Product details
Overview
SIP4282DVP-3-T1-E3 from Vishay Siliconix is a slew-rate-controlled high-side load switch built around a low-RDS(on) p-channel MOSFET, supporting 1.2 A continuous current at input voltages from 1.8 V to 5.5 V, featuring under-voltage lockout (UVLO) at 1.4 V and 100 μs typical turn-on slew rate. It integrates fast output discharge and operates with ultra-low quiescent current (2.5 μA typ.) for battery-powered portable electronics.
For engineers reviewing the SIP4282DVP-3-T1-E3 datasheet, SIP4282DVP-3-T1-E3 pinout, SIP4282DVP-3-T1-E3 application, or SIP4282DVP-3-T1-E3 equivalent, key selection considerations include UVLO presence, 100 μs slew control, TDFN4 1.2 mm × 1.6 mm package footprint, and compatibility with 1.8–5.5 V systems requiring controlled inrush current management.
Technical Context
The SIP4282DVP-3-T1-E3 implements linear gate voltage ramping during turn-on to achieve precise 100 μs slew control, avoiding capacitive load surge currents. Its internal UVLO circuit disables the switch when VIN falls below 1.4 V (typ.), preventing MOSFET saturation and ensuring safe operation during brownout conditions.
It features TTL/CMOS-compatible ON/OFF logic input, integrated 180 Ω output pulldown resistor for rapid load discharge upon disable, and operates across –40 °C to +85 °C ambient temperature with thermal derating above 70 °C. The device uses no external components for basic functionality beyond recommended 1 μF input and 0.1 μF output bypass capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.8 V to 5.5 V - supports Li-ion, USB, and multi-rail portable power domains without level-shifting. |
| RDS(on) @ 5 V | 105 mΩ (typ.) - enables <125 mW conduction loss at 1.2 A, minimizing thermal rise in compact layouts. |
| Turn-On Slew Rate | 100 μs (typ.) - limits inrush dI/dt to ~12 A/s, protecting downstream capacitance and upstream source. |
| UVLO Threshold | 1.4 V (typ.) - ensures reliable shutdown before supply collapse compromises system stability or data integrity. |
| Quiescent Current | 2.5 μA (typ.) - extends battery life in always-on standby modes (e.g., RTC or sensor bias rails). |
| Output Discharge Resistance | 180 Ω (typ.) - discharges 100 μF load to <10% VOUT in <1.5 ms, enabling fast power-state transitions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side slew-controlled load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS22967DQAR | Lower RDS(on) (42 mΩ @ 5 V), but fixed 200 μs slew rate; no UVLO; 1.65–5.5 V range. | Lacks UVLO and offers slower slew - unsuitable for brownout-prone battery systems requiring 1.4 V cutoff. | Prefer SIP4282DVP-3-T1-E3 where UVLO and tighter slew control are mandatory for system reliability. |
| AP22653AW5-7 | 100 μs slew and UVLO (1.3 V), but higher RDS(on) (180 mΩ @ 5 V); 1.8–5.5 V range; same TDFN package. | Higher conduction loss increases thermal stress at 1.2 A; less suitable for thermally constrained handheld enclosures. | Choose SIP4282DVP-3-T1-E3 for lower power loss and better thermal margin in space-constrained designs. |
Compared with TPS22967DQAR and AP22653AW5-7, SIP4282DVP-3-T1-E3 uniquely balances 100 μs slew precision, 1.4 V UVLO accuracy, and 105 mΩ RDS(on) in a 1.2 mm × 1.6 mm footprint-enabling robust, low-loss power sequencing in battery-critical portable systems without design trade-offs.

FAQ
What is the UVLO threshold voltage for SIP4282DVP-3-T1-E3?
The SIP4282DVP-3-T1-E3 features an under-voltage lockout (UVLO) threshold of 1.4 V (typical) with 250 mV hysteresis. When input voltage falls below this threshold, the device disables the p-channel MOSFET to prevent unstable operation or saturation. This behavior is confirmed in the Absolute Maximum Ratings and Specifications tables of Vishay document 65740, and applies specifically to the "D" variant (with UVLO), including SIP4282DVP-3-T1-E3.
Does SIP4282DVP-3-T1-E3 require external components for basic operation?
SIP4282DVP-3-T1-E3 operates with no external active components. However, Vishay recommends a 1 μF ceramic capacitor between IN and GND, and a 0.1 μF ceramic capacitor between OUT and GND for stable slew control and noise suppression. These are specified in the Application Information section of datasheet 65740 and are required for reliable 100 μs turn-on performance across temperature and load conditions.
What is the maximum continuous current rating for SIP4282DVP-3-T1-E3?
The SIP4282DVP-3-T1-E3 is rated for 1.2 A continuous switch current, as defined in the Absolute Maximum Ratings table (document 65740). This limit holds across the full operating temperature range (–40 °C to +85 °C) and input voltage range (1.8 V to 5.5 V), assuming proper PCB thermal design-including connection of the exposed thermal pad to a sufficient copper pour.
How does the output discharge function work in SIP4282DVP-3-T1-E3?
When the ON/OFF pin is driven low, SIP4282DVP-3-T1-E3 activates an internal 180 Ω (typ.) pulldown resistor between OUT and GND. This discharges capacitive loads rapidly-e.g., clearing a 100 μF capacitor to <10% of VOUT in under 1.5 ms. The feature is integrated and requires no external circuitry, as verified in the DETAILED DESCRIPTION and SPECIFICATIONS sections of Vishay document 65740.
Is SIP4282DVP-3-T1-E3 pin-compatible with other SiP4282 variants?
Yes - SIP4282DVP-3-T1-E3 uses the TDFN4 1.2 mm × 1.6 mm package with identical pinout (ON/OFF, IN, GND, OUT) as all SiP4282xNP3 and SiP4282xDNP3 variants. Pin mapping is confirmed in Figure 3 and PIN DESCRIPTION table of document 65740. However, functional differences exist: SIP4282DVP-3-T1-E3 includes UVLO, whereas "A" variants (e.g., SiP4282ADNP3-T1GE4) omit UVLO but extend VIN down to 1.5 V.
