Product details
Overview
SLG59M1598V from Silego Technology (now part of Dialog Semiconductor) is a single-channel load switch IC with 17 mΩ RDS(ON), rated for 2.5 A continuous current, supporting input voltages from 0.85 V to 5 V. It integrates internal slew-rate control and thermal shutdown, and is used in portable power rail switching for battery-powered IoT sensors and wearables.
For engineers reviewing the SLG59M1598V datasheet, SLG59M1598V pinout, SLG59M1598V application, or SLG59M1598V equivalent, key selection criteria include its ultra-small 1 mm × 1.6 mm TDFN-8 package, low-voltage operation down to 0.85 V, integrated current-limiting capacitor terminal (CAP/ILIM), and absence of external enable resistor requirements.
Technical Context
The SLG59M1598V implements a MOSFET-based load switch with integrated gate driver and thermal protection logic. Its ON pin accepts CMOS-level control signals, and the CAP/ILIM pin sets both soft-start slew rate and overcurrent trip threshold via an external capacitor.
It operates without external bias components - no pull-up/pull-down resistors required on ON - and features bidirectional current sensing capability via dedicated D_Sense and S_Sense terminals, enabling precise RDS(ON) characterization during evaluation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 17 mΩ at VIN = 3.3 V, ILOAD = 2.5 A - enables low conduction loss in compact battery-powered systems |
| Input Voltage Range | 0.85 V to 5 V - supports direct connection to Li-ion, Li-Po, and regulated 1.2–3.3 V rails |
| Continuous Current | 2.5 A - sufficient for powering PMICs, RF modules, or sensor subsystems |
| Package | TDFN-8, 1 mm × 1.6 mm - ultra-compact footprint for space-constrained wearable PCBs |
| Thermal Shutdown | Integrated - automatically disables output above safe junction temperature, preventing damage during overload |
| Slew Rate Control | Via external capacitor on CAP/ILIM pin - reduces inrush current and EMI during power-up |
Pinout & Package
SLG59M1598V is housed in a Silego TDFN-8 package (1 mm × 1.6 mm, 0.4 mm pitch), with wettable flank leads for automated optical inspection. The package is RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Power supply input | Bias rail for internal circuitry; requires 0.1 µF decoupling capacitor placed adjacent to pin |
| ON (Pin 2) | Enable control input | CMOS-compatible active-high signal; no external pull-up needed |
| D/VIN (Pins 3,4) | Drain / Input voltage terminal | High-current input node; connected directly to power plane for minimal trace resistance |
| S/VOUT (Pins 5,6) | Source / Output voltage terminal | High-current output node; paired with D/VIN for low-inductance current path |
| CAP/ILIM (Pin 7) | Soft-start and current limit setting | Capacitor-connected pin that configures both turn-on slew rate and overcurrent threshold |
| GND (Pin 8) | Ground reference | Primary thermal and electrical return; must be connected to solid ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(ON) | 17 mΩ enables <10 mW conduction loss at 2.5 A - critical for extending battery life in always-on sensors |
| Sub-1 V operation | Functional down to 0.85 V input - supports direct connection to partially discharged Li-ion cells |
| Dedicated sense terminals | D_Sense and S_Sense pins allow Kelvin measurement of RDS(ON) without trace resistance error |
| No external enable resistors | ON pin has internal pull-down - eliminates BOM parts and layout area for basic enable functionality |
| Thermal foldback protection | Reduces output current before shutdown - maintains partial system operation during sustained overload |

Equivalent & Alternatives
The following parts are listed as comparable options for similar load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS22916BLYFPR | RDS(ON) = 22 mΩ at 3.3 V; fixed 1.2 ms slew rate; no sense terminals | Lacks D_Sense/S_Sense pins - unsuitable for production RDS(ON) validation | Preferred where board space permits larger 1.06 mm × 1.4 mm X2SON-6 package and sense capability is unnecessary |
| NIS5020MN | RDS(ON) = 28 mΩ at 3.3 V; requires external enable resistor; no thermal foldback | No integrated thermal foldback - shuts down completely on overtemperature | Acceptable for low-duty-cycle applications where full shutdown is acceptable and cost is primary constraint |
Compared with TPS22916BLYFPR and NIS5020MN, the SLG59M1598V uniquely combines sub-1 V operation, Kelvin sense capability, and thermal foldback in a 1 mm × 1.6 mm footprint - making it optimal for high-accuracy, battery-sensitive designs requiring in-system RDS(ON) verification.

FAQ
What is the minimum input voltage supported by SLG59M1598V?
The SLG59M1598V supports operation down to 0.85 V input voltage, verified per its datasheet and layout guide. This enables direct interface with deeply discharged lithium-based batteries. SLG59M1598V maintains specified RDS(ON) and enable timing across this range, unlike many competing load switches that require ≥1.2 V minimum.
Does SLG59M1598V require external pull-up or pull-down resistors on the ON pin?
No, SLG59M1598V includes an internal pull-down resistor on the ON pin, eliminating the need for external bias components. This simplifies schematic design and saves PCB area. SLG59M1598V's ON pin is CMOS-compatible and responds to standard logic-high signals without additional circuitry.
How is current limiting configured on SLG59M1598V?
Current limiting on SLG59M1598V is set via an external capacitor connected to the CAP/ILIM pin (Pin 7). Capacitor value determines both soft-start slew rate and overcurrent trip threshold. SLG59M1598V does not use adjustable resistors or digital interfaces for current limit configuration - only passive capacitor selection is required.
Can SLG59M1598V be used for bidirectional current sensing?
SLG59M1598V provides dedicated D_Sense and S_Sense terminals for Kelvin-style RDS(ON) measurement, but it is not a bidirectional current sensor IC. These pins support accurate forward-path resistance characterization only - SLG59M1598V does not measure reverse current or provide analog current output.
What thermal protection features does SLG59M1598V include?
SLG59M1598V integrates thermal shutdown and thermal foldback protection. When junction temperature exceeds safe limits, SLG59M1598V first reduces output current (foldback) to sustain partial operation; if temperature continues rising, it fully disables the output. Both behaviors are internally managed without external components.
