Product details
Overview
TPS2400DBVTG4 from Texas Instruments is an overvoltage protection controller designed to isolate sensitive loads from destructive transients using an external N-channel MOSFET. It features a 6.9-V overvoltage shutdown threshold, 3-V undervoltage lockout, sub-1-µs turnoff time, and operates across −40°C to 85°C ambient temperature in a 5-pin SOT-23 package - deployed in automotive load-dump protection and portable electronics power rails.
For engineers reviewing the TPS2400DBVTG4 datasheet, TPS2400DBVTG4 pinout, TPS2400DBVTG4 application, or TPS2400DBVTG4 equivalent, key selection criteria include overvoltage response speed, gate drive capability for discrete N-MOSFETs, input voltage tolerance up to 100 V, thermal performance in small-outline packages, and compatibility with automotive-grade transient suppression requirements.
Technical Context
The TPS2400DBVTG4 integrates a trimmed band-gap reference, oscillator, charge pump, Zener diodes, comparator, and control logic to monitor VIN and drive an external N-channel MOSFET's gate. Its internal charge pump enables gate drive above source potential, supporting high-side switching configurations without external boost circuitry.
It implements dual-threshold protection: overvoltage detection triggers gate pull-down within <1 µs, while undervoltage lockout prevents operation below 2.9 V. The device draws ≤220 µA at 6.5 V input and maintains functional integrity under 100-V absolute maximum input stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Overvoltage Threshold | 6.9 V (typical); precise trip point for disconnecting load during automotive load dump or adapter misconnection) |
| Undervoltage Lockout | 3.0 V (typical upper threshold); prevents erratic operation during brownout or cold-start conditions |
| Turnoff Time | <1 µs (measured to 6.9 V gate voltage); ensures load isolation before transient energy propagates |
| Input Voltage Range | 3.1 V to 6.8 V (recommended operating); 100 V absolute max rating enables robust front-end survivability |
| Gate Drive Current | 485 mA sink (typical at 7.2 V VIN); sufficient to rapidly discharge gate capacitance of medium-power N-MOSFETs |
| Supply Current | 135–220 µA (at 6.5 V VIN); ultra-low quiescent draw supports always-on protection in battery-powered systems |
| Ambient Temperature | −40°C to +85°C; validated for industrial and automotive cabin environments |
| ESD Rating | ±2500 V HBM, ±500 V CDM; meets standard handling requirements for production assembly |
Pinout & Package
TPS2400DBVTG4 uses a 5-pin SOT-23 (DBV) package measuring 2.90 mm × 1.60 mm with 1.45 mm max height. Pin 1 is located in quadrant Q3 per tape-and-reel orientation standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 5) | Input voltage sense and supply | Primary input node; monitors system rail and powers internal circuitry; rated to 100 V absolute max |
| GATE (Pin 4) | Output gate driver | Drives external N-MOSFET gate; provides 485 mA sink current to ensure fast turnoff under overvoltage |
| GND (Pin 2) | Ground reference | Power and signal return path; must be low-impedance to support fast transient response and noise immunity |
| NC (Pins 1 & 3) | No internal connection | Unbonded terminals; must remain unconnected on PCB to avoid parasitic coupling or latch-up risk |
Key Features
| Feature | Design Value |
|---|---|
| Sub-1-µs overvoltage response | Ensures load disconnection before transient energy damages downstream ICs or capacitors |
| Integrated charge pump | Eliminates need for external boost supply when driving high-side N-MOSFETs with source above VIN |
| Trimmed 6.9-V OVP threshold | Enables precise protection alignment with 5-V or 3.3-V system rails without external resistor dividers |
| 1.45-mm max package height | Supports ultra-thin portable designs including media players and GPS modules where board space is constrained |
| −40°C to +85°C operation | Validated for deployment in automotive infotainment and industrial handheld equipment without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar overvoltage protection controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2400DBVRG4 | Same die, 3000-unit tape-and-reel packaging vs. 250-unit reel for TPS2400DBVTG4; identical electrical specs and pinout | Optimized for high-volume automated assembly rather than prototyping or low-quantity evaluation | Select TPS2400DBVRG4 for production runs; TPS2400DBVTG4 suits design validation and small-batch integration |
| TPD3S014TDR | Integrated 1.5-A load switch with OVP, ESD protection, and current limiting - no external MOSFET required but fixed 5.5-V OVP threshold | Targets USB port protection with integrated fault reporting; lacks programmable thresholds and discrete FET flexibility | Choose TPD3S014TDR for compact USB Type-A/B ports; retain TPS2400DBVTG4 when discrete FET selection, higher OVP precision, or >100-V tolerance is needed |
Compared with TPS2400DBVRG4, the TPS2400DBVTG4 offers identical protection functionality in smaller reel quantity for design iteration; versus TPD3S014TDR, it trades integration for design flexibility, higher voltage tolerance, and adjustable external FET optimization - critical for automotive and industrial applications demanding field-proven robustness.

FAQ
What is the primary function of the TPS2400DBVTG4 in a power system?
The TPS2400DBVTG4 functions as an overvoltage protection controller that monitors input voltage and rapidly disables power delivery to downstream circuitry via an external N-channel MOSFET. It does not regulate voltage or provide current limiting - its sole purpose is transient isolation with sub-microsecond response, making it ideal for safeguarding sensitive loads in automotive and portable electronics where fuse-based protection is undesirable. The TPS2400DBVTG4 achieves this through internal comparators, a charge pump, and a dedicated gate driver stage.
Can the TPS2400DBVTG4 operate with input voltages above 6.8 V?
Yes - the TPS2400DBVTG4 supports an absolute maximum input voltage of 100 V, though its recommended operating range is 3.1 V to 6.8 V. Operation above 6.8 V is permissible only during transient events such as automotive load dump; sustained operation outside the recommended range may impact long-term reliability and is not characterized for parametric performance. The TPS2400DBVTG4 remains functional and protective during those transients, but system design must ensure average input stays within spec to maintain guaranteed timing and threshold accuracy.
Which external MOSFET is referenced in the TPS2400DBVTG4 datasheet?
The TPS2400DBVTG4 datasheet references the FDC3616N as the companion N-channel MOSFET in application diagrams and test circuits. This 30-V, 4.5-A logic-level device was selected for its low gate charge and compatibility with the TPS2400DBVTG4's 485-mA gate sink capability, enabling fast turnoff. While the TPS2400DBVTG4 supports any N-MOSFET meeting gate drive and voltage requirements, the FDC3616N serves as the validated reference part for typical 5-V rail protection designs.
Does the TPS2400DBVTG4 require external passive components to function?
The TPS2400DBVTG4 requires no external resistors or capacitors for basic overvoltage/undervoltage protection - its thresholds are internally trimmed and its charge pump is self-contained. However, layout best practices mandate a 0.1-µF ceramic bypass capacitor between VIN and GND, placed within 2 mm of the TPS2400DBVTG4 pins. An optional RC network on the GATE pin can be added to control inrush slew rate, but it is not required for core protection functionality. All other components - including the external N-MOSFET - are mandatory for operation.
How does the TPS2400DBVTG4 differ from TVS diode-based protection?
Unlike TVS diodes that clamp overvoltage by shunting excess current to ground - often blowing a fuse in the process - the TPS2400DBVTG4 disconnects the load entirely using an external MOSFET. This makes it resettable, fuseless, and capable of surviving indefinite overvoltage events without degradation. The TPS2400DBVTG4 also provides precise 6.9-V thresholding versus TVS tolerance bands of ±10%, and avoids leakage current issues common with high-voltage TVS devices. Its <1-µs response is comparable to TVS, but its architecture eliminates post-event service requirements.
