Texas Instruments TPS2013PWRG4

Overview

TPS2013PWRG4 from Texas Instruments is a high-side N-channel MOSFET power-distribution switch in SOIC-8 package, delivering 2.6 A typical short-circuit current limit at 25°C, 95 mΩ max on-state resistance at 5.5 V input, and logic-compatible enable control. It provides thermal shutdown (≈180°C), electrostatic discharge protection (12 kV on OUT), and controlled 3.5–4 ms rise/fall times for EMI reduction - used in USB peripheral power management and hot-swap circuits.

For engineers reviewing the TPS2013PWRG4 datasheet, TPS2013PWRG4 pinout, TPS2013PWRG4 application, or TPS2013PWRG4 equivalent, key selection criteria include its 2.7–5.5 V operating range, 10 µA standby current, SOIC-8 drop-in compatibility with Siliconix Littlefoot™ PMOS switches (with GND connected), and integrated current-limit/thermal-protection behavior under sustained overload.

Technical Context

The TPS2013PWRG4 implements a charge-pump–driven gate driver that sustains MOSFET turn-on down to 2.7 V input, operating at 100 kHz without external components. Its internal sense FET enables accurate current limiting without series resistive loss, switching the output into constant-current mode when load exceeds 2.6 A (typ) at 25°C.

Thermal protection uses junction-sense hysteresis: shutdown occurs near 180°C, with automatic recovery after ~20°C cooldown. The device's dual IN pins (pins 2 & 3) and quad OUT pins (pins 5–8) reduce PCB trace resistance and power dissipation under high-current loads.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous output current rating for TPS2013PWRG4?

The TPS2013PWRG4 does not specify a continuous output current rating independent of thermal conditions; instead, it features a current-limit function that holds output current at 2.6 A (typical) during overload or short-circuit events. Continuous operation at this level depends on PCB copper area, ambient temperature, and airflow - with thermal shutdown activating near 180°C junction temperature to prevent damage.

Does TPS2013PWRG4 require external components for basic operation?

No, the TPS2013PWRG4 operates autonomously with no external components required for core functionality. Its internal 100 kHz charge pump needs no external capacitors, and logic-level enable control eliminates level-shifters. However, TI recommends a 0.1 µF ceramic bypass capacitor between IN and GND, plus optional 0.1 µF output decoupling, to ensure stability and ESD immunity.

How does the thermal protection mechanism work in TPS2013PWRG4?

The TPS2013PWRG4 incorporates an internal thermal-sense circuit that disables the power switch when junction temperature reaches approximately 180°C. After shutdown, the device remains off until the junction cools by ~20°C, then automatically resumes operation. This hysteresis prevents oscillation and allows safe cycling during persistent faults until the root cause is removed.

Is TPS2013PWRG4 pin-compatible with older Siliconix Littlefoot™ devices?

Yes - the TPS2013PWRG4 in SOIC-8 package is explicitly documented as a drop-in replacement for Siliconix Littlefoot™ PMOS power switches, provided GND (Pin 1) is connected. Unlike the original PMOS parts, TPS2013PWRG4 uses an N-channel high-side architecture with charge-pump drive, offering lower R_DS(on) and improved efficiency at low input voltages.

What is the significance of the "G4" suffix in TPS2013PWRG4?

The "G4" suffix in TPS2013PWRG4 denotes Texas Instruments' green packaging standard: lead-free (Pb-free), RoHS-compliant construction with NiPdAu lead finish. It confirms compliance with environmental regulations and specifies the same MSL Level-1 (260°C peak reflow) and -40°C to 85°C operating temperature range as the base part number.
