Product details
Overview
SIP4610BDT-T1-E3 from Vishay Siliconix is an active-high enable, protected 1-A high-side load switch in a thin SOT-23-5 package. It operates from 2.4 V to 5.5 V, features user-settable current limiting (0.75–1.25 A with RSET), undervoltage lockout (1.8–2.4 V), and thermal shutdown at 165 °C. It serves as a smart power rail controller for peripheral port protection in notebook computers and hot-swap subsystems.
For engineers reviewing the SIP4610BDT-T1-E3 datasheet, SIP4610BDT-T1-E3 pinout, SIP4610BDT-T1-E3 application, or SIP4610BDT-T1-E3 equivalent, key selection criteria include enable polarity (active-high), RSET-based current limit configuration, thermal shutdown hysteresis (20 °C), quiescent current (9 µA), and SOT-23-5 footprint compatibility with space-constrained portable designs.
Technical Context
The SIP4610BDT-T1-E3 integrates a PMOS pass transistor with internal current-sense amplifier, comparator, reference voltage (VREF), and thermal shutdown circuitry. Its current-limit function relies on external RSET to set threshold via VSET = ILIMIT × RSET, compared against 0.5 V internal reference.
It implements active-high ON/ON control logic (distinct from SIP4610ADT-T1-E3's active-low), undervoltage lockout with 0.05 V hysteresis, and thermal cycling behavior (shutdown at 165 °C, restart at 145 °C). Power dissipation is limited to 305 mW at TA = 70 °C due to θJA = 180 °C/W in thin SOT-23-5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 1 A - supports stable power delivery to USB peripherals or card readers without thermal runaway. |
| Supply Voltage Range | 2.4 V to 5.5 V - compatible with single-cell Li-ion (3.0–3.6 V), 3.3 V, and 5 V system rails. |
| On-Resistance (rDS(on)) | 145–180 mΩ at 5 V - limits conduction loss to ≤180 mV drop at 1 A, reducing self-heating. |
| Quiescent Current | 9 µA - enables ultra-low standby power in battery-powered systems like PDAs. |
| Current Limit Accuracy | ±25 % - requires 33 % design headroom (ILOAD × 1.33) when selecting RSET. |
| Thermal Shutdown Threshold | 165 °C - protects die during sustained overload; 20 °C hysteresis prevents oscillation near trip point. |
| ESD Rating (HBM) | 4 kV - meets IEC 61000-4-2 Level 3 for robustness in handheld device interfaces. |
Pinout & Package
Package: Thin SOT-23-5, RoHS-compliant, rated for -40 °C to +85 °C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Switch output node | Connects to load; voltage follows IN when enabled, floats high-impedance when off. |
| 2 - GND | Power ground reference | Return path for internal bias, current sense, and thermal sensor; must be low-impedance PCB connection. |
| 3 - SET | Current limit programming input | Accepts resistor-to-GND to set ILIMIT; VSET = ILIMIT × RSET compared to 0.5 V internal reference. |
| 4 - ON/ON | Active-high enable input | Drives internal gate driver when ≥2.0 V (VIH); disables switch when ≤0.8 V (VIL); distinguishes SIP4610B from SIP4610A. |
| 5 - IN | Input supply and switch source | Primary power input; supplies internal circuitry and provides source for PMOS pass device. |
Key Features
| Feature | Design Value |
|---|---|
| User-configurable current limit | RSET-based threshold (e.g., 6.8 kΩ → 1 A) enables precise load protection without redesigning IC-level logic. |
| Active-high enable interface | Eliminates need for external inverter when controlled by microcontroller GPIOs asserting high to activate power rail. |
| Low quiescent current (9 µA) | Reduces battery drain in always-on subsystems such as wake-on-LAN or real-time clock backup circuits. |
| Integrated UVLO with hysteresis | Prevents erratic switching during brown-out conditions; 0.05 V hysteresis ensures clean re-enable after recovery. |
| Thermal shutdown with 20 °C hysteresis | Enables autonomous recovery from temporary overloads without host intervention or firmware polling. |
Applications
| USB Peripheral Port Protection | Notebook ExpressCard Slot |
|---|---|

IC Role / Device Role / Timing Role: Low-quiescent-current (9 µA) high-side switch enabling deep-sleep mode while retaining ability to rapidly enable card power on demand. Use Value: Extends battery runtime by minimizing standby leakage, while RSET tuning allows matching exact card peak current requirements (e.g., 800 mA). | Use Scenario: Protecting 3.3 V backplane slots in modular industrial controllers subject to field-replaceable module insertion under power. IC Role / Device Role / Timing Role: Robust hot-swap controller with 4 kV HBM ESD rating and thermal cycling tolerance for repeated live-insertion cycles. Use Value: Eliminates need for external TVS diodes or current-sense amplifiers, reducing BOM count and improving long-term reliability in dusty, high-vibration environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP22653AW5-7 | Active-high enable, 2.5–5.5 V range, fixed 1.5 A current limit, 110 mΩ rDS(on), no RSET adjustability | Requires no external resistor but lacks fine-tuned current threshold; better for cost-sensitive designs with fixed load profiles | Select when simplicity and lower on-resistance outweigh need for adjustable current limiting. |
| TPS22965DSGR | Active-high enable, 0.8–5.5 V range, 2 A continuous, 34 mΩ rDS(on), integrated quick-output-discharge (QOD) | Supports wider VIN range and higher current, includes QOD for faster load discharge-critical in multi-rail sequencing | Choose for high-current, low-drop applications requiring rapid turn-off discharge and broader input flexibility. |
Compared with AP22653AW5-7 and TPS22965DSGR, the SIP4610BDT-T1-E3 offers unique RSET-based current limit adjustability within a 2.4–5.5 V window and industry-standard SOT-23-5 footprint, making it optimal for portable designs needing precise, low-power, thermally robust load control without added complexity.

FAQ
What is the enable polarity of SIP4610BDT-T1-E3?
The SIP4610BDT-T1-E3 features an active-high enable input (ON/ON pin). When the voltage on pin 4 exceeds 2.0 V (VIH), the internal PMOS switch turns on; below 0.8 V (VIL), it shuts off. This distinguishes it from the SIP4610ADT-T1-E3, which uses active-low enable logic. The SIP4610BDT-T1-E3 simplifies interface with microcontrollers lacking open-drain outputs.
How do I configure the current limit for SIP4610BDT-T1-E3?
Configure the current limit for SIP4610BDT-T1-E3 by connecting a resistor (RSET) between pin 3 (SET) and GND. For a 1 A limit, use 6.8 kΩ (RSET coefficient = 7100). The actual limit is IL = 7100 / RSET (kΩ), with ±25 % tolerance. The SIP4610BDT-T1-E3 samples load current via internal sensing and regulates using this external resistor.
Does SIP4610BDT-T1-E3 include thermal protection?
Yes, SIP4610BDT-T1-E3 includes thermal shutdown protection that activates at 165 °C junction temperature and resets at 145 °C (20 °C hysteresis). During sustained overload, it cycles on/off autonomously to prevent permanent damage. This behavior is confirmed in the datasheet's Figure 2 and "Operation at Current Limit and Thermal Shutdown" section.
What is the maximum power dissipation of SIP4610BDT-T1-E3 in SOT-23-5?
The maximum power dissipation of SIP4610BDT-T1-E3 in its thin SOT-23-5 package is 305 mW at TA = 70 °C, based on θJA = 180 °C/W and TJ(MAX) = 125 °C. Derating is required above 70 °C ambient (5.5 mW/°C), per Absolute Maximum Ratings table. Exceeding this limit risks thermal shutdown or reliability degradation.
Is SIP4610BDT-T1-E3 RoHS-compliant and lead-free?
Yes, SIP4610BDT-T1-E3 is RoHS-compliant and lead-free, as explicitly stated in the Vishay datasheet (Document Number: 73233, Rev. J). It uses a Pb-free finish on its thin SOT-23-5 package and meets JEDEC J-STD-020 moisture sensitivity level (MSL) requirements for surface-mount assembly.
