Product details
Overview
SLG5NT1487V from Silego Technology is a single-channel load switch IC designed to control 2.5–5.5 V power rails with 7.8 mΩ RDS(ON), 5 A continuous current capability, user-configurable slew rate via external capacitor, integrated discharge path, and dual-mode overcurrent protection. It serves as a precision power rail switch in portable computing and mobile devices.
For engineers reviewing the SLG5NT1487V datasheet, SLG5NT1487V pinout, SLG5NT1487V application, or SLG5NT1487V equivalent, key selection criteria include its ultra-small 1.5 × 2.0 mm FC-TDFN package, logic-level ON input (VIH ≥ 0.85 V), thermal shutdown at 125 °C, active current limit of 7.0 A, and short-circuit current limit of 500 mA.
Technical Context
The SLG5NT1487V integrates a high-side N-channel MOSFET with charge-pump gate drive, enabling operation from 2.5 V VDD. Its linear ramp control uses an external capacitor on CAP pin to set turn-on slew rate and total rise time independently of load capacitance.
It implements two distinct overcurrent protection modes: active current limiting (7.0 A) above 250 mV source voltage, and short-circuit limiting (500 mA) below 250 mV - automatically switching between them based on sensed VS. Thermal protection disables the MOSFET at 125 °C and re-enables at 100 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 7.8 mΩ typical at 25 °C - enables low conduction loss for 5 A loads, minimizing voltage drop and self-heating |
| Continuous Current | 5 A - supports high-current power rail switching without external heatsinking in compact designs |
| Input Voltage Range | 2.5 V to 5.5 V on VDD - compatible with common logic-supply domains including 3.3 V and 5 V systems |
| ON Pin Logic Threshold | VIH ≥ 0.85 V - ensures reliable activation from standard 1.8 V or 3.3 V GPIOs without level-shifting |
| Discharge Resistance | 100–300 Ω - actively discharges output when OFF, preventing floating or unintended wake-up of downstream circuitry |
| Thermal Shutdown | 125 °C turn-off / 100 °C turn-on hysteresis - provides robust fault recovery under sustained overload or poor PCB thermal design |
| Turn-On Delay | 0–500 μs - allows precise sequencing control between VDD, ON signal, and input voltage ramp |
Pinout & Package
SLG5NT1487V is housed in an ultra-compact 1.5 × 2.0 mm FC-TDFN 8L package with fused drain (pins 3 & 4) and fused source (pins 5 & 6) terminals to support high-current routing in minimal board area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Power supply input | Provides bias for internal charge pump and control logic; must be stable ≥1 V before applying VD |
| 2 - ON | Logic enable input | CMOS-compatible control pin with 4 MΩ internal pull-down; asserts high to activate MOSFET |
| 3 & 4 - D | Drain terminal (fused) | High-current input node connected to upstream power rail; pins electrically and thermally paralleled |
| 5 & 6 - S | Source terminal (fused) | High-current output node driving load; fused layout reduces resistance and improves thermal spreading |
| 7 - CAP | Ramp rate configuration | External capacitor sets linear slew rate and total turn-on time; values from 100 pF to 16 nF supported |
| 8 - GND | Ground reference | Common return for control circuitry and MOSFET body; requires low-impedance connection to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| User-configurable slew rate | Linear ramp control via external capacitor on CAP pin enables EMI-optimized power sequencing without RC timing uncertainty |
| Dual-mode overcurrent protection | Switches automatically between 7.0 A active limit (for overload) and 500 mA short-circuit limit (for solder bridges or hard shorts) |
| Integrated discharge path | 150 Ω typical RDIS actively pulls VS to GND when OFF, eliminating need for external bleed resistor and reducing BOM count |
| Ultra-small footprint | 1.5 × 2.0 mm FC-TDFN package with fused leads delivers 5 A capability in <3 mm² board area - ideal for space-constrained mobile PCBs |
| Thermal fault recovery | Hysteresis-based thermal shutdown (125 °C off / 100 °C on) enables self-resetting protection during transient overloads without system reset |

Equivalent & Alternatives
The following parts are listed as comparable options for similar load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS22965DSGR | Higher RDS(ON) (12 mΩ), fixed 1.2 ms slew rate, no short-circuit current limit mode | Lacks dual-mode OCP; suitable only where hard shorts are ruled out by design or test | Choose if board space allows larger 2 × 2 mm package and fixed ramp suffices for EMI control |
| NIS5132MN | Higher RDS(ON) (15 mΩ), no discharge function, thermal shutdown at 150 °C (no hysteresis) | Requires external discharge resistor; less robust under sustained overload due to non-hysteretic thermal shutdown | Prefer only when cost sensitivity outweighs need for active discharge and thermal recovery behavior |
Compared with TPS22965DSGR and NIS5132MN, the SLG5NT1487V offers lower conduction loss, user-tunable slew rate, integrated discharge, and hysteresis-based thermal protection - making it optimal for space-constrained, high-reliability portable power systems requiring precise sequencing and robust fault handling.

FAQ
What is the maximum continuous current rating for the SLG5NT1487V?
The SLG5NT1487V supports 5 A continuous current at ambient temperatures up to 70 °C with proper PCB copper pour. Its 7.8 mΩ RDS(ON) minimizes power dissipation, and thermal protection activates at 125 °C to prevent damage during overload conditions. The SLG5NT1487V maintains this rating across its full 2.5–5.5 V input range when used within specified layout guidelines.
How does the SLG5NT1487V implement dual-mode overcurrent protection?
The SLG5NT1487V monitors source voltage (VS) to distinguish fault types: above 250 mV, it applies active current limiting at 7.0 A; below 250 mV, it switches to short-circuit limiting at 500 mA. This dual-mode behavior is implemented via an internal current mirror with selectable gain, enabling robust response to both overload and hard-short faults without external components. The SLG5NT1487V handles both scenarios autonomously.
Can the SLG5NT1487V be used with a 1.8 V logic ON signal?
Yes - the SLG5NT1487V specifies VIH ≥ 0.85 V, making it fully compatible with 1.8 V CMOS logic. Its 4 MΩ internal pull-down ensures reliable OFF-state default, and the ON pin draws negligible current. No level shifter is needed, simplifying interface design. The SLG5NT1487V retains full functionality including slew control and protection features when driven directly from 1.8 V GPIOs.
What is the role of the CAP pin on the SLG5NT1487V?
The CAP pin on the SLG5NT1487V connects to an external capacitor that sets both total turn-on time and slew rate in a linear, predictable manner - independent of load capacitance. Capacitor values from 100 pF to 16 nF adjust TTOTAL_ON from ~0.3 ms to >6 ms and slew rate from ~15 V/ms to ~1 V/ms. This eliminates RC timing uncertainty and enables repeatable EMI optimization. The SLG5NT1487V relies solely on this capacitor for ramp control.
Does the SLG5NT1487V provide active discharge when turned OFF?
Yes - the SLG5NT1487V integrates a 100–300 Ω discharge path between source (S) and ground (GND) that activates automatically when the ON pin is deasserted. This eliminates residual voltage on downstream capacitors, prevents unintended wake-up of powered-off circuitry, and removes the need for external bleed resistors. The SLG5NT1487V achieves full discharge without additional components or control signals.
