Using a proprietary MOSFET design, the SLG59M1658V
achieves a stable 17 mΩ RDSON across a wide input voltage
range. In addition, the SLG59M1658V’s package also exhibits
low thermal resistance for high-current operation using
Silego’s proprietary CuFET technology.
Fully specified over the -40 °C to 125 °C temperature range,
the SLG59M1658V is packaged in a space-efficient, low
thermal resistance, RoHS-compliant 1.0 mm x 1.6 mm STDFN
package.

SLG59M1658V
The SLG59M1658V is a high performance 17 mΩ, 2.5 A
single-channel nFET integrated power switch which can
operate with a 2.5 V to 5.5 V VDD supply to switch power rails
from as low as 0.9 V up to the supply voltage. The
SLG59M1658V incorporates two-level overload current
protection, thermal shutdown protection, fast output voltage
discharge, and in-rush current control which can easily be
adjusted by a small external capacitor.

Pin Description
1
VDD
PWR
With an internal 1.8 V UVLO threshold, VDD supplies the power for the
operation of the power switch and internal control circuitry. Bypass the VDD
pin to GND with a 0.1 µF (or larger) capacitor.
2
ON
Input
A low-to-high transition on this pin initiates the operation of the
SLG59M1658V’s state machine. ON is a CMOS input with VIL < 0.25 V
and VIH > 0.85 V thresholds. While there is an internal pull-down circuit to
GND (~4 MΩ), connect this pin directly 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.
3, 4
D
MOSFET
Drain terminal connection of the n-channel MOSFET (2 pins fused for VD).
Connect at least a low-ESR 0.1 µF capacitor from this pin to ground.
Capacitors used at VD should be rated at 10 V or higher.
5, 6
S
MOSFET
Source terminal connection of the n-channel MOSFET (2 pins fused for
VS). Connect a low-ESR capacitor from this pin to ground and consult the
Electrical Characteristics table for recommended CLOAD range. Capacitors
used at VS should be rated at 10 V or higher.
7
CAP
Input
A low-ESR, stable dielectric, ceramic surface-mount capacitor connected
from CAP pin to GND sets the VS slew rate and overall turn-on time of the
SLG59M1658V. For best performance CSLEW value should be ≥ 1.5 nF
and voltage level should be rated at 10 V or higher.

SLG59M1658V Power-Up/Power-Down Sequence Considerations
To ensure glitch-free power-up under all conditions, apply VDD first, followed by VD after VDD exceeds 1 V. Then allow VD to reach
90% of its max value before toggling the ON pin from Low-to-High. Likewise, power-down in reverse order.
If VDD and VD need to be powered up simultaneously, glitching can be minimized by having a suitable load capacitor. A 10 μF
CLOAD will prevent glitches for rise times of VDD and VD less than 2 ms.
If the ON pin is toggled HIGH before VDD and VD have reached their steady-state values, the IPS timing parameters may differ
from datasheet specifications.
The slew rate of output VS follows a linear ramp set by a capacitor connected to the CAP pin. A larger capacitor value at the CAP
pin produces a slower ramp, reducing inrush current from capacitive loads.
SLG59M1658V Current Limiting
The SLG59M1658V has two modes of current limiting, differentiated by the output (Source pin) voltage.
1. Standard Current Limiting Mode (with Thermal Protection)
When V(S) > 250 mV, the output current is initially limited to the Active Current Limit specification given in the Electrical Characteristics table. The current limiting circuit is very fast and responds within a few micro-seconds to sudden loads. When overload
is sensed, the current limiting circuit increases the FET resistance to keep the current from exceedng the Active Current Limit.
However, if an overload condition persists, the die temperature rise due to the increased FET resistance while at maximum current
can activate Thermal Protection. If the die temperature exceeds the THERMON specification, the FET is shut completely OFF,
allowing the die to cool. When the die cools to the THERMOFF temperature, the FET is allowed to turn back on. This process may
repeat as long as the overload condition is present.
2. Short Circuit Current Limiting Mode (with Thermal Protection)
When V(S) < 250 mV (which is the case with a hard short, such as a solder bridge on the power rail), the current is limited to
approximately 500 mA. Thermal Protection is also present, but since the Short Circuit Current Limit is much lower than Standard
Current Limit, activation may only occur at higher ambient temperatures.
