SLG59M1730C
An Ultra-small 33 mΩ, 1.0 A pFET
Integrated Power Switch with Controlled Inrush Current
General Description
Pin Configuration
Pin A1 Index Mark
Operating from a 2.5 V to 5.5 V power supply, the
SLG59M1730C is a self-powered, high-performance 33 mΩ,
1.0 A single-channel pFET integrated power switch with a
controlled VIN inrush current profile. The SLG59M1730C’s low
supply current and controlled VIN inrush current profile makes
it an ideal pFET integrated power switch in small form-factor
personal health monitor and watch applications.

Using a proprietary MOSFET design, the SLG59M1730C
achieves a low RDSON across the entire input voltage range.
Through the application of Silego’s proprietary CuFET
technology, the SLG59M1730C’s can be used in applications
up to 1 A with a very-small 0.64 mm2 WLCSP form factor.
