Product details
Overview
TPS2410PWR from Texas Instruments is a full-featured N+1 and ORing power rail controller IC that controls an external N-channel MOSFET to emulate a low-forward-voltage diode in redundant power systems. It supports 0.8 V to 16.5 V bus voltages, features linear gate control, internal charge pump for positive gate drive up to 12.5 V (vs A), and operates across –40°C to 85°C. It is used in rack servers and telecom systems requiring fault-tolerant power combining.
For engineers reviewing the TPS2410PWR datasheet, TPS2410PWR pinout, TPS2410PWR application, or TPS2410PWR equivalent, this page delivers verified specifications, validated pin functions, confirmed thermal and electrical behavior, and real-world implementation context for N+1 ORing and input-bus redundancy designs.
Technical Context
The TPS2410PWR implements linear turn-on control with soft-start to minimize bus transients, and uses dual comparator paths - one fast-turnoff path (programmable via RSET) and one filtered path (via FLTR capacitor) - to distinguish between fault reversals and benign noise. Its gate driver references BYP to A, enabling precise high-side N-FET control without external level shifters.
It integrates UV/OV monitoring (0.6 V thresholds), open-drain PG and FLTB outputs, STAT-based threshold shifting, and shorted-gate detection. The device enters thermal shutdown at 135°C with 10°C hysteresis and draws ≤6 mA typical VDD current during active regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bus Voltage Range | 0.8 V to 16.5 V - enables use with low-voltage server rails (e.g., 1.2 V, 3.3 V) and higher intermediate buses (12 V). |
| Gate Drive Voltage (vs A) | Up to 12.5 V - ensures robust N-MOSFET enhancement even at low VDD (≥3 V), eliminating need for external gate drivers. |
| Fast Turn-off Threshold | Programmable from –170 mV to +5 mV via RSET - allows precise tuning of reverse-current trip point for system stability under load transients. |
| Forward Regulation Voltage | 7–13 mV - sets low conduction loss equivalent to <1 mΩ effective diode resistance at 1 A, reducing heat and improving efficiency. |
| PG & FLTB Outputs | Open-drain, 4 mA sink capability - supports wired-OR configuration across multiple controllers and direct interface to FPGA/ASIC fault monitors. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and telecom environments where ambient temperature cycling impacts long-term reliability. |
| Thermal Shutdown | 135°C with 10°C hysteresis - protects against sustained overloads while allowing recovery without manual reset. |
Pinout & Package
TPS2410PWR is packaged in a 14-pin TSSOP (PW package), 5.00 mm × 4.40 mm body size, with exposed thermal pad (not electrically connected). Pin numbering follows standard top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Power input for charge pump and logic | Must be ≥3 V; supplies internal gate driver and bias circuits - decoupling with 0.01 µF near pin is mandatory. |
| RSET (Pin 2) | Turn-off threshold programming input | Resistor-to-GND sets fast comparator trip voltage; open = ~+3 mV; 3.24 kΩ = –142 mV - critical for light-load stability. |
| STAT (Pin 3) | Multifunction status/output | High = GATE actively driven; pulled low shifts turn-off threshold negative by ~157 mV - enables coordinated multi-rail fault response. |
| FLTB (Pin 4) | Open-drain fault indicator | Asserts low on VDD UVLO, gate failure, or V(A-C) > 0.425 V - includes 3.4 ms deglitch to reject ESD/EFT false triggers. |
| OV (Pin 5) | Overvoltage monitor input | 0.6 V threshold; when exceeded, forces GATE low and pulls PG low - usable as active-high disable signal. |
| UV (Pin 6) | Undervoltage monitor input | 0.6 V threshold; contributes to PG assertion but does not affect GATE - must be tied to GND if unused. |
| GND (Pin 7) | Power and signal reference | Carries high di/dt gate discharge current; requires low-impedance connection to PCB ground plane. |
| GATE (Pin 8) | N-MOSFET gate driver output | Drives gate referenced to A; delivers 2.35 A pulsed sink for <130 ns turn-off - trace must be short and wide. |
| RSVD (Pin 9) | Reserved power terminal | Must be connected to GND - not floating; ties internal substrate and improves thermal performance. |
| C (Pin 10) | Simulated diode cathode sense | Connects to MOSFET drain; Kelvin-sense path required to avoid IR drop errors in high-current ORing paths. |
| A (Pin 11) | Simulated diode anode sense | Connects to MOSFET source; also serves as charge pump reference - low-noise, low-inductance routing essential. |
| FLTR (Pin 12) | Fast comparator filter input | Capacitor-to-A adds RC delay (e.g., 150 pF → 7–52 ns) to reject sub-µs transients while preserving fault response. |
| BYP (Pin 13) | Charge pump output | Supplies internal comparators and gate driver; requires 800–2200 pF ceramic cap to A - no DC voltage applied externally. |
| PG (Pin 14) | Open-drain Power Good output | Open when UV OK, OV OK, and VDD ≥2.5 V - supports system-level power sequencing and health monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Linear gate control | Enables smooth MOSFET turn-on with <13 mV forward regulation - eliminates inrush spikes and reduces EMI vs on/off methods. |
| Internal charge pump | Generates gate drive voltage referenced to A - supports N-MOSFETs without external boost supplies or level shifters. |
| Programmable fast turn-off | RSET resistor adjusts trip point from +5 mV to –170 mV - allows optimization for bus capacitance, load step, and fault margin. |
| STAT-driven threshold shift | Pulling STAT low during operation shifts fast comparator threshold negative by ~157 mV - enables synchronized multi-controller fault response. |
| Shorted-gate detection | Monitors GATE voltage relative to A and asserts FLTB if gate fails to rise - prevents uncontrolled bus coupling during MOSFET failure. |
| Thermal shutdown with hysteresis | Shuts down at 135°C and resumes at 125°C - protects against sustained overload without latch-up or external intervention. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ORing controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2411PWR | Uses on/off gate control instead of linear; fixed fast turn-off threshold (~–13 mV); no RSET programmability. | Better suited for high-efficiency, low-noise systems where soft-start is less critical than minimal conduction loss. | Select TPS2411PWR when deterministic turn-on timing and lower quiescent current (≤1.2 mA) outweigh need for adjustable regulation. |
| LTC4357IMS8E#PBF | Operates down to 2.5 V bus; includes automatic retry after fault; no internal charge pump - requires external gate driver for N-FETs. | Preferred in battery-backed or low-voltage industrial systems where VDD headroom is constrained below 3 V. | Choose LTC4357IMS8E#PBF only when bus voltage falls below 3 V or when integrated retry logic is required for unattended recovery. |
Compared with TPS2410PWR, TPS2411PWR trades linear control for simpler threshold behavior and lower IQ, while LTC4357IMS8E#PBF extends low-voltage operation at the cost of external component count and loss of integrated charge pump functionality.

FAQ
What is the minimum VDD voltage required for TPS2410PWR to operate?
The TPS2410PWR requires VDD ≥3 V to enable gate drive and internal circuitry. Below 2.5 V, the internal UVLO disables operation and pulls PG low. At exactly 3 V, gate drive voltage reaches ~6–7 V (vs A), sufficient to fully enhance most logic-level N-MOSFETs. Operation at VDD = 3 V is fully specified and supported across temperature.
Can TPS2410PWR control P-channel MOSFETs?
No, TPS2410PWR is designed exclusively for N-channel MOSFETs. Its gate driver is referenced to the A pin (anode/sense node) and provides positive voltage relative to A - incompatible with P-FET source-referenced gate requirements. Using a P-FET would require inversion, level-shifting, and external bias, voiding all TPS2410PWR specifications and reliability guarantees.
How does the RSET resistor affect TPS2410PWR behavior in a dual-redundant system?
In dual-redundant systems, RSET sets the fast turn-off threshold for each TPS2410PWR independently. If both units share identical RSET values, they respond identically to reverse voltage events. Interconnecting STAT pins allows one unit pulling STAT low to shift *both* units' thresholds negative by ~157 mV - enhancing coordinated fault isolation without additional logic.
Is the FLTR pin required for basic TPS2410PWR operation?
No, FLTR is optional. Leaving FLTR unconnected (open) yields fastest comparator response (<100 ns), suitable for clean, low-noise buses. Adding a capacitor from FLTR to A introduces intentional delay (e.g., 150 pF → ~7 ns for 100-mV reversal) to suppress ESD/EFT false trips - recommended for high-dI/dt or RF-noisy environments like telecom shelves.
What happens to the GATE output of TPS2410PWR during thermal shutdown?
During thermal shutdown (>135°C), TPS2410PWR disables active gate drive and sustains a resistive pull-down on GATE to prevent floating. This ensures the external MOSFET remains safely OFF until junction temperature drops to ~125°C, at which point normal operation resumes automatically - no reset or power cycle is needed.
