Product details
Overview
TPS1100PW from Texas Instruments is a single P-channel enhancement-mode MOSFET optimized for high-side power distribution in 3-V/5-V battery-powered systems. It features a maximum VGS(th) of –1.5 V, typical rDS(on) of 0.18 Ω at VGS = –10 V, and TTL/CMOS-compatible inputs-enabling direct microcontroller control in portable load management circuits such as notebook computer power rails.
For engineers reviewing the TPS1100PW datasheet, TPS1100PW pinout, TPS1100PW application, or TPS1100PW equivalent, key selection criteria include its ultrathin TSSOP-8 package, 2 kV ESD protection per MIL-STD-883C, –15 V drain-to-source rating, –40°C to 125°C operating temperature range, and suitability for low-voltage PWM-controlled power switching where board height and footprint are constrained.
Technical Context
The TPS1100PW operates as a high-side switch using P-channel enhancement-mode architecture with LinBiCMOS process optimization. Its gate threshold voltage (–1.5 V max) ensures reliable turn-on from 3-V logic, while low leakage (IDSS ≤ 0.5 µA at 25°C) minimizes standby current in battery-critical applications.
Dynamic performance includes 10 ns typical rise time and 2 ns fall time under VDD = –10 V, RL = 10 Ω, ID = –1 A conditions. The device integrates on-chip ESD protection (2 kV HBM) and requires no external VCC, simplifying integration into space-constrained portable designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | –15 V - Supports full operation across 3-V and 5-V rail systems with margin against transients. |
| rDS(on) | 0.18 Ω typ at VGS = –10 V - Enables <100 mW conduction loss at 750 mA, critical for thermal management in sealed enclosures. |
| VGS(th) | –1.5 V max - Guarantees robust turn-on from standard 3-V CMOS/TTL outputs without level-shifting. |
| ID Continuous | ±1.27 A at TA = 25°C (PW package) - Sufficient for powering peripheral modules like PCMCIA cards or display backlights. |
| ESD Rating | 2 kV per MIL-STD-883C Method 3015 - Meets industrial handling requirements without additional external protection. |
| Package | TSSOP-8 (PW) - 3.0 mm × 4.4 mm × 1.2 mm profile enables placement in ultra-thin handheld devices. |
| Switching Speed | 10 ns rise / 2 ns fall - Supports high-frequency PWM control up to ~35 MHz for efficient DC-DC converter synchronization. |
Pinout & Package
TPS1100PW uses an 8-pin ultrathin TSSOP (PW) package with exposed pad for thermal dissipation. All source pins must be connected together; all drain pins must be connected together per datasheet note A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Source | Common high-side return path; parallel connection required to achieve rated current and minimize resistance. |
| 5 | GATE | Control input accepting 3-V logic levels; negative VGS turns device ON. |
| 6, 7, 8 | Drain | High-side power output node; connects to load; multiple pins reduce trace inductance and improve current sharing. |
Key Features
| Feature | Design Value |
|---|---|
| 3-V logic compatibility | Guaranteed turn-on with VGS(th) ≤ –1.5 V enables direct interface to microcontrollers and PMICs without gate drivers. |
| Ultrathin TSSOP-8 package | 1.2 mm max height allows use in sub-10 mm thick consumer electronics where SOIC is physically incompatible. |
| No external VCC required | Self-contained biasing eliminates auxiliary supply routing, reducing BOM count and layout complexity. |
| Low IDSS leakage | ≤0.5 µA at 25°C preserves battery life in always-on monitoring circuits such as real-time clock backup rails. |
| Integrated ESD protection | 2 kV HBM rating meets MIL-STD-883C without requiring external TVS diodes on gate or drain lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side P-channel MOSFET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS1100D | SOIC-8 package (4.9 mm × 6.0 mm × 1.75 mm); higher RθJA (158°C/W vs 248°C/W); same electrical specs. | Preferred where board height >1.75 mm is acceptable and legacy SOIC footprints exist. | Select TPS1100D only when mechanical redesign for TSSOP is impractical and thermal derating is verified. |
| Si2301DS | 0.14 Ω rDS(on) at –4.5 V; 0.95 A ID continuous; SOT-23-3 package; no integrated ESD protection. | Better conduction efficiency but requires external ESD protection and lacks multi-pin drain/source for high-current paths. | Choose Si2301DS only for cost-sensitive, low-current (<500 mA), non-military applications with added protection circuitry. |
Compared with TPS1100D and Si2301DS, the TPS1100PW uniquely balances ultrathin packaging, integrated 2 kV ESD, and multi-pin terminations for high-current reliability-making it optimal for next-generation portable electronics where volume and height constraints dominate.

FAQ
What is the maximum continuous drain current for the TPS1100PW at 25°C ambient temperature?
The TPS1100PW supports ±1.27 A continuous drain current at TA = 25°C in its PW package, as specified in the Absolute Maximum Ratings table. This value assumes standard FR4 PCB mounting with no heatsinking and accounts for thermal derating above 25°C using a 4.03 mW/°C factor.
Does the TPS1100PW require an external gate pull-up resistor?
No, the TPS1100PW does not require an external gate pull-up resistor because it functions as a high-side P-channel switch: the gate is actively driven low to turn ON and pulled high (to source potential) to turn OFF. External resistors are only needed for slew-rate control or noise immunity in specific layouts.
Can the TPS1100PW be used in a 1.8-V logic system?
The TPS1100PW is not guaranteed to operate reliably with 1.8-V logic due to its VGS(th) specification of –1.5 V max; a 1.8-V system provides only –1.8 V VGS, which may yield marginal or inconsistent turn-on. For 1.8-V systems, TI recommends evaluating the TPS229xx series instead.
What is the thermal resistance (RθJA) of the TPS1100PW package?
The TPS1100PW has a junction-to-ambient thermal resistance (RθJA) of 248°C/W when mounted on a standard FR4 board with no special thermal enhancements. This value is used to calculate power derating curves and maximum allowable power dissipation at elevated ambient temperatures.
Is the TPS1100PW RoHS compliant and lead-free?
Yes, the TPS1100PW is RoHS compliant and features NiPdAu (NIPDAU) lead finish. Its MSL rating is Level-1 at 260°C peak reflow, and it is qualified for standard lead-free soldering processes without special handling requirements.
