Product details
Overview
The SIP32441DNP-T1-GE4 from Vishay Siliconix is a 3 A, fault-protected, slew-rate-controlled high-side load switch in a TDFN4 package, operating from 1.7 V to 5.5 V input with 38 mΩ typical RDS(on) at 1.8–5 V, -2 V negative input tolerance, and 2.5 ms controlled turn-on for inrush current limiting in portable power rails.
For engineers reviewing the SIP32441DNP-T1-GE4 datasheet, SIP32441DNP-T1-GE4 pinout, SIP32441DNP-T1-GE4 application, or SIP32441DNP-T1-GE4 equivalent, key selection criteria include its reverse current blocking capability, UVLO threshold of 2.3 V, <10 nA off-switch current, and compatibility with space-constrained mobile designs requiring robust fault protection and low quiescent current (38 μA typical).
Technical Context
The SIP32441DNP-T1-GE4 integrates an N-channel MOSFET with charge-pump gate drive to maintain flat RDS(on) across 1.7–5.5 V input range. Its internal UVLO circuit ensures turn-on only when VIN exceeds 2.3 V, independent of EN state in certain conditions.
A dedicated reverse-blocking circuit prevents current flow from OUT to IN when the switch is off or VIN = 0 V, while the EN pin features ~1 MΩ internal pull-down and logic-level compatibility up to 6 V. The device implements latch-based fault detection per truth table states, enabling reliable operation in both removable and embedded system configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.7 V to 5.5 V - supports single-cell Li-ion, USB, and wide-input portable rails without external regulation |
| Max Continuous Current | 3 A - sufficient for high-current peripherals like displays, SSDs, or USB ports |
| RDS(on) (typ.) | 38 mΩ at 1.8–5 V - minimizes conduction loss and thermal rise under full load |
| Slew Rate Control | 2.5 ms typical turn-on time at 3.6 V - limits inrush into 1000+ μF capacitive loads, preventing rail droop |
| Reverse Blocking | ≤10 nA at VOUT = 5 V, VIN = 0 V - eliminates backfeed into source during hot-swap or battery removal |
| UVLO Threshold | 2.3 V (EN open) - ensures stable logic operation before enabling power delivery |
| ESD Rating | HBM > 6 kV - enables direct integration into handheld devices without additional ESD protection |
Pinout & Package
Package: TDFN4, 1.2 mm × 1.6 mm, thermally enhanced with exposed GND pad - optimized for compact PCB layouts and thermal dissipation in thin-profile consumer devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: IN | Power input | Accepts 1.7–5.5 V supply; tolerates -2 V transient without damage or excessive current draw |
| 2: GND | Ground reference | Common return path for logic and power; must be connected to exposed thermal pad for θJA = 170 °C/W |
| 3: EN | Enable control | Logic-high active (VIH ≥ 1.3 V at VIN = 1.8 V); includes internal ~1 MΩ pull-down for default-OFF behavior |
| 4: OUT | Switched output | Delivers regulated load power; reverse-blocking circuit prevents current flow to IN when OFF |
Key Features
| Feature | Design Value |
|---|---|
| Fault-protected enable logic | Truth-table-defined latch behavior ensures deterministic ON/OFF transitions even during voltage sequencing anomalies |
| Negative input voltage tolerance | -2 V on IN/EN pins - withstands system-level transients without clamping diodes or external protection |
| Ultra-low shutdown current | 6.3 μA typical IQ(off) - extends battery life in always-on subsystems such as real-time clocks or sensors |
| Integrated slew rate control | No external RC network required - built-in timing delivers consistent 2.5 ms turn-on across temperature and voltage |
| Reverse current blocking | Active blocking at both forward and reverse bias - eliminates need for external back-to-back FETs or diodes |

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 |
|---|---|---|---|
| TPS22965DSGR | Higher RDS(on) (42 mΩ min), no negative voltage tolerance, 2.5 V min VIN | Lacks -2 V fault tolerance and UVLO independence from EN; requires external UVLO if VIN dips below 2.5 V | Choose when board space allows larger 1.6 mm × 2.1 mm DSG package and system lacks negative transients |
| AP22653AW5-7 | Lower current rating (2 A), no integrated slew rate control, 1.2 V min VIN | Requires external RC for inrush control; unsuitable for >2 A loads or systems needing guaranteed 2.5 ms soft-start | Prefer for ultra-low-VIN (1.2 V) battery-powered IoT nodes where 3 A capacity is unnecessary |
Compared with TPS22965DSGR and AP22653AW5-7, the SIP32441DNP-T1-GE4 uniquely combines -2 V input tolerance, 3 A continuous rating, and factory-trimmed 2.5 ms slew rate in a 1.2 mm × 1.6 mm footprint-making it optimal for space-constrained, fault-prone mobile power domains where reliability trumps marginal cost savings.

FAQ
What is the maximum continuous current rating for the SIP32441DNP-T1-GE4?
The SIP32441DNP-T1-GE4 is rated for 3 A maximum continuous switch current under recommended thermal conditions. This limit is enforced by internal design constraints-even though absolute maximum pulsed current reaches 12 A, sustained operation above 3 A risks exceeding junction temperature limits and violating reliability specifications. Derating is required above 25 °C ambient per the θJA = 170 °C/W thermal resistance.
Does the SIP32441DNP-T1-GE4 provide reverse current blocking when VIN is grounded?
Yes, the SIP32441DNP-T1-GE4 provides active reverse current blocking when VIN = 0 V or is floating, with reverse blocking current ≤10 nA at VOUT = 5 V. This function operates independently of EN state and is enabled by internal circuitry that isolates OUT from IN in the OFF state-critical for preventing backfeed in battery-backed or hot-swap systems.
How does the UVLO feature behave when the EN pin is left open on the SIP32441DNP-T1-GE4?
When EN is open, the SIP32441DNP-T1-GE4 uses an internal ~1 MΩ pull-down to hold EN low, but its UVLO circuit remains active: the switch turns ON only when VIN exceeds 2.3 V (UVLO threshold), regardless of EN state. If VIN rises above UVLO before EN is asserted, the device latches ON and cannot be turned OFF via EN alone-requiring VIN to drop below UVLO or a fault condition to reset.
Can the SIP32441DNP-T1-GE4 tolerate negative voltage on the IN pin during system faults?
Yes, the SIP32441DNP-T1-GE4 tolerates -2 V on the IN pin without damage or malfunction, drawing only -15 mA typical at VIN = -2 V. This capability eliminates the need for external clamping diodes in systems prone to inductive kickback or connector reversal, and is verified per absolute maximum ratings-not just guaranteed by design.
What is the typical slew rate control time for the SIP32441DNP-T1-GE4 at 3.6 V input?
The SIP32441DNP-T1-GE4 delivers a typical turn-on rise time of 2.5 ms at 3.6 V input under standard test conditions (RLOAD = 10 Ω, CL = 0.1 μF). This factory-trimmed value is process-stable across temperature and voltage, enabling predictable inrush limiting without external components-unlike discrete solutions requiring manual RC tuning.
