Product details
Overview
TPS2413PWRG4 from Texas Instruments is an N-channel MOSFET-based ORing power rail controller for redundant power bus management, featuring on/off gate control, 3 V to 16.5 V supply range, 0.8 V to 16.5 V bus voltage support, 10 mV forward turnon threshold, and fast 1–5 mV programmable turnoff threshold. It enables diode-emulation in rack server N+1 PSU and telecom input-ORing applications.
For engineers reviewing the TPS2413PWRG4 datasheet, TPS2413PWRG4 pinout, TPS2413PWRG4 application, or TPS2413PWRG4 equivalent, key selection criteria include gate drive compatibility with discrete N-MOSFETs, RSET-programmable reverse-current trip point, thermal shutdown at 135°C, soft turnon for bus transient suppression, and SOIC/TSSOP package suitability for high-density power modules.
Technical Context
The TPS2413PWRG4 implements comparator-based on/off MOSFET control-driving GATE high when V(A−C) exceeds 10 mV and triggering rapid pulldown upon falling below a user-programmed negative threshold via RSET. Unlike the linear-regulating TPS2412, it avoids regulation-induced gate impedance at light load, eliminating output droop during large step loads.
Its internal charge pump generates gate drive voltage referenced to pin A, enabling positive gate control up to 12.5 V relative to A. Fast turnoff uses a two-stage current sink (2.35 A pulsed + 19.5 mA sustained), ensuring <130 ns turnoff time with 10 nF gate capacitance and preserving bus integrity during reverse-fault events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Control Method | On/off comparator with hysteresis - eliminates light-load voltage droop and supports fast step-load response |
| Forward Turnon Threshold | 7–13 mV - sets minimum forward bias required to activate external MOSFET |
| Fast Turnoff Threshold | Programmable from –170 mV to –10 mV via RSET - defines precise reverse-current trip point |
| Supply Voltage Range | 3 V to 16.5 V on VDD - powers internal logic and charge pump independent of bus voltage |
| Bus Voltage Range | 0.8 V to 16.5 V between A and C pins - supports low-voltage server rails and 12 V telecom buses |
| Gate Drive Voltage | Up to 12.5 V above pin A - ensures full enhancement of standard logic-level N-MOSFETs |
| Thermal Shutdown | 135°C with 10°C hysteresis - protects device during sustained overload or poor PCB thermal design |

TPS2413PWRG4 is packaged in an 8-pin TSSOP (PW) with 4.40 mm × 3.00 mm body size and exposed pad for thermal performance. Pin functions are validated per TI SLVS728D Rev D.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power input | Supplies internal charge pump and logic; must be ≥3 V; bypassed with 0.01 μF capacitor |
| RSET | Threshold programming input | Resistor-to-GND sets fast turnoff voltage; open = slightly positive trip (~3 mV) |
| RSVD | Reserved power | Must be connected to GND; not internally used but required for proper operation |
| GND | Ground reference | Return path for charge pump, gate discharge, and sensing circuits; low-impedance layout critical |
| GATE | MOSFET gate driver output | Drives external N-MOSFET gate positively relative to A; delivers 2.35 A pulsed sink current |
| C | Cathode sense input | Connects to MOSFET drain; senses bus-side voltage; clamped against >0.7 V reverse differential |
| A | Anode sense input | Connects to MOSFET source; serves as reference for BYP charge pump and V(A−C) measurement |
| BYP | Charge pump output | Internal bias supply for comparators and GATE driver; requires 2200 pF ceramic cap to A |
Key Features
| Feature | Design Value |
|---|---|

IC Role / Device Role / Timing Role: TPS2413PWRG4 manages input ORing by turning off the lower-voltage PSU's MOSFET to prevent backfeeding and bus collapse. Use Value: Supports seamless failover with <130 ns MOSFET turnoff, avoiding bus undervoltage lockout during input source switching. |
| Battery Backup Unit | Merchant network & server PSU |
Use Scenario: Li-ion battery pack and primary DC bus are ORed to supply uninterrupted power to critical loads during AC outage. IC Role / Device Role / Timing Role: TPS2413PWRG4 isolates battery from main bus when mains is present, and enables battery discharge only when bus voltage drops below threshold. Use Value: Programmable RSET allows precise matching of battery cutoff voltage to system brownout threshold, preventing premature switchover. | Use Scenario: Modular server PSUs use ORing controllers to parallel outputs into a common 12 V or 48 V distribution rail. IC Role / Device Role / Timing Role: TPS2413PWRG4 replaces discrete Schottky diodes in each PSU output stage, enabling bidirectional isolation and dynamic load sharing. Use Value: Reduces conduction loss from ~0.4 V (diode) to <50 mV (MOSFET), cutting heat generation and enabling higher power density in 1U form factor. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ORing controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2412PWRG4 | Linear gate control with 10 mV regulation; no programmable negative turnoff; soft turnoff above fast threshold | Better suited for mid-rail re-regulated buses where light-load droop must be avoided | Select TPS2412PWRG4 when bus voltage stability under light load is prioritized over step-load response |
| TPS2410DGQR | Includes fast-comparator filtering, STAT pin for dynamic threshold shift, and MOSFET fault monitoring | Required for noisy power environments (e.g., industrial UPS) where transient immunity is critical | Choose TPS2410DGQR when EMI or layout-induced noise causes false turnoff in TPS2413PWRG4 designs |
Compared with TPS2412PWRG4, the TPS2413PWRG4 trades regulation stability for faster transient response and simpler RSET configuration; compared with TPS2410DGQR, it omits filtering and status signaling to reduce cost and footprint in noise-controlled server environments.

FAQ
What is the function of the RSET pin on the TPS2413PWRG4?
The RSET pin on the TPS2413PWRG4 programs the fast turnoff threshold voltage via an external resistor to GND. A higher resistance yields a less negative trip point (e.g., 28.7 kΩ → –13.25 mV), while lower values set deeper negative thresholds (e.g., 3.24 kΩ → –142 mV). Leaving RSET open results in a ~3 mV positive threshold, which may cause instability at light load and is not recommended for TPS2413PWRG4.
Can the TPS2413PWRG4 drive a P-channel MOSFET?
No, the TPS2413PWRG4 is designed exclusively for N-channel MOSFETs. Its gate driver provides positive voltage relative to pin A (the simulated diode anode), which connects to the MOSFET source. Driving a P-channel device would require negative gate drive relative to source - a capability not supported by the TPS2413PWRG4 internal architecture or pinout.
What is the maximum bus voltage the TPS2413PWRG4 can control between pins A and C?
The TPS2413PWRG4 supports bus voltages from 0.8 V to 16.5 V between pins A and C. Absolute maximum ratings allow up to 18 V differential, but operation beyond 16.5 V violates recommended conditions and risks violating the 12.5 V max GATE-to-A voltage limit or exceeding internal comparator headroom. For 48 V systems, external level-shifting or alternative controllers like TPS2491 are required.
How does the TPS2413PWRG4 differ from the TPS2412PWRG4 in practical circuit behavior?
The TPS2413PWRG4 uses on/off comparator control, delivering full MOSFET conduction immediately at turnon and sharp cutoff at programmed threshold - ideal for low-voltage buses with large load steps. The TPS2412PWRG4 employs linear regulation to hold V(A−C) at 10 mV, causing variable gate voltage and higher effective RDS(on) at light load. This makes TPS2413PWRG4 preferable where step-load droop must be eliminated.
Is the TPS2413PWRG4 RoHS compliant and lead-free?
Yes, the TPS2413PWRG4 is RoHS compliant and lead-free. Per Texas Instruments' official packaging information, the PW (TSSOP) package variant carries the "G4" suffix indicating lead-free, halogen-free, and RoHS-compliant construction meeting JEDEC J-STD-020 moisture sensitivity level 2a requirements.
