Product details
Overview
SIP4610ADT-T1-E3 from Vishay Siliconix is a protected 1-A high-side load switch with active-low enable, 2.4–5.5 V supply range, user-settable current limit (0.75–1.25 A), 145 mΩ typical RDS(on) at 5 V, and integrated thermal shutdown/UVLO. It serves as a smart power rail controller in peripheral port and hot-swap circuits.
For engineers reviewing the SIP4610ADT-T1-E3 datasheet, SIP4610ADT-T1-E3 pinout, SIP4610ADT-T1-E3 application, or SIP4610ADT-T1-E3 equivalent, key selection criteria include enable polarity (active-low), RSET-based current limit configuration, SOT-23-5 thermal performance (305 mW @ 70 °C), and compatibility with AAT4610A in industrial temperature environments.
Technical Context
The SIP4610ADT-T1-E3 implements a PMOS-based high-side switch with external current limit programming via RSET connected between SET and GND. Its internal reference comparator monitors VSET to regulate output current dynamically, maintaining constant ILIMIT even under varying VIN/VOUT conditions.
Protection logic integrates undervoltage lockout (1.8–2.4 V rising threshold, 50 mV hysteresis), thermal shutdown (165 °C trip, 20 °C hysteresis), and <4 kV HBM ESD rating. The active-low ON/ON pin enables direct microcontroller GPIO control without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 1 A - supports sustained loads like USB peripherals or card readers without derating at 25 °C. |
| Supply Voltage Range | 2.4 V to 5.5 V - compatible with 3.3 V and 5 V system rails, including battery-backed inputs. |
| RDS(on) (Typical) | 145 mΩ at 5 V - yields <0.15 V dropout at 1 A, minimizing power loss and heat generation. |
| Quiescent Current | 9 µA - enables ultra-low standby power in always-on subsystems such as wake-on-LAN circuits. |
| Current Limit Accuracy | ±25 % - requires 33 % design headroom (via RSET coefficient) to guarantee minimum 1 A delivery under process/temp variation. |
| Thermal Shutdown Threshold | 165 °C - protects die during sustained overload; auto-recovery at 145 °C enables fault-tolerant cycling. |
| Enable Polarity | Active-low - simplifies interface with open-drain or push-pull MCU outputs driving low to activate. |
Pinout & Package
The SIP4610ADT-T1-E3 is housed in a RoHS-compliant thin SOT-23-5 package (1.6 mm × 2.9 mm × 1.1 mm), rated for -40 °C to +85 °C operation with θJA = 180 °C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Switch output node | Drives load; voltage follows IN when enabled, floats high-Z when disabled; must be decoupled locally. |
| 2 - GND | Power and signal reference | Common return path for IN, OUT, SET, and ON/ON; requires low-inductance PCB connection. |
| 3 - SET | Current limit programming input | Connects external resistor to GND; sets ILIMIT per RSET = 7100 / ILIMIT (e.g., 6.8 kΩ → 1 A). |
| 4 - ON/ON | Active-low enable control | Pulled low to turn on switch; high-impedance when inactive; VIH ≥ 2.0 V, VIL ≤ 0.8 V over full VIN range. |
| 5 - IN | Input supply and switch source | Primary power input; also supplies internal bias circuitry; max 6 V absolute rating. |
Key Features
| Feature | Design Value |
|---|---|
| User-configurable current limit | Set via single external resistor (RSET) - eliminates need for fixed-limit ICs or discrete current-sense amplifiers. |
| Low quiescent current (9 µA) | Reduces system standby power by >99 % vs. legacy high-side switches - critical for battery-powered PDAs and notebooks. |
| Integrated UVLO and thermal shutdown | Prevents malfunction during brown-out or overload without external supervision circuitry - improves BOM efficiency and reliability. |
| 4 kV HBM ESD rating | Withstands electrostatic discharge during handling and board assembly - reduces field failure risk in portable electronics manufacturing. |
| Compatible with AAT4610A | Enables drop-in replacement in existing designs using AAT4610A - simplifies component obsolescence mitigation. |
Applications
| USB Peripheral Port Protection | Hot-Swap Power Sequencing |
|---|---|

IC Role / Device Role / Timing Role: Low-leakage (1 µA shutdown) power gate with active-low enable synchronized to ACPI signals. Use Value: Extends battery life by cutting off idle module leakage; maintains fast wake-up (<200 µs turn-on) for responsive UX. | Use Scenario: Safely powering SD/MMC slots during card insertion/removal in handheld devices. IC Role / Device Role / Timing Role: Overcurrent-protected high-side switch with thermal foldback to prevent damage during card short events. Use Value: Avoids data corruption and slot damage by clamping current at 1 A and cycling during sustained shorts. |
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 |
|---|---|---|---|
| AAT4610A-T1 | Same functional spec, identical pinout, same SOT-23-5 package; manufactured by Advanced Analogic Technologies (acquired by Skyworks). | No change in layout or firmware; verified drop-in replacement per Vishay documentation. | Select when sourcing legacy AAT4610A stock or requiring dual-source procurement. |
| TPS22965DRLR | TI part with 1.5 A rating, 34 mΩ RDS(on), but fixed 1.5 A current limit and no RSET adjustability. | Requires redesign of current-limit network; better for low-dropout needs but less flexible for variable load profiles. | Choose for higher current or lower conduction loss where programmability is not required. |
Compared with SIP4610ADT-T1-E3, AAT4610A-T1 offers identical functionality and pin compatibility for seamless migration, while TPS22965DRLR trades programmable current limiting for lower RDS(on) and higher current capacity - making it suitable only when fixed-limit operation and reduced voltage drop are prioritized over design flexibility.

FAQ
What is the enable polarity of the SIP4610ADT-T1-E3?
The SIP4610ADT-T1-E3 features an active-low enable input (pin 4, labeled ON/ON). Driving this pin low enables the high-side switch; pulling it high disables the output. This matches the SIP4610A variant designation and allows direct interfacing with standard microcontroller GPIOs configured as open-drain or push-pull outputs.
How do I set the current limit for the SIP4610ADT-T1-E3?
To set the current limit for the SIP4610ADT-T1-E3, connect an external resistor (RSET) between pin 3 (SET) and GND. For a 1 A limit, use a 6.8 kΩ resistor (RSET = 7100 / ILIMIT). The actual limit varies ±25 % due to process and temperature, so design with 33 % headroom to ensure minimum required current delivery.
Does the SIP4610ADT-T1-E3 provide reverse voltage protection?
No, the SIP4610ADT-T1-E3 does not provide reverse voltage protection. It is designed for forward current flow only (IN → OUT). If OUT voltage exceeds IN, reverse current may flow through the body diode of the internal PMOS, bypassing current limiting and potentially damaging the device. External reverse-blocking diodes or MOSFETs are required in bidirectional or charging applications.
What thermal protection mechanisms does the SIP4610ADT-T1-E3 include?
The SIP4610ADT-T1-E3 includes thermal shutdown with a 165 °C trip point and 20 °C hysteresis. When junction temperature exceeds 165 °C, the device turns off and remains off until temperature falls to ~145 °C, then automatically recovers. This protects against sustained overload or poor PCB heatsinking, especially critical in compact SOT-23-5 layouts.
Is the SIP4610ADT-T1-E3 RoHS compliant and lead-free?
Yes, the SIP4610ADT-T1-E3 is RoHS compliant and lead-free, packaged in a lead (Pb)-free thin SOT-23-5. The "-E3" suffix in the part number explicitly denotes Vishay's lead-free, halogen-free, and RoHS-compliant construction per JEDEC J-STD-020 standards.
