Texas Instruments TPS2060DGNR

Overview

TPS2060DGNR from Texas Instruments is a dual-channel, current-limited, high-side power-distribution switch featuring two 70-mΩ N-channel MOSFETs, 1.5-A continuous output current per channel, active-low enable inputs (EN1/EN2), and open-drain overcurrent fault reporting (OC1/OC2). It operates from 2.7 V to 5.5 V and delivers controlled 0.6-ms rise time for inrush current limiting in USB host and hot-plug applications.

For engineers reviewing the TPS2060DGNR datasheet, TPS2060DGNR pinout, TPS2060DGNR application, or TPS2060DGNR equivalent, key selection criteria include dual-channel independent enable control, thermal + short-circuit protection with deglitched OC outputs, reverse current blocking, and DGN-8 package compatibility with PowerPad grounding for UL/CB-certified designs.

Technical Context

The TPS2060DGNR integrates two independent high-side N-channel MOSFET switches with internal charge-pump gate drive enabling operation down to 2.7 V input while maintaining fast, controlled switching (0.6-ms typical rise time). Each channel features dedicated logic-level enable (active low) and open-drain overcurrent flag (OCx), with no shared enable or fault reporting lines.

Protection architecture includes accurate current limiting (1.6 A min / 2.6 A max trip threshold), undervoltage lockout (2.0–2.5 V activation with 75 mV hysteresis), and thermal shutdown at ~135°C with 10°C hysteresis. Fault reporting is deglitched for 4–15 ms to suppress false OC assertions during capacitive load turn-on.

FAQ

What is the enable logic polarity for TPS2060DGNR?

The TPS2060DGNR uses active-low enable inputs: EN1 and EN2 must be pulled low to turn on OUT1 and OUT2 respectively. This differs from the TPS2064DGNR, which uses active-high enables. The datasheet confirms EN1/EN2 are labeled "I" (input) with "logic low turns on" behavior in the Pin Functions table for TPS2060.

Does TPS2060DGNR support reverse current blocking?

Yes, TPS2060DGNR provides inherent reverse current blocking when disabled. Its high-side N-channel MOSFET architecture prevents backflow from OUT to IN, a critical feature for USB OTG and modular systems where peripherals may remain powered while upstream supply is removed.

What is the purpose of the PowerPad in the DGN-8 package of TPS2060DGNR?

The PowerPad in the TPS2060DGNR's DGN-8 package serves dual functions: it provides primary thermal dissipation (reducing θJA to 137°C/W) and must be soldered to the PCB ground plane to meet UL E169910 and CB certification requirements. TI's SLMA002 application note specifies via placement and copper area guidelines.

How does the overcurrent (OC) output behave during thermal shutdown in TPS2060DGNR?

In TPS2060DGNR, the OC1 and OC2 outputs are asserted low during both overcurrent events and thermal shutdown conditions. The deglitch circuit applies only to overcurrent detection (4–15 ms timeout); thermal faults assert OC immediately without deglitching, ensuring rapid system-level fault response.

Can TPS2060DGNR operate from a 3.3-V supply?

Yes, TPS2060DGNR supports input voltages from 2.7 V to 5.5 V. At 3.3 V, its rDS(on) increases to 75–125 mΩ (vs. 70–115 mΩ at 5 V), resulting in higher conduction loss-but continuous 1.5-A operation remains valid per Recommended Operating Conditions. Rise time also decreases to ~0.4 ms at 2.7 V.
