Texas Instruments TPS2010APWP

Overview

TPS2010APWP from Texas Instruments is a 0.3-A rated, 50-mΩ N-channel high-side power distribution switch in a 14-pin TSSOP package, operating from 2.7 V to 5.5 V with logic-level enable, thermal/short-circuit protection, and 6.1-ms typical rise time - used for hot-plug current limiting in USB peripheral ports and embedded module power rails.

For engineers reviewing the TPS2010APWP datasheet, TPS2010APWP pinout, TPS2010APWP application, or TPS2010APWP equivalent, key selection criteria include its 0.3-A short-circuit current limit, 50-mΩ on-resistance at 5 V, -40°C to 85°C ambient rating, active-low enable compatibility with 3-V/5-V logic, and absence of drain-source back-gate diode for true high-side isolation.

Technical Context

The TPS2010APWP integrates an N-channel MOSFET high-side switch with internal charge pump gate drive, enabling operation down to 2.7 V while maintaining controlled 6.1-ms output rise time to suppress inrush current and EMI. Its current-limit circuit uses a sense FET (not external resistor) to enter constant-current mode at 0.3 A when overload or short occurs.

Thermal shutdown activates at ~140°C junction temperature with ~20°C hysteresis, enabling automatic recovery after cooling; undervoltage lockout disables the switch below ~2 V input, ensuring safe startup and hot-insertion behavior. The device draws only 10 μA standby current when disabled.

FAQ

What is the exact short-circuit current limit of the TPS2010APWP?

The TPS2010APWP has a typical short-circuit output current limit of 0.3 A at 25°C, with a minimum of 0.22 A and maximum of 0.4 A across process and temperature. This value is fixed per device variant and confirmed in the Electrical Characteristics table of the SLVS189C datasheet. The TPS2010APWP maintains this limit regardless of input voltage between 2.7 V and 5.5 V, making it predictable for system-level fault analysis.

Does the TPS2010APWP have a body diode, and how does that affect reverse current?

No, the TPS2010APWP does not have a drain-source back-gate diode - a deliberate design choice confirmed in the datasheet's "No Drain-Source Back-Gate Diode" feature. This eliminates reverse current flow from OUT to IN, enabling true high-side isolation. In applications like battery backup or shared-bus systems, this prevents unintended discharge or contention when upstream power is removed while downstream loads remain active.

Can the TPS2010APWP operate from a 3.3-V supply, and what is its on-resistance at that voltage?

Yes, the TPS2010APWP operates fully across 2.7 V to 5.5 V, including 3.3-V nominal supplies. At 3.3 V and 25°C, its static drain-source on-resistance is 37 mΩ typical (max 41 mΩ), per the Electrical Characteristics table. This results in ≤3.7 mW conduction loss at 0.3-A load - well within thermal limits of the TSSOP package under standard airflow conditions.

How does the thermal shutdown behavior of the TPS2010APWP recover after fault removal?

The TPS2010APWP thermal protection circuit shuts off the switch when junction temperature reaches ~140°C and automatically restores operation once the die cools by ~20°C - i.e., recovery begins near 120°C. This hysteresis prevents oscillation during marginal faults. Recovery is fully autonomous; no external reset or enable toggle is needed. The device resumes normal switching once thermal equilibrium is restored, as verified in Figure 29 and Detailed Description section.

Is the TPS2010APWP pin-compatible with other members of the TPS201xA family, such as TPS2011APWP?

No - all TPS201xA variants (TPS2010A, TPS2011A, TPS2012A, TPS2013A) share identical pinout and package dimensions in both SOIC and TSSOP options, including TPS2010APWP and TPS2011APWP. They differ only in factory-trimmed current-limit threshold (0.3 A vs 0.9 A), with no changes to pin function, timing, or protection behavior. PCBs designed for one can accept any variant without modification.
