Product details
Overview
SLG5NT1593V from Silego Technology (now part of Dialog Semiconductor) is a single-channel P-channel load switch IC with integrated discharge resistor, rated for 1.0 A continuous current and 28.5 mΩ RDS(ON) at 5.0 V, operating across 1.5–5.5 V input voltage range, used in portable power rail sequencing and battery-powered system load control.
For engineers reviewing the SLG5NT1593V datasheet, SLG5NT1593V pinout, SLG5NT1593V application, or SLG5NT1593V equivalent, key selection criteria include ultra-low quiescent current (0.02 μA off-state), fixed slew-rate control, STDFN 4L 1.0 × 1.0 mm package, and integrated 65–400 Ω discharge resistance for rapid output discharge.
Technical Context
The SLG5NT1593V implements a single P-channel MOSFET with gate drive logic tied to an active-high ON pin, enabling controlled turn-on with fixed slew-rate limiting to reduce inrush current. It operates without external components and supports input voltages from 1.5 V to 5.5 V.
Its internal discharge path activates automatically when the ON pin is deasserted, pulling VOUT to GND through a dedicated 65–400 Ω resistor. Thermal performance is specified up to 85 °C ambient, with 0.5 W maximum package power dissipation and safe operation area validated across VIN and IDS.
Key Specifications

|---|---|
| VIN Range | 1.5 V to 5.5 V - supports wide-input Li-ion, USB, and multi-rail systems |
| RDS(ON) @ 5.5 V | 28.5 mΩ typ - enables ≤28.5 mV drop at 1 A, minimizing conduction loss |
| IOUT Max | 1.0 A continuous - suitable for powering sensors, LEDs, or low-power peripherals |
| IQ (OFF) | 0.02 μA typ - preserves battery life in always-on standby modes |
| Discharge R | 65–400 Ω - ensures fast VOUT decay (<100 μs typical with 0.1 μF load) |
| Turn-on Delay | 12–76 μs - varies with VIN; enables predictable timing in power sequencing |
| Package | STDFN 4L, 1.0 × 1.0 × 0.55 mm - ultra-compact footprint for space-constrained PCBs |
Pinout & Package
SLG5NT1593V is housed in a 4-pin STDFN (Small Thin Dual Flat No-lead) package measuring 1.0 mm × 1.0 mm × 0.55 mm, with exposed thermal pad on bottom for enhanced heat dissipation.

FAQ
What is the maximum continuous current rating for the SLG5NT1593V?
The SLG5NT1593V is rated for 1.0 A continuous output current across its full operating temperature range of –40 °C to +85 °C. This rating is validated within the Safe Operating Area (SOA) curve shown in the datasheet, and derating applies above 85 °C ambient or with elevated PCB thermal resistance. The SLG5NT1593V maintains this rating while delivering 28.5 mΩ RDS(ON) at 5.5 V input.
Does the SLG5NT1593V require external components for basic operation?
No, the SLG5NT1593V operates autonomously with only VIN, VOUT, ON, and GND connections. It integrates fixed slew-rate control, discharge functionality, and bias circuitry-no external capacitors, resistors, or FETs are needed. The SLG5NT1593V is designed for plug-and-play deployment in compact power domains where minimal BOM count is essential.
What is the purpose of the integrated discharge resistor in the SLG5NT1593V?
The integrated 65–400 Ω discharge resistor in the SLG5NT1593V actively pulls VOUT to GND when the ON pin is deasserted, eliminating floating outputs and preventing unintended wake-up or latch-up in downstream circuits. This feature removes the need for external pull-down resistors, saving board space and ensuring reliable power-down behavior-especially critical in SLG5NT1593V-based battery-powered systems.
Can the SLG5NT1593V operate from a 1.5 V supply?
Yes, the SLG5NT1593V supports input voltages as low as 1.5 V, with verified RDS(ON) of 77.6 mΩ (typ) and total turn-on time of 292–399 μs at that rail. Its logic-compatible ON pin requires ≥0.85×VIN to activate, so at 1.5 V, ≥1.28 V is needed-compatible with standard GPIOs. This makes the SLG5NT1593V suitable for single-cell alkaline or NiMH systems where other load switches fail to operate.
What package type and dimensions does the SLG5NT1593V use?
The SLG5NT1593V uses a 4-pin STDFN (Small Thin Dual Flat No-lead) package measuring 1.0 mm × 1.0 mm × 0.55 mm with an exposed thermal pad. Its land pattern follows JEDEC MO-229 standards, and reflow must comply with IPC/JEDEC J-STD-020 for packages with 0.55 mm³ volume. This ultra-compact footprint is ideal for wearable and hearing aid-class PCBs where the SLG5NT1593V delivers full 1.0 A switching in minimal area.
