1.0A pFET Load Switch
Description
SLG59M1730C
An Ultra-small 33 mΩ, 1.
0 A pFET Load Switch
with Controlled Inrush Current Profile
General Description
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 load 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 load 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 Renesas’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.

Type Pin Description
Input MOSFET
A low-to-high transition on this pin initiates the operation of the SLG59M1730C.
ON is an asserted HIGH, level-sensitive CMOS input with VIL < 0.
3 V and VIH > 0.
85 V.
As the ON pin input circuit does not have an internal pull-down resistor, connect this pin to a general-purpose output (GPO) of a microcontroller, an application processor, or a system controller – do not allow t...
