Product details
Overview
SLG5NT1477V from Renesas Electronics is a single-channel nanopower load switch IC with 9.8 mΩ RDS(ON) at 3.0 V VDD–VD, rated for 6 A continuous drain current, supporting 0.85 V to 3.3 V output rails, and featuring integrated discharge functionality. It operates across -40 °C to +85 °C and targets mobile power rail switching in space-constrained devices.
For engineers reviewing the SLG5NT1477V datasheet, SLG5NT1477V pinout, SLG5NT1477V application, or SLG5NT1477V equivalent, this page delivers verified specifications, validated pin functions, confirmed thermal and electrical behavior under load, and real-world design context for smartphone, tablet, and wearable power sequencing.
Technical Context
The SLG5NT1477V integrates a low-RDS(ON) N-channel MOSFET with internal gate driver, logic-level ON control (0.85 V VIH), and active discharge path via 180 Ω internal resistor. Its fast turn-on time (7–12 µs) and controlled slew rate (20–190 V/ms) enable precise inrush current management for capacitive loads up to 10 µF.
It uses a fused-pin FC-TDFN 9L package (1.5 × 2.0 mm) with three drain pins (pins 2,3,4), three source pins (pins 5,6,7), dedicated VDD (pin 1), GND (pin 8), and CMOS-compatible ON input (pin 9) with 4 MΩ internal pull-down. Thermal performance is optimized via exposed pad and wide copper traces per layout guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Continuous Current | 6 A - supports high-current subsystems like display or camera modules |
| Input Voltage Range | 3.0 V to 5.25 V on VDD - powers internal circuitry from main system rail |
| Output Rail Range | 0.85 V to (VDD – 1.5 V) - compatible with core voltages of modern SoCs and PMICs |
| Discharge Resistance | 180 Ω typical - actively discharges load capacitance when OFF, preventing floating voltage |
| Quiescent Current | 30 nA typical OFF-state IDD - preserves battery life in always-on mobile standby modes |

Pinout & Package
SLG5NT1477V is housed in a 1.5 × 2.0 mm FC-TDFN 9L package with fused drain and source pins and an exposed thermal pad. Pin 1 is marked by a dot; top view orientation follows JEDEC MO-252 W2015D standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Power supply input | Provides 3.0–5.25 V bias for internal control circuitry; requires local 0.1 µF + 10 µF decoupling |
| 2,3,4 - D | Drain terminals | Fused pins carrying full load current from input rail to internal MOSFET; connect directly to VIN |
| 5,6,7 - S | Source terminals | Fused pins delivering switched output (VOUT); connect to load and discharge path; require wide PCB traces |
| 8 - GND | Ground reference | System ground return for control logic and thermal path; must connect to solid ground plane |
| 9 - ON | CMOS enable input | Active-high logic input with 0.85 V VIH threshold; internal 4 MΩ pull-down ensures default OFF state |
Key Features
| Feature | Design Value |
|---|---|
| Nanopower operation | 30 nA typical quiescent current in OFF state - extends battery runtime in always-off subsystems |
| Integrated discharge | 180 Ω internal RDISCHRG - eliminates need for external discharge FET or resistor network |
| Ultra-small footprint | 1.5 × 2.0 mm FC-TDFN 9L - saves >50% board area vs. comparable 2 mm × 2 mm load switches |
| Logic-level compatibility | 0.85 V VIH threshold - interfaces directly with 0.9 V/1.2 V I/O domains of modern APs and MCUs |
| Controlled slew rate | 20–190 V/ms output ramp - prevents LDO overcurrent tripping and reduces EMI during power-up |
| Thermal robustness | Exposed pad + fused power pins - supports 6 A continuous current with minimal temperature rise in 2 oz copper layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS22916BLYFPR | 4.7 mΩ RDS(ON) at 5 V, 1.06 mm × 0.66 mm DSBGA, no integrated discharge | Lacks discharge path; requires external resistor/FET for load discharge | Preferred where ultra-low RDS(ON) and smallest footprint outweigh discharge requirement |
| AP22653AW5-7 | 12 mΩ RDS(ON) at 5 V, 1.2 mm × 1.2 mm TSOT-23-5, 4.5 A rating, integrated discharge | Lower current rating and higher RDS(ON); smaller package but no fused pins for high-current routing | Suitable for ≤4.5 A applications where board space is more constrained than thermal budget |
Compared with TPS22916BLYFPR and AP22653AW5-7, SLG5NT1477V uniquely balances 6 A capability, 9.8 mΩ conduction loss, integrated 180 Ω discharge, and fused-pin thermal design in a 1.5 × 2.0 mm FC-TDFN - making it optimal for thermally demanding mobile subsystems requiring both high current and clean shutdown.

FAQ
What is the maximum continuous current rating for SLG5NT1477V?
The SLG5NT1477V is rated for 6 A continuous drain current under specified thermal conditions (TA = -40 °C to +85 °C, proper PCB layout with 2 oz copper). This rating assumes adequate heat dissipation via the exposed pad and fused source/drain pins. At 6 A and 9.8 mΩ RDS(ON), power dissipation is ~350 mW - well within the 1.0 W package power limit when implemented per Renesas layout guidelines.
Does SLG5NT1477V support 0.85 V logic-level inputs?
Yes, SLG5NT1477V features a logic-level ON pin with VIH ≥ 0.85 V and VIL ≤ 0.2 V, enabling direct interface with 0.9 V I/O domains common in modern application processors and microcontrollers. The internal 4 MΩ pull-down resistor ensures a defined OFF state when the ON pin is left floating or driven low.
How does the integrated discharge function work in SLG5NT1477V?
When the ON pin is driven low, SLG5NT1477V disables the main MOSFET and activates an internal 180 Ω discharge path between the S (source) terminal and GND. This safely bleeds stored charge from load capacitance, preventing floating voltages that could cause latch-up or false wake events. The discharge time constant depends on load capacitance - e.g., 10 µF discharges to <10% in ~4.2 ms.
What package type and dimensions does SLG5NT1477V use?
SLG5NT1477V uses a 9-lead FC-TDFN package measuring 1.5 mm × 2.0 mm × 0.75 mm (JEDEC MO-252 W2015D), with fused drain (pins 2,3,4) and source (pins 5,6,7) terminals for low-inductance, high-current routing. The exposed thermal pad enhances heat transfer to the PCB, and the top marking includes "JZA" part code and date/revision codes.
Can SLG5NT1477V drive capacitive loads larger than 10 µF?
Capacitive loads exceeding 10 µF directly on the S pin may cause nonlinear output ramping and excessive inrush current. For >10 µF loads, Renesas recommends using a 2.2 µH inductor in series with the load and placing a 1 µF capacitor at the S pin - as shown in the Application Diagram - to maintain linear slew rate control and ensure reliable inrush limiting. SLG5NT1477V itself supports up to 10 µF directly.
