Product details
Overview
SiP32501DNP-T1-GE4 from Vishay Siliconix is a single-channel, high-side load switch IC with 66 mΩ typical RDS(on), operating from 0.9 V to 2.5 V input voltage and supporting up to 1.2 A continuous current. It integrates an output discharge switch, reverse current blocking, and a pull-down on the EN pin - designed for low-voltage power rail control in portable electronics.
For engineers reviewing the SiP32501DNP-T1-GE4 datasheet, SiP32501DNP-T1-GE4 pinout, SiP32501DNP-T1-GE4 application, or SiP32501DNP-T1-GE4 equivalent, key selection criteria include its 9.8 μs rise time, 0.05 μs turn-on delay at 2.5 V, integrated slew-rate control, and compatibility with sub-1.0 V GPIO logic without level shifting.
Technical Context
The SiP32501DNP-T1-GE4 implements an n-channel MOSFET high-side switch with internal charge pump to maintain constant gate-to-source voltage across the 0.9–2.5 V input range, ensuring stable RDS(on). Its enable threshold is hysteresis-enabled: VIL ≤ 0.1 V (min) and VIH ≥ 1.5 V (min), allowing direct interface with low-voltage controllers.
It features active output discharge (integrated pulldown switch with 425 Ω typical RPD) and reverse blocking capability (IRB ≤ 10 nA at VOUT = 2.5 V, VIN = 0.9 V). Thermal design is constrained by θJA = 170 °C/W and a maximum junction temperature of +125 °C under continuous operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input voltage range | 0.9 V to 2.5 V - supports core logic rails including 1.0 V, 1.2 V, 1.8 V, and 2.5 V domains without external bias |
| RDS(on) (typ.) | 66 mΩ at 2.5 V - enables <100 mV drop at 1.2 A, minimizing power loss and thermal rise |
| Turn-on delay td(on) | 0.05 μs at 2.5 V - ensures rapid power sequencing in multi-rail systems |
| Rise time tr | 9.8 μs at 2.5 V - provides controlled inrush limiting to prevent supply droop and system reset |
| Quiescent current IQ | 10 μA typical at 1.2 V - extends battery life in always-on subsystems |
| Reverse blocking current | ≤10 nA - prevents backfeed from higher-voltage outputs (e.g., USB OTG, shared battery rails) |
| Output discharge resistance | 425 Ω typical - actively discharges output capacitance within ~100 μs (100 nF load) |

| 3 - EN | Enable logic input | CMOS-compatible; internal 100 kΩ pull-down ensures default OFF state; accepts VEN up to 2.75 V |
| 4 - IN | n-Channel MOSFET drain | Input power rail connection; requires 4.7 μF ceramic bypass for transient suppression |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| TPS22915YZPR | Higher RDS(on) (85 mΩ typ.), no integrated output discharge, 1.05 V min. VIN | Lacks active discharge; requires external pulldown for fast VOUT decay | Choose when cost sensitivity outweighs discharge requirement and input voltage ≥1.05 V |
| NIS5020MN3T1G | Wider VIN range (1.5–6.5 V), higher RDS(on) (120 mΩ), no slew control | Not suitable for sub-1.5 V rails; uncontrolled turn-on risks inrush-induced brownouts | Prefer only for 3.3 V/5 V systems where SiP32501DNP-T1-GE4's low-VIN capability is unnecessary |
Compared with TPS22915YZPR and NIS5020MN3T1G, the SiP32501DNP-T1-GE4 uniquely supports 0.9 V operation with integrated slew control and discharge - critical for modern ultra-low-power mobile SoCs where rail collapse and wake-up latency must be tightly managed.

FAQ
What is the minimum input voltage supported by the SiP32501DNP-T1-GE4?
The SiP32501DNP-T1-GE4 operates down to 0.9 V input voltage, verified across temperature and load conditions per Vishay's S20-0532-Rev. C datasheet. This enables direct use with advanced SoC core rails such as 0.95 V GPU domains and LPDDR4x I/O supplies without external regulation or boosting.
Does the SiP32501DNP-T1-GE4 provide reverse current blocking?
Yes, the SiP32501DNP-T1-GE4 provides reverse current blocking with ≤10 nA leakage when disabled and VOUT > VIN, as confirmed in the "Reverse Blocking Current vs. Output Voltage" characteristic (Fig. 14) and "DETAILED DESCRIPTION" section of the datasheet.
Is an external capacitor required on the EN pin of the SiP32501DNP-T1-GE4?
No external capacitor is required on the EN pin of the SiP32501DNP-T1-GE4. The device includes an internal pull-down resistor (~100 kΩ) and hysteresis, making it immune to noise without added RC filtering - validated in the "EN Input Leakage" and "EN Threshold Voltage vs. Input Voltage" (Fig. 15) test data.
What is the thermal resistance (θJA) of the SiP32501DNP-T1-GE4 in standard PCB layout?
The SiP32501DNP-T1-GE4 has a junction-to-ambient thermal resistance (θJA) of 170 °C/W when mounted with all leads and the exposed thermal pad soldered to a 1-in² 2-oz copper plane, per the Absolute Maximum Ratings table and thermal considerations section of the datasheet.
Can the SiP32501DNP-T1-GE4 drive a 100 μF output capacitor safely?
Yes - the SiP32501DNP-T1-GE4's slew-rate control ensures safe turn-on even with 100 μF output capacitance. At 2.5 V input, its 9.8 μs rise time limits peak inrush to <2.5 A (calculated via dV/dt × C), well below the 2 A pulsed current rating and within safe SOA limits defined in the datasheet.
