Product details
Overview
SLG59H1017V from Renesas Electronics is a high-voltage NMOS load switch optimized for 12 V or 24 V point-of-load power distribution, delivering 4 A continuous current with 13.3 mΩ RDSON at 24 V, pin-selectable VIN lockout thresholds, and an analog 10 µA/A MOSFET current monitor output. It integrates automatic SOA protection, two-stage current limiting, and fast 4 kΩ output discharge for industrial power-rail switching.
For engineers reviewing the SLG59H1017V datasheet, SLG59H1017V pinout, SLG59H1017V application, or SLG59H1017V equivalent, key selection criteria include its dual-voltage lockout select (SEL), resistor-adjustable active current limit (RSET), thermal shutdown at 145 °C, and STQFN 18-pin 1.6 × 3.0 mm package with fused VIN/VOUT power pins.
Technical Context
The SLG59H1017V implements a proprietary high-voltage GreenFET architecture with copper pillar interconnects to maintain stable RDSON (< 0.05 mΩ/V vs. VIN, < 0.06 mΩ/°C vs. temperature) across -40 °C to 85 °C. Its state machine manages linear ramp control, CL/SC detection, and over-temperature protection with automatic 160 ms retry after SOA shutdown.
It features dual-mode protection: resistor-adjustable active current limit (3.19 A typical at RSET = 30.1 kΩ) and internal short-circuit limit (~0.5 A), plus 10 W SOA foldback that reduces to 5 W after trigger and resets only upon ON pin toggle. The FAULT pin asserts within 80 µs on fault events and de-asserts within 180 µs after clearance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Current | 4 A - supports high-current 12 V/24 V rails without external heatsinking in standard PCB layouts |
| RDSON | 13.3 mΩ at 24 V - enables < 100 mV drop at 4 A, minimizing conduction loss and self-heating |
| VIN Lockout Select | Pin-configurable: SEL = LOW → 12 V ±10% UVLO/OVLO; SEL = HIGH → 24 V ±5% UVLO/OVLO |
| IOUT Monitor | 10 µA/A analog output - provides real-time current sensing with 0.5–4 A linear range into RIOUT |
| Thermal Protection | Shuts down at 145 °C, restarts at 125 °C - prevents permanent damage during sustained overload |
| Package | STQFN 18L, 1.6 × 3.0 mm, 0.4 mm pitch - low θJA = 40 °C/W enables high-power operation on compact boards |
| SOA Threshold | 10 W internal power dissipation limit - triggers automatic FET turn-off before thermal runaway |
Pinout & Package
SLG59H1017V is housed in a RoHS-compliant, low-thermal-resistance 18-pin STQFN package (1.6 × 3.0 mm, 0.40 mm pitch), featuring fused multi-pin VIN (pins 4–8) and VOUT (pins 9–13) terminals for high-current routing and minimal trace resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ON (Pin 1) | CMOS enable input | Level-sensitive control: HIGH > 0.9 V initiates soft-start; requires external GPO drive-no internal pull-down |
| GND (Pins 2, 3) | Ground reference | Pin 2: low-current logic ground; Pin 3: main power/charge-pump ground-must connect directly to system plane |
| VIN (Pins 4–8) | Power input terminal | Fused drain connection for nFET; requires ≥47 µF/50 V capacitor to minimize voltage droop and EMI |
| VOUT (Pins 9–13) | Power output terminal | Fused source connection; supports high-current loads with low-inductance path to CLOAD |
| SEL (Pin 14) | VIN lockout mode select | Configures UVLO/OVLO windows: LOW = 12 V system (9.7–14.5 V), HIGH = 24 V system (19.5–28.5 V) |
| FAULT (Pin 15) | Open-drain fault indicator | Asserts LOW within 80 µs on UVLO/OVLO/current/thermal fault; requires 100 kΩ pull-up to local logic supply |
| CAP (Pin 16) | Slew rate timing node | Connects to 10–20 nF ceramic capacitor to set VOUT rise time (2.7–3.9 V/ms typical) |
| IOUT (Pin 17) | Analog current monitor | 10 µA/A output; 0.5–4 V compliance range; bypass with 180 pF for optimal linearity and bandwidth |
| RSET (Pin 18) | Active current limit set | 20–91 kΩ resistor sets IACL from 4.5 A down to 1 A (±15% accuracy over temp/voltage) |
Key Features
| Feature | Design Value |
|---|---|
| Stable RDSON vs. VIN/temp | ΔRDSON/ΔVIN < 0.05 mΩ/V and ΔRDSON/ΔT < 0.06 mΩ/°C - ensures predictable voltage drop across full operating range |
| Two-stage current protection | Resistor-adjustable active limit (1–4.5 A) + fixed short-circuit limit (~0.5 A) - prevents latch-up while maintaining system responsiveness |
| Capacitor-adjustable slew rate | CSLEW = 10–20 nF sets monotonic VOUT ramp (2.7–3.9 V/ms) - avoids non-monotonic start-up and SOA false triggers |
| Integrated SOA protection | 10 W instantaneous power threshold with 160 ms auto-retry and 5 W foldback - survives short circuits without manual reset |
| Fast output discharge | 4.4 kΩ internal discharge path - clears VOUT within microseconds after OFF, preventing backfeed or residual charge |

Equivalent & Alternatives
The following parts are listed as comparable options for similar load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS22992DRLR | 4.5 V–13.2 V input, 4 A, 19 mΩ RDSON, no VIN lockout select or IOUT monitor | Designed for lower-voltage systems only; lacks analog current monitoring and dual-voltage lockout | Choose when operating strictly below 13.2 V and telemetry is not required; smaller 1.0 × 1.5 mm package |
| RTQ2134BGQW | 2.7 V–28 V input, 4 A, 15 mΩ RDSON, 10 µA/A IOUT, but no SEL-based lockout window selection | Supports wider VIN range but uses fixed 2.7 V UVLO and 28 V OVLO-no 12 V/24 V mode toggle | Prefer when wide-input flexibility matters more than precise lockout window tuning; includes thermal foldback |
Compared with TPS22992DRLR and RTQ2134BGQW, the SLG59H1017V uniquely combines pin-selectable 12 V/24 V lockout windows, ultra-low 13.3 mΩ RDSON, and integrated SOA protection-making it optimal for high-reliability industrial power distribution where voltage tolerance and fault resilience are critical.

FAQ
What is the maximum continuous current rating for the SLG59H1017V?
The SLG59H1017V supports a maximum continuous current of 4 A under TJ < 150 °C conditions. This rating assumes proper PCB layout with adequate copper area and thermal vias, as specified in the datasheet's layout guidelines. At 85 °C ambient and 24 V input, RDSON rises to 19 mΩ, resulting in ~304 mW conduction loss-well within the device's 10 W SOA limit when combined with appropriate heat sinking.
How does the SEL pin configure VIN lockout thresholds on the SLG59H1017V?
The SEL pin on the SLG59H1017V selects between two VIN lockout windows: when pulled LOW (≤0.3 V), it configures 12 V ±10% operation (UVLO = 9.7–10.7 V, OVLO = 13.3–14.5 V); when pulled HIGH (≥1.65 V), it configures 24 V ±5% operation (UVLO = 19.5–21.5 V, OVLO = 25.3–28.5 V). This eliminates external resistor networks and enables one hardware design to serve dual-voltage platforms.
What is the function and accuracy of the IOUT pin on the SLG59H1017V?
The IOUT pin on the SLG59H1017V delivers an analog current proportional to load current at 10 µA/A (±7% typical, ±10% max over temperature and voltage). With 0.5–4 V compliance range and optimal linearity from 0.5 A to 4 A, it enables precise current telemetry using a simple ground-referenced resistor (e.g., 84.5 kΩ yields 0.845 V/A). A 180 pF capacitor is recommended for stability.
Does the SLG59H1017V require external components for basic operation?
Yes-the SLG59H1017V requires external components for safe, functional operation: a ≥47 µF/50 V capacitor on VIN, a ≥47 µF/50 V capacitor on VOUT, a 10–20 nF ceramic capacitor on CAP for slew control, a 20–91 kΩ resistor on RSET for current limiting, and a 100 kΩ pull-up on FAULT. The ON and SEL pins must be actively driven-no internal pull resistors are present.
How does SOA protection operate on the SLG59H1017V during overload conditions?
SLG59H1017V SOA protection triggers when internal power dissipation exceeds 10 W, causing immediate FET turn-off. After a 160 ms cooldown, it attempts auto-restart at reduced 5 W SOA limit. Full 10 W operation resumes only after toggling the ON pin LOW then HIGH. This foldback behavior prevents thermal runaway during sustained shorts while enabling graceful recovery without system intervention.
