Using a proprietary MOSFET design, the SLG59M1736C
achieves a low RDSON across the entire input voltage range.
Through the application of Renesas’s proprietary CuFET
technology, the SLG59M1736C can be used in applications up
to 2.2 A with a very-small 0.64 mm2 WLCSP form factor.

Pin Description
Input
A low-to-high transition on this pin initiates the operation of the SLG59M1736C. ON is
an asserted HIGH, level-sensitive CMOS input with ON_VIL < 0.3 V and
ON_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 this pin to be open-circuited.
In order to activate the SLG59M1736C’s controlled inrush current control circuitry, ON
shall be toggled HIGH only after VIN is higher than the SLG59M1736C’s VSUCC(TH)
specification.

An Ultra-small 33 mΩ, 2.2 A pFET
Load Switch with Controlled Inrush Current
Applications Information
SLG59M1736C Nominal Operation
During VIN power-up operation, the SLG59M1736C’s internal inrush current Start-up Control circuit is activated once VIN reaches
90% of its nominal voltage (Please see VSUCC(TH) specification). Once VIN has reached this threshold (within the SLG59M1736C’s
nominal input range of 2.5 V to 5.5 V), the ON pin can be toggled LOW-to-HIGH to close the switch. Nominal power-off sequence
is performed in reverse: that is, the ON pin is toggled HIGH-to-LOW to open the switch before VIN is powered down/turned OFF.
SLG59M1736C VIN Inrush Current Limit on Startup
During startup, the current passing through the power FET is internally limited to a maximum specified by IRISE in the EC table.
To prevent incomplete start-up, the SLG59M1736C shall be powered up only with a capacitive load CLOAD attached to the VOUT
pin. After VOUT ramps up to its nominal voltage, a resistive load (RLOAD) can be applied to the load switch.
Slew Rate Calculation
During the rise of VOUT, the SLG59M1736C limits the output current to IRISE. With a capacitor CLOAD attached to VOUT, the
equation below provides the nominal value for the slew rate:
IRISE
Slew Rate =
CLOAD
Power Dissipation Considerations
The junction temperature of the SLG59M1736C depends on factors such as board layout, ambient temperature, external air flow
over the package, load current, and the RDSON-generated voltage drop across each power MOSFET. While the primary
contributor to the increase in the junction temperature of the SLG59M1736C is the power dissipation of its power MOSFETs, its
power dissipation and the junction temperature in nominal operating mode can be calculated using the following equations:
PDTOTAL = RDSON x IDS2
where:
PDTOTAL = Total package power dissipation, in Watts (W)
RDSON= Power MOSFET ON resistance, in Ohms (Ω)
IDS = Output current, in Amps (A)
and
TJ = PDTOTAL x θJA + TA
where:
TJ = Die junction temperature, in Celsius degrees (°C)
θJA = Package thermal resistance, in Celsius degrees per Watt (°C/W) – highly dependent on pcb layout
TA = Ambient temperature, in Celsius degrees (°C)
In nominal operating mode, the SLG59M1736C’s power dissipation can also be calculated by taking into account the voltage drop
across the switch (VIN - VOUT) and the magnitude of the switch’s output current (IDS):
PDTOTAL = (VIN - VOUT) x IDS or
PDTOTAL = (VIN – (RLOAD x IDS)) x IDS
where:
PDTOTAL = Total package power dissipation, in Watts (W)
VIN = Switch input Voltage, in Volts (V)
RLOAD = Output Load Resistance, in Ohms (Ω)
IDS = Switch output current, in Amps (A)
VOUT = Switch output voltage, or RLOAD x IDS

Layout Guidelines:
1. Since the VIN and VOUT pins dissipate most of the heat generated during high-load current operation, it is highly recommended
to make power traces as short, direct, and wide as possible. A good practice is to make power traces with absolute minimum
widths of 15 mils (0.381 mm) per Ampere. A representative layout, shown in Figure 7, illustrates proper techniques for heat to
transfer as efficiently as possible out of the device;
2. To minimize the effects of parasitic trace inductance on normal operation, it is recommended to connect input CIN and output
CLOAD low-ESR capacitors as close as possible to the SLG59M1736C's VIN and VOUT pins;
3. The GND pin should be connected to system analog or power ground plane.
SLG59M1736C Evaluation Board:
А GreenFET Evaluation Board for SLG59M1736C is designed according to the statements above and is illustrated on Figure 7.
Please note that evaluation board has D_Sense and S_Sense pads. They cannot carry high currents and dedicated only for
RDSON evaluation.
