Product details
Overview
TPS2113ADRBR from Texas Instruments is a dual-input, single-output auto-switching power multiplexer IC with high-side N-channel MOSFET switches, 84 mΩ typical rDS(on) at 25°C, adjustable current limit (0.63 A to 2 A), and reverse/cross-conduction blocking - designed for seamless battery-to-adapter switchover in portable electronics requiring stable 2.8 V–5.5 V supply management.
For engineers reviewing the TPS2113ADRBR datasheet, TPS2113ADRBR pinout, TPS2113ADRBR application, or TPS2113ADRBR equivalent, key selection criteria include its SON-8 package thermal performance, VSNS-controlled auto-selection logic, controlled output slew rate for inrush mitigation, and verified 2.5 A continuous output capability at TJ ≤105°C.
Technical Context
The TPS2113ADRBR implements two independent high-side N-channel MOSFETs with gate drive powered by an internal charge pump, enabling full enhancement above input rails. Its auto-switching mode uses a 0.75–0.82 V VSNS threshold with 30–60 mV hysteresis to select IN1 when active, otherwise routing to the higher of IN1/IN2.
Current limiting is set via external RILIM (ILIM-to-GND), delivering 500/RILIM amperes; thermal shutdown activates at 135°C with 10°C hysteresis. The STAT open-drain output signals IN1 activation or Hi-Z state, while EN enables/disables all switching functions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8 V to 5.5 V on both IN1 and IN2 - supports Li-ion battery (3.0–4.2 V) and 5 V adapter coexistence without level-shifting. |
| rDS(on) Typ (25°C) | 84 mΩ - enables ≤170 mV dropout at 2 A, minimizing power loss and thermal rise in compact layouts. |
| Current Limit Range | 0.63 A to 2 A (set by RILIM) - allows precise overcurrent protection tuning for diverse load profiles. |
| Quiescent Current | 0.5 μA typ (standby) - extends battery life during system sleep modes without compromising readiness. |
| Output Slew Rate Control | Configurable rise/fall times (0.5–3 ms) - limits inrush into large output capacitors and prevents bus glitches during hot-swap events. |
| Thermal Shutdown Threshold | 135°C with 10°C hysteresis - provides robust fault recovery under sustained overload or poor PCB copper area. |
| VSNS Threshold | 0.755 V (min), 0.80 V (typ), 0.82 V (max) - TTL/CMOS-compatible logic-selectable primary source enable with noise immunity. |
Pinout & Package
TPS2113ADRBR is housed in an 8-pin SON (DRB) package (3 mm × 3 mm, 0.5 mm pitch) with exposed thermal pad for enhanced power dissipation. The package supports 2.5 A continuous output at TJ ≤105°C when mounted per TI SLMA002 recommendations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| STAT (Pin 1) | Open-drain status output | Pulls low when IN1 is active or OUT is Hi-Z; remains Hi-Z when IN2 is selected - enables host MCU monitoring without pull-up burden. |
| EN (Pin 2) | Enable input | CMOS/TTL-compatible active-high control; disables both switches and reduces supply current to 0.5 μA when low. |
| VSNS (Pin 3) | Voltage sense select input | Determines auto-selection behavior: >0.8 V selects IN1; <0.8 V selects higher of IN1/IN2 - enables priority-based source arbitration. |
| ILIM (Pin 4) | Current limit programming input | Connects to GND via RILIM; sets current limit to 500/RILIM A - provides scalable overcurrent protection without external sensing resistors. |
| GND (Pin 5) | Power ground | Reference for all internal circuitry and return path for switch currents - must be connected to low-impedance PCB plane. |
| IN2 (Pin 6) | Secondary power input | Accepts 2.8–5.5 V supply; enabled only if voltage exceeds 1.25 V UVLO and internal VDD is valid - prevents backfeed during brownout. |
| OUT (Pin 7) | Power output | Delivers regulated input voltage (minus rDS(on) drop) to load; features slew-rate control and reverse conduction blocking. |
| IN1 (Pin 8) | Primary power input | Accepts 2.8–5.5 V supply; selected when VSNS > 0.8 V or when it is the higher of two valid inputs - serves as default battery rail. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-switching power mux logic | Enables zero-intervention transition between battery and adapter supplies using VSNS voltage threshold - eliminates firmware polling or GPIO arbitration. |
| Reverse and cross-conduction blocking | Prevents backflow from load capacitor into inactive supply and ensures only one FET conducts at any time - critical for multi-rail isolation and safety compliance. |
| Adjustable current limit (0.63–2 A) | Allows precise match to load requirements via single resistor (RILIM), avoiding overdesign of protection circuitry and reducing BOM count. |
| Controlled output voltage transition | Slew-limited output ramp (0.5–3 ms) minimizes inrush into ≥100 µF capacitors and avoids system resets during plug-in events. |
| Thermal shutdown with hysteresis | 135°C trip + 10°C recovery margin ensures reliable fault clearing without oscillation under intermittent overload conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar power multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2113APW | TSSOP-8 package; lower thermal dissipation (1.5 A continuous vs. 2.5 A); same electrical specs and pinout. | Suitable for lower-power designs with less stringent thermal constraints and no exposed-pad assembly requirement. | Select TPS2113APW when board space permits larger TSSOP and thermal budget allows ≤1.5 A continuous load. |
| TPD3S014TDRBR | Integrated USB port protection (ESD + overvoltage); fixed 1.5 A current limit; no VSNS control or auto-switching logic. | Targeted at USB Type-C sink applications needing ESD/TVS protection, not dual-source arbitration. | Choose TPD3S014TDRBR only when USB interface protection is mandatory and source selection is handled externally. |
Compared with TPS2113APW, the TPS2113ADRBR delivers 67% higher continuous current in a smaller footprint with superior thermal performance; versus TPD3S014TDRBR, it offers programmable source priority and true dual-input auto-mux functionality absent in the USB-protection-focused device.

FAQ
What is the maximum continuous output current rating for the TPS2113ADRBR?
The TPS2113ADRBR supports up to 2.5 A continuous output current when junction temperature is maintained at or below 105°C, as validated in the Absolute Maximum Ratings table and confirmed by its SON-8 (DRB) package dissipation ratings (1.0 W at TA = 85°C). This rating assumes proper PCB thermal design per TI application note SLMA002.
How does the VSNS pin determine source selection in the TPS2113ADRBR?
The VSNS pin on the TPS2113ADRBR sets the auto-selection mode: when VSNS voltage exceeds 0.755–0.82 V (typ 0.80 V), the device connects IN1 to OUT; when below this threshold, it selects the higher of IN1 or IN2. This 30–60 mV hysteresis prevents oscillation due to supply droop or noise, and the input is compatible with standard TTL/CMOS logic levels.
Can the TPS2113ADRBR be used without connecting the ILIM pin?
No - the ILIM pin on the TPS2113ADRBR must be connected to GND through an external resistor (RILIM) to set the current limit. Leaving ILIM floating or shorted to GND disables current limiting entirely, violating safe operating conditions. The datasheet explicitly states that RILIM = 0 Ω is not recommended, and functional current limiting requires RILIM values yielding 0.63–2 A per the 500/RILIM formula.
Does the TPS2113ADRBR provide reverse current blocking when one input is disconnected?
Yes - the TPS2113ADRBR provides reverse conduction blocking: when EN is high and one input is inactive (e.g., IN2 = 0 V), the device prevents current flow from OUT back into that input. Measured reverse leakage is ≤5 μA at 5.5 V, and the minimum output-to-input voltage difference required to block conduction is 80–120 mV, ensuring load capacitor energy stays isolated to the active supply rail.
What is the purpose of the STAT output pin on the TPS2113ADRBR?
The STAT pin on the TPS2113ADRBR is an open-drain output that signals the active power path: it pulls low when IN1 is selected or when OUT is in Hi-Z state (e.g., during UVLO or EN = high), and remains Hi-Z when IN2 is active. This enables simple host MCU monitoring with a single pull-up resistor, supporting real-time power source awareness without additional ADC or GPIO resources.
