrated High-Side Driver for N-Channel MOSFET

D 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).

The Si9750 is available in both standard and lead (Pb)-free

packages.
