Product details
Overview
TPS3707-33DGNG4 from Texas Instruments is a precision 3.3 V supply-voltage supervisor IC with active-low and active-high reset outputs, fixed 200 ms power-on reset delay, power-fail comparator (PFI/PFO), and manual reset input (MR). It operates from 2 V to 6 V, draws ≤50 µA supply current, and is rated for –40°C to 85°C ambient temperature. Used in microcontroller-based systems requiring reliable power sequencing and brownout detection.
For engineers reviewing the TPS3707-33DGNG4 datasheet, TPS3707-33DGNG4 pinout, TPS3707-33DGNG4 application, or TPS3707-33DGNG4 equivalent, key selection criteria include dual-reset polarity support, 2.93 V threshold accuracy over temperature, MSOP-PowerPAD™ 8-pin package compatibility, and absence of watchdog functionality compared to TPS3705 variants.
Technical Context
The TPS3707-33DGNG4 implements a precision bandgap reference and comparator architecture to monitor VDD against a factory-trimmed 2.93 V threshold (VIT–) with 50 mV hysteresis. It asserts active-low RESET when VDD falls below VIT– and releases it after a fixed 200 ms delay upon recovery above VIT+, while simultaneously driving active-high RESET with complementary timing.
Its dedicated PFI input accepts external voltage dividers for secondary rail monitoring (e.g., battery or auxiliary supply), triggering PFO output within 0.5–1 µs. MR provides asynchronous reset initiation, and all outputs are specified for 1 mA sink (RESET) and 500 µA source (RESET) drive strength under recommended operating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 6 V - supports wide-input industrial and embedded rails without external regulation |
| VDD Threshold (VIT–) | 2.93 V ±0.06 V at –40°C to 85°C - ensures accurate 3.3 V system brownout detection |
| Reset Delay Time | 200 ms fixed - eliminates need for external timing capacitor; guarantees processor initialization stability |
| Supply Current (IDD) | ≤50 µA max - enables low-power operation in battery-backed or energy-constrained designs |
| Output Types | Active-low RESET + active-high RESET - provides native interface compatibility with both reset-active-low and reset-active-high processors |
| Power-Fail Response | PFI input with 1.25 V threshold, PFO output with 0.5–1 µs propagation - enables fast low-battery or auxiliary-rail fault signaling |
| Operating Temperature | –40°C to 85°C - qualified for industrial and automotive under-hood environments |
Pinout & Package
TPS3707-33DGNG4 is packaged in an 8-pin MSOP-PowerPAD™ (DGN) with 3.00 mm × 3.00 mm body size and exposed thermal pad. The PowerPAD enhances thermal performance (RθJB = 45.1°C/W) and requires PCB soldering for optimal heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: RESET | Active-low reset output | Drives low during VDD undervoltage or MR assertion; sinks 1 mA; used for standard microcontroller reset inputs |
| 2: RESET | Active-high reset output | Complementary to Pin 1; sources 500 µA; interfaces directly with processors requiring high-valid reset |
| 3: MR | Manual reset input | Active-low; initiates reset when pulled low; internal pull-up not present - requires external pull-up |
| 4: VDD | Supply voltage input | Accepts 2–6 V; powers internal reference, comparators, and outputs; decoupling capacitor required |
| 5: GND | Ground reference | Return path for all internal circuits and outputs; must be connected to system ground plane |
| 6: PFI | Power-fail comparator input | Monitors external voltage divider; triggers PFO when input falls below 1.25 V threshold |
| 7: PFO | Power-fail comparator output | Active-low open-drain output; requires external pull-up; signals secondary rail failure |
| 8: NC | No internal connection | Not bonded; must remain unconnected - no routing or termination permitted |
Key Features
| Feature | Design Value |
|---|---|
| Dual-polarity reset outputs | Simultaneous active-low and active-high RESET signals eliminate level-shifting or inverter logic in mixed-architecture systems |
| Fixed 200 ms reset delay | Guaranteed timing without external RC components reduces BOM count, layout area, and calibration risk |
| 3.3 V precision threshold (2.93 V) | Factory-trimmed VIT– with ±0.06 V tolerance over full temperature range ensures robust 3.3 V rail supervision |
| Integrated power-fail comparator | PFI/PFO pair enables independent monitoring of backup batteries or auxiliary supplies with sub-microsecond response |
| Low quiescent current (≤50 µA) | Minimizes standby power draw in always-on or battery-operated applications such as smart sensors and portable instrumentation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3707-33DR | Same electrical specs and pinout; SOIC-8 (3.90 mm × 4.90 mm) instead of MSOP-PowerPAD™ | Larger footprint; lower thermal performance (RθJB = 58.5°C/W vs. 45.1°C/W); no exposed pad | Select for legacy board compatibility or cost-sensitive non-thermal-limited designs |
| MAX706TSA+ | Pin-compatible with MAX705–708 family; 3.08 V threshold; 200 ms delay; no active-high RESET output | Single-reset polarity only; higher supply current (80 µA typ); no PFI/PFO function | Select only if dual-reset outputs are unnecessary and MAX70x footprint reuse is mandatory |
Compared with TPS3707-33DR and MAX706TSA+, the TPS3707-33DGNG4 uniquely delivers dual-reset polarity in a thermally enhanced MSOP-PowerPAD™ package with integrated power-fail monitoring - critical for space-constrained, high-reliability, and multi-rail systems.

FAQ
What is the exact reset threshold voltage for TPS3707-33DGNG4 and how does it vary with temperature?
The TPS3707-33DGNG4 has a nominal negative-going input threshold voltage (VIT–) of 2.93 V, with guaranteed limits of 2.87 V (min) and 3.00 V (max) across –40°C to 85°C. Typical variation is ±0.5% over temperature, confirmed by Figure 7-2 in the datasheet. This precision enables reliable 3.3 V rail supervision without margining concerns in industrial environments.
Does TPS3707-33DGNG4 include a watchdog timer function?
No, the TPS3707-33DGNG4 does not include a watchdog timer. It is explicitly differentiated from the TPS3705-xx series, which integrates WDI/WDO pins and 1.6 s timeout. The TPS3707-33DGNG4 instead provides complementary RESET/RESET outputs and retains PFI/PFO functionality - making it ideal for systems needing dual-polarity reset without watchdog overhead.
What is the purpose of the NC pin on TPS3707-33DGNG4, and how should it be handled on the PCB?
Pin 8 of the TPS3707-33DGNG4 is designated NC (No Connection) and is not internally bonded. It must remain unconnected - no trace routing, solder mask opening, or copper pour should contact this pad. Leaving it floating prevents unintended coupling or ESD paths, and aligns with TI's layout guidance in Section 11.1 of the datasheet.
Can TPS3707-33DGNG4 monitor a 5 V supply, or is it limited to 3.3 V systems?
The TPS3707-33DGNG4 is optimized for 3.3 V VDD supervision (2.93 V threshold), but its PFI input can monitor any voltage rail - including 5 V - using an external resistor divider. For example, a 5 V rail can be scaled to 1.25 V at PFI using standard resistors, triggering PFO when the 5 V supply drops below the derived threshold. VDD itself must remain within 2–6 V.
How does the thermal performance of TPS3707-33DGNG4 compare between MSOP-PowerPAD™ and SOIC packages?
The TPS3707-33DGNG4 in MSOP-PowerPAD™ (DGN) achieves RθJB = 45.1°C/W, significantly better than the SOIC-8 (D) version's 58.5°C/W. This 23% improvement in junction-to-board thermal resistance allows higher sustained power dissipation or operation in hotter ambient conditions - especially valuable in dense industrial PCB layouts where airflow is limited.
