Product details
Overview
SI1867DL-T1-E3 from Vishay Siliconix is a dual-MOSFET load switch IC integrating a p-channel TrenchFET (RDS(on) = 0.600 Ω at VIN = 4.5 V) and an n-channel MOSFET for level-shift control, operating from 1.8 V to 8 V input, supporting ±0.6 A continuous load current, and housed in SC70-6 package - used for high-side load switching in space-constrained portable electronics.
For engineers reviewing the SI1867DL-T1-E3 datasheet, SI1867DL-T1-E3 pinout, SI1867DL-T1-E3 application, or SI1867DL-T1-E3 equivalent, key selection considerations include its logic-level compatibility down to 1.5 V, externally adjustable slew rate via R2/C1, integrated ESD protection (2 kV HBM), and thermal resistance (RthJA = 320 °C/W) for low-power battery-operated systems.
Technical Context
The SI1867DL-T1-E3 implements a high-side load switch architecture where the p-channel MOSFET handles main power path conduction while the n-channel MOSFET acts as a gate driver with level-shift capability - enabling direct interface with low-voltage logic (≥1.5 V). Its dual-FET integration eliminates discrete level-shifter components.
Switching behavior is externally programmable: rise/fall times are set by optional R2 (0–100 kΩ) and C1 (1000 pF), allowing tailoring of inrush current for diverse capacitive loads. The device supports operation across -55 °C to +150 °C junction temperature range with guaranteed performance at 25 °C and derated limits at extremes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.8 V to 8 V - enables use across single-cell Li-ion (2.7–4.2 V), 3.3 V, and 5 V rails without external regulators. |
| P-Channel RDS(on) | 0.600 Ω at VIN = 4.5 V, ID = 0.6 A - limits voltage drop to ≤360 mV at full rated load, minimizing power loss and heat generation. |
| Logic Control Threshold | 1.5 V to 8 V - ensures reliable turn-on with 1.8 V GPIOs and compatibility with 3.3 V/5 V controllers without level translators. |
| Continuous Load Current | ±0.6 A - supports moderate-power peripherals like displays, sensors, or USB ports in portable devices. |
| Thermal Resistance | RthJA = 320 °C/W - defines maximum power dissipation (0.4 W) under standard FR4 PCB conditions; requires careful layout for sustained loads. |
| ESD Rating | 2 kV HBM - provides basic handling robustness during assembly but not system-level ESD immunity; external protection may be needed. |
Pinout & Package
SC70-6 package: ultra-small surface-mount outline (2.0 mm × 1.25 mm × 0.95 mm height), lead (Pb)-free, RoHS-compliant, halogen-free per IEC 61249-2-21.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VIN | Main input supply rail connection for load switch; feeds both p-channel source and n-channel drain. |
| 2, 3 | GND | Common ground reference for logic control and power return; pins 2 and 3 are internally bonded for lower inductance. |
| 4 | VOUT | Switched output node - connects to load; p-channel drain terminal with integrated body diode cathode. |
| 5 | ON/OFF | Logic-level enable input; drives n-channel gate to control p-channel turn-on via internal level-shift path. |
| 6 | S | Source of p-channel MOSFET - tied internally to VIN; not externally accessible as separate terminal. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated p+n Dual MOSFET | Eliminates need for external level-shifter transistor and pull-up resistor, reducing BOM count and PCB area in portable designs. |
| Adjustable Slew Rate | Controlled via external R2 (0–100 kΩ) and C1 (1000 pF) to limit inrush current and prevent supply droop on sensitive rails. |
| TrenchFET® Technology | Delivers low RDS(on) at low VGS, enabling efficient switching even at 1.8 V input with minimal conduction loss. |
| Logic-Compatible Gate Drive | N-channel MOSFET accepts 1.5 V minimum logic high, ensuring interoperability with modern ultra-low-voltage microcontrollers and PMICs. |
Applications

IC Role / Device Role / Timing Role: Low-leakage (1 µA max reverse current) power gate between main LDO and sensor rail; controlled by MCU wake-up interrupt. Use Value: Enables sub-µA system sleep states; 1.5 V logic compatibility allows direct interface with 1.8 V MCU I/O without level shifters. |
| USB-C Accessory Detection | Portable Medical Monitor |
Use Scenario: Powering USB enumeration circuitry only when cable insertion is detected, avoiding standby current draw.

Equivalent & Alternatives
The following parts are listed as comparable options for similar load-switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS22965DSGT | Single-channel, 0.57 Ω RDS(on) at 3.3 V, fixed internal slew rate, no level-shift n-FET - requires external logic-level compatible control. | Lacks integrated level-shift; suitable only when host MCU outputs ≥2.5 V logic high; smaller 1.0 mm × 1.5 mm DSG package. | Select if board space is more constrained than logic-voltage flexibility, and external level translation is already present. |
| AP22653AW5-7 | Single-channel, 0.65 Ω RDS(on) at 5 V, 1.2 V min logic threshold, integrated soft-start (fixed 1.2 ms), no n-FET - simpler control but less adjustable. | Fixed soft-start replaces R2/C1 tuning; better for plug-and-play use; 1.2 V logic support extends to newer ultra-low-voltage SoCs. | Prefer when deterministic turn-on timing is required and design lacks space or need for external slew components. |
Compared with TPS22965DSGT and AP22653AW5-7, the SI1867DL-T1-E3 uniquely combines dual-FET integration with externally adjustable slew control and 1.5 V logic compatibility - making it optimal for compact, multi-rail portable systems requiring fine-grained inrush management and legacy logic interfacing.

FAQ
What is the maximum continuous load current supported by the SI1867DL-T1-E3?
The SI1867DL-T1-E3 supports ±0.6 A continuous load current at TA = 25 °C with proper PCB thermal relief. Derating applies above 25 °C ambient: at 85 °C, maximum continuous current drops to approximately ±0.35 A due to thermal limitations (RthJA = 320 °C/W, PD = 0.4 W max). The SI1867DL-T1-E3 must be used within Safe Operating Area boundaries shown in the datasheet.
Can the SI1867DL-T1-E3 operate with a 1.8 V logic control signal?
Yes, the SI1867DL-T1-E3 accepts logic-level control signals as low as 1.5 V, fully supporting 1.8 V GPIOs without external level shifting. Its n-channel MOSFET is designed for reliable turn-on at VON/OFF ≥ 1.5 V, and the datasheet confirms functional operation down to 1.5 V at all input voltages (1.8–8 V). This makes the SI1867DL-T1-E3 suitable for direct interface with modern ultra-low-voltage MCUs.
How is slew rate controlled on the SI1867DL-T1-E3?
Slew rate on the SI1867DL-T1-E3 is controlled externally using resistor R2 (connected between ON/OFF and GND) and optional capacitor C1 (1000 pF, between ON/OFF and GND). Typical R2 values range from 0 to 100 kΩ; increasing R2 lengthens rise/fall times. The SI1867DL-T1-E3 datasheet provides switching variation curves for R2 at multiple VIN and R1 combinations to guide selection.
What package type and dimensions does the SI1867DL-T1-E3 use?
The SI1867DL-T1-E3 uses the SC70-6 surface-mount package: 2.0 mm × 1.25 mm footprint, 0.95 mm maximum height, with gull-wing leads. It is lead (Pb)-free and RoHS-compliant, marked with "VB" top-side code and lot traceability. The SI1867DL-T1-E3's compact size targets high-density portable PCBs where space is at a premium.
Does the SI1867DL-T1-E3 include ESD protection?
Yes, the SI1867DL-T1-E3 includes internal ESD protection on the n-channel MOSFET gate, rated at 2 kV per MIL-STD-833D Human Body Model. This protects against typical handling ESD events but does not replace system-level ESD protection for I/O lines exposed to user interfaces. The SI1867DL-T1-E3's ESD rating is specified and verified per standard test conditions in the official Vishay datasheet (Doc. #72534).
