Product details
Overview
SLG5NT1594V from Silego Technology, Inc. is an integrated P-channel load switch IC with a single 1.0 A rated MOSFET, 28.5 mΩ RDS(ON) at 5.0 V, ultra-low quiescent current (0.02 μA typical OFF-state), and operation across 1.5–5.5 V input range-designed for space-constrained portable power rail control.
For engineers reviewing the SLG5NT1594V datasheet, SLG5NT1594V pinout, SLG5NT1594V application, or SLG5NT1594V equivalent, key selection criteria include low-voltage operation down to 1.5 V, fixed slew-rate control for inrush suppression, STDFN 4L 1.0 × 1.0 mm package footprint, and industrial temperature range (−40 °C to +85 °C).
Technical Context
The SLG5NT1594V integrates a single P-channel MOSFET with gate drive logic and fixed-slew-rate control to limit inrush current during turn-on. It operates without external components and requires only one ON control signal.
Its RDS(ON) varies predictably with VIN (77.6 mΩ at 1.5 V, 28.5 mΩ at 5.5 V), and total turn-on time ranges from 114 μs (VIN = 5 V) to 332 μs (VIN = 1.5 V) into a 10 Ω load with 0.1 μF output capacitance.

FAQ
What is the maximum continuous output current rating for the SLG5NT1594V?
The SLG5NT1594V is rated for 1.0 A continuous output current across its full operating temperature range (−40 °C to +85 °C). This rating assumes proper PCB thermal design and is supported by its 0.5 W package power dissipation limit and measured RDS(ON) values. Peak current capability is 1.5 A for ≤1 ms pulses at 1% duty cycle.
Does the SLG5NT1594V require external components for basic operation?
No, the SLG5NT1594V operates as a fully integrated load switch with no external components required for core functionality. Its fixed slew-rate control, internal gate drive, and logic-level ON pin eliminate the need for RC networks or level shifters. A 0.1 μF capacitor from VOUT to GND is recommended to suppress output glitches during fast VIN ramps.
What is the minimum input voltage at which the SLG5NT1594V remains functional?
The SLG5NT1594V operates down to 1.5 V input voltage, with confirmed RDS(ON) of 77.6 mΩ (typical) and total turn-on time of 332 μs (typical) at this rail. Its ON pin logic thresholds scale with VIN, ensuring reliable enable/disable behavior across the entire 1.5–5.5 V range.
How does the SLG5NT1594V manage inrush current during turn-on?
The SLG5NT1594V incorporates fixed internal slew-rate control that limits the dV/dt on the VOUT pin, thereby suppressing inrush current without external circuitry. Measured rise times range from 92 μs (VIN = 5.0 V) to 253 μs (VIN = 1.5 V) into a 0.1 μF capacitive load, providing consistent inrush mitigation across operating voltages.
Is the SLG5NT1594V RoHS-compliant and lead-free?
Yes, the SLG5NT1594V is Pb-free, halogen-free, and RoHS-compliant per its official datasheet (Rev 1.00, Dec 2016). It uses a green STDFN 4L package with standard reflow profile compliance per IPC/JEDEC J-STD-020, and the top marking includes a pin-1 identifier and serial number per package marking specification.
