Product details
Overview
TLV809EA29DPWR from Texas Instruments is a push-pull, active-low voltage supervisor IC designed for reliable power-on reset and brownout detection in low-power systems. It features a 2.93 V ±0.5% threshold voltage, 200 ms fixed reset delay, 250 nA typical supply current, and operates across –40°C to +125°C. It is used in battery-powered microcontrollers, FPGA configuration circuits, and industrial sensor nodes requiring precise, ultra-low-power supervision.
For engineers reviewing the TLV809EA29DPWR datasheet, TLV809EA29DPWR pinout, TLV809EA29DPWR application, or TLV809EA29DPWR equivalent, key selection criteria include its X2SON-5 (DPW) package footprint, guaranteed RESET assertion down to 0.7 V VDD, glitch immunity against sub-10 µs transients, and compatibility with 1.7–6 V supply rails in space-constrained embedded designs.
Technical Context
The TLV809EA29DPWR integrates a precision bandgap reference, hysteresis-controlled comparator (VHYS = 0.9–1.5%), and a monostable timer to generate a deterministic 200 ms reset pulse after VDD recovers above VIT+ (2.93 V + VHYS). Its push-pull output drives RESET low without external pull-up components and maintains valid logic states down to VPOR = 0.7 V.
It implements built-in glitch immunity (tGI = 10 µs typical) that rejects fast VDD excursions below VIT– unless sustained ≥10 µs - preventing spurious resets during switching noise or transient load events. The device requires no external timing components and supports manual reset via MR pin (available only in DPW package).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.7 V to 6 V - supports single-cell Li-ion, 3.3 V, and 5 V rails without level-shifting. |
| Threshold Voltage (VIT–) | 2.93 V ±0.5% (typical) - enables accurate detection of 3.0 V rail brownout with minimal margin loss. |
| Reset Delay (tD) | 200 ms (variant A) - ensures sufficient hold time for slow-ramping power supplies or FPGA/ASIC initialization. |
| Quiescent Current (IDD) | 250 nA (typical) at 3.3 V - extends battery life in always-on monitoring applications for >10 years. |
| Output Type | Push-pull, active-low - eliminates need for external pull-up resistor and guarantees defined high-Z release state. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial PLC, and outdoor metering environments. |
| VPOR (Power-On Reset) | 700 mV - guarantees predictable RESET assertion even during ultra-low-voltage startup sequences. |
Pinout & Package
X2SON-5 (DPW) package: 0.8 mm × 0.8 mm, 0.35 mm height, thermal pad (PAD) on bottom - optimized for high-density PCB layouts and thermal dissipation in compact modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Primary return path for internal circuitry; must be connected to system ground plane for stable operation. |
| VDD | Supply input | Monitored voltage rail; powers internal reference, comparator, and output driver - bypass capacitor required. |
| RESET | Active-low reset output | Push-pull driver asserts low during fault; releases high after tD when VDD > VIT+ - no external pull-up needed. |
| MR | Manual reset input | Active-low pin (internal 100 kΩ pull-up); pulling low forces immediate RESET assertion - optional for system recovery. |
| PAD | Thermal pad | Non-electrical thermal interface; improves heat transfer to PCB copper - may be left floating or tied to GND. |
Key Features

Use Scenario: Handheld ultrasound probe with rechargeable LiPo battery and low-power ARM Cortex-M4 processor. IC Role / Device Role / Timing Role: Supervises 3.0 V analog front-end supply and triggers hard reset if battery voltage falls below 2.93 V during scan operation. Use Value: Avoids analog signal distortion or ADC saturation by halting acquisition before supply collapse - preserves diagnostic integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV809MA29DPWR | Same 2.93 V threshold and 200 ms delay, but rated only to +85°C (vs. +125°C); 1 µA max IDD vs. 250 nA typical. | Suitable for commercial-grade consumer electronics, not extended-temperature industrial or automotive use. | Select TLV809MA29DPWR only if ambient temperature stays ≤85°C and higher quiescent current is acceptable. |
| TPS3809K29DBVR | 2.93 V threshold, 200 ms delay, but open-drain output requiring external pull-up; 600 nA typical IQ; no MR pin. | Lacks manual reset and push-pull drive - adds BOM cost and layout area; less robust in noisy environments. | Choose TPS3809K29DBVR only if legacy open-drain interface is mandated or DPW package is unavailable. |

FAQ
What is the exact reset threshold voltage of TLV809EA29DPWR?
The TLV809EA29DPWR has a factory-programmed falling threshold voltage (VIT–) of 2.93 V with ±0.5% typical accuracy over –40°C to +125°C. This value is laser-trimmed during production and specified in Section 7.5 of the datasheet; actual units measure within 2.915 V to 2.945 V at 25°C.
Does TLV809EA29DPWR require an external pull-up resistor on the RESET pin?
No, TLV809EA29DPWR uses a push-pull output topology, so the RESET pin actively drives both high and low states. Unlike open-drain supervisors (e.g., TLV803E), it does not require an external pull-up resistor - simplifying BOM and reducing board area.
What is the minimum supply voltage at which TLV809EA29DPWR guarantees correct RESET assertion?
TLV809EA29DPWR guarantees defined RESET behavior down to VPOR = 700 mV. Below this voltage, the output state is undefined. This allows reliable power-on reset initiation even with weak batteries or slow-ramping supplies - a key advantage over older supervisors with 1.0 V+ VPOR.
Can TLV809EA29DPWR be used in place of MAX809 in existing designs?
Yes - TLV809EA29DPWR is pin-to-pin compatible with MAX809 (same SOT-23-3 pinout), but the DPW package is different. For drop-in replacement in SOT-23-3 footprints, use TLV809EA29DBVR. The DPW variant offers smaller size and added MR functionality, requiring PCB redesign.
What is the purpose of the MR pin on TLV809EA29DPWR?
The MR (Manual Reset) pin on TLV809EA29DPWR is an active-low input that forces RESET assertion regardless of VDD level when pulled low. It features an internal 100 kΩ pull-up resistor and is available only in the X2SON-5 (DPW) package - enabling field recovery or user-initiated reset without firmware involvement.
