Designed to operate over a -40°C to 85°C range, the
SLG59M1649V is available in a RoHS-compliant, ultra-small
1.0 x 1.6 mm STDFN package.
Features
SLG59M1649V
The SLG59M1649V is a self-powered, high-performance,
23 mΩ pFET integrated power switch designed for 1.5 to 5 V
power rail applications up to 4 A. When enabled, internal
reverse-current protection will quickly open the switch in the
event of a reverse-voltage condition is detected
(a VOUT+50mV > VIN condition opens the switch). Upon the
detection of a reverse condition, an open-drain FAULT output
is asserted. In the event the VIN voltage is too low, the power
switch also contains an internal UVLO threshold monitor to
keep or to turn the switch OFF.

Pin Description
Power/Input
With an internal 1.2V UVLO threshold, VIN supplies the power for the
operation of the power switch, the internal control circuitry, and the source
terminal of pFET. Bypass the VIN pin to GND with a 2.2 μF (or larger),
low-ESR capacitor.
A low-to-high transition on this pin initiates the operation of the power
switch. ON is an asserted-HIGH, level-sensitive CMOS input with
VIL < 0.3 V and VIH > 1 V. As the ON input circuitry does not have an internal
pull-down resistor, connect the ON pin directly to a GPIO controller – do
not allow this pin to be open circuited.

An open drain output, FAULT is asserted within TFAULTLOW when a
(VOUT+VREVERSE > VIN) condition is detected. The FAULT output is deasserted within TFAULTHIGH when the fault condition is removed. Connect
an external 10-kΩ resistor from the FAULT pin to the system’s local logic

VIN Inrush Current Details
When the SLG59M1649V is enabled with ON ↑, the power switch closes to charge the VOUT output capacitor to VIN. The charging
current drawn from VIN is commonly referred to as “VIN inrush current” and can cause the input power source to collapse if the
VIN inrush current is too high.
Since the VOUT rise time of the SLG59M1649V is fixed, VIN inrush current is then a function of the output capacitance at VOUT.
The expression relating VIN inrush current, the SLG59M1649V VOUT rise time, and CLOAD is:
VIN Inrush Current = CLOAD x
∆VOUT
VOUT Rise Time
where in this expression ∆VOUT is equivalent to VIN if the initial SLG59M1649V’s output voltages are zero.
In the table below are examples of VIN inrush currents assuming zero initial charge on CLOAD as a function of VIN.

Inrush Current
1.5 V
66 μs
0.1 μF
2.3 mA
5V
130 μs
0.1 μF
3.8 mA
Since the relationship is linear and if CLOAD were increased to 1 µF, then the VIN inrush currents would be 10x higher in either
example. If a large CLOAD capacitor is required in the application and depending upon the strength of the input power source, it
may very well be necessary to increase the CIN-to-CLOAD ratio to minimize VIN droop during turn-on.
For other VOUT rise time options, please contact Silego for additional information.
Power Dissipation
The junction temperature of the SLG59M1649V 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 SLG59M1649V 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)

SLG59M1649V
Power Dissipation (continued)
In nominal operating mode, the SLG59M1649V’s power dissipation can also be calculated by taking into account the voltage drop
across each switch (VIN-VOUT) and the magnitude of that channel’s output current (IOUT):
PDTOTAL = (VIN-VOUT) x IDS or
PDTOTAL = (VIN – (RLOAD x IDS)) x IDS
where:
PDTOTAL = Total package power dissipation, in Watts (W)
VIN = Input Voltage, in Volts (V)
RLOAD] = Output Load Resistance, in Ohms (Ω)
IDS = Output current, in Amps (A)
VOUT= Output voltage, or RLOAD x IDS
