Product details
Overview
TLV6703DDCR from Texas Instruments is a micropower, 18-V single-channel non-inverting comparator with integrated 400-mV reference, open-drain output rated to 18 V, ±0.5% threshold accuracy at 25°C, and 5.5 µA typical quiescent current - used for precision undervoltage monitoring in battery-powered systems.
For engineers reviewing the TLV6703DDCR datasheet, TLV6703DDCR pinout, TLV6703DDCR application, or TLV6703DDCR equivalent, this page delivers verified electrical specs, SOT-23-6 package mapping, real-world voltage-monitoring use cases, and two validated alternative comparators with documented functional and application-level differences.
Technical Context
The TLV6703DDCR implements a high-accuracy comparator core with internal 400-mV reference and built-in 5.5-mV typical hysteresis to reject noise-induced false triggering. Its SENSE input accepts voltages up to 6.5 V independent of VDD, enabling monitoring of rails higher than its supply.
It operates across 1.8 V to 18 V supply range, supports undervoltage lockout (UVLO) at 1.3–1.7 V, and features an open-drain OUT pin capable of sinking 40 mA while being pulled up to 18 V - decoupled from VDD voltage level.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 18 V - enables direct operation from 3.3-V, 5-V, 12-V, or 15-V rails without LDO pre-regulation. |
| Threshold Accuracy | ±0.5% max at 25°C, ±1.0% max over –40°C to +125°C - ensures reliable trip-point stability across automotive and industrial temperature ranges. |
| Quiescent Current | 5.5 µA typical - supports multi-year battery life in always-on voltage supervision circuits (e.g., IoT node wake-up monitors). |
| Input Threshold | 400 mV nominal rising threshold (VIT+) - fixed internal reference eliminates need for external precision reference IC. |
| Hysteresis | 5.5 mV typical - suppresses chatter during slow-rising/falling monitored voltages or in noisy environments (e.g., motor control power rails). |
| Output Type | Open-drain, 18-V tolerant - allows flexible pull-up to any logic rail (1.8 V to 18 V), interfacing directly with MCU reset inputs or FPGA enable pins. |
| Propagation Delay | 18 µs (HL), 29 µs (LH) at 5 V - sufficient for DC/DC converter UVLO, battery pack cutoff, and system power sequencing. |
Pinout & Package
TLV6703DDCR is packaged in a thin SOT-23-6 (DDC) package measuring 2.90 mm × 1.60 mm, optimized for space-constrained portable designs and compatible with standard pick-and-place assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 2, 4, 6) | Ground reference | All three GND pins must be connected to system ground to ensure stable reference and thermal performance. |
| OUT (Pin 1) | Open-drain output | Sinks current when SENSE falls below VIT–; high-impedance otherwise - requires external pullup resistor for logic-high assertion. |
| SENSE (Pin 3) | Monitoring input | Accepts 0–6.5 V input; compares against internal 400-mV reference - sets trip point via external resistor divider on monitored rail. |
| VDD (Pin 5) | Power supply input | 1.8–18 V supply; place 0.1-µF ceramic capacitor between VDD and GND near the pin for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 400-mV reference | Eliminates external reference IC and associated BOM cost, layout area, and calibration drift in voltage monitor designs. |
| 18-V output tolerance | Enables direct interface to 3.3-V, 5-V, or 12-V microcontroller reset inputs without level-shifting circuitry. |
| Low input bias current (±25 nA) | Permits use of megaohm-scale resistor dividers - reducing power loss in battery-supervised applications. |
| –40°C to +125°C operation | Validated for under-hood automotive, industrial PLC, and outdoor medical equipment deployments without derating. |
| Internal hysteresis (5.5 mV typ) | Prevents oscillation during threshold crossing in noisy environments - no external hysteresis resistor network required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV6700DDCR | Window comparator (dual-threshold); same 400-mV reference, but detects both overvoltage and undervoltage conditions. | Requires dual-resistor divider configuration; suited for battery charge/discharge window detection, not single-threshold UVLO. | Select TLV6700DDCR only when both upper and lower trip points must be enforced - e.g., Li-ion cell voltage guardbanding. |
| TLV6713DSER | Higher 36-V supply rating, 0.75% threshold accuracy over temperature, WSON-6 package (1.5 mm × 1.5 mm). | Supports 24-V industrial and 36-V automotive battery monitoring; smaller footprint but requires different PCB land pattern. | Choose TLV6713DSER for next-gen designs targeting wider VIN range and board-area reduction - not a drop-in replacement for TLV6703DDCR. |
Compared with TLV6703DDCR, TLV6700DDCR adds overvoltage detection capability at the cost of increased design complexity, while TLV6713DSER extends voltage range and shrinks size but demands layout revision and requalification for 18-V systems.

FAQ
What is the maximum input voltage allowed on the SENSE pin of the TLV6703DDCR?
The TLV6703DDCR SENSE pin accepts voltages from 0 V to 6.5 V, regardless of VDD level. This allows safe monitoring of rails higher than the device's supply - for example, using a resistor divider to scale a 12-V rail down to ≤6.5 V at SENSE. Exceeding 6.5 V risks damage per Absolute Maximum Ratings.
Does the TLV6703DDCR require an external reference voltage?
No, the TLV6703DDCR integrates a precision 400-mV reference internally. The SENSE pin is compared directly against this trimmed reference, eliminating the need for external reference ICs, voltage dividers for reference generation, or calibration components - simplifying BOM and layout.
Can the TLV6703DDCR output drive a 12-V logic input directly?
Yes. The TLV6703DDCR's open-drain OUT pin is rated to 18 V and can be pulled up to 12 V using an external resistor. When asserted low, it sinks current cleanly; when de-asserted, it presents high impedance - enabling direct interface with 12-V microcontroller reset or enable inputs without level shifters.
What is the purpose of the three GND pins on the TLV6703DDCR SOT-23-6 package?
The TLV6703DDCR uses three dedicated GND pins (2, 4, 6) in its SOT-23-6 (DDC) package to minimize ground path impedance, improve thermal dissipation, and reduce noise coupling into the sensitive comparator input. All three must be connected to a low-impedance system ground plane for specified accuracy and stability.
How does hysteresis function in the TLV6703DDCR, and what is its typical value?
The TLV6703DDCR includes built-in hysteresis of 5.5 mV (typical), implemented as a 5.5-mV offset between rising (VIT+) and falling (VIT–) thresholds. This prevents output oscillation during slow or noisy threshold crossings - for example, when monitoring a drooping battery voltage - without requiring external feedback resistors.
