Texas Instruments TLV6713DDCT

Overview

TLV6713DDCT from Texas Instruments is a micropower, 36-V comparator with integrated 400-mV precision reference and open-drain output, designed for undervoltage detection in battery-powered systems. It operates from 1.8 V to 36 V, delivers 0.75% threshold accuracy over temperature, consumes only 11 µA max supply current, and features 5.5 mV typical hysteresis. It is used in portable medical devices and door/window sensors where stable low-power voltage supervision is required.

For engineers reviewing the TLV6713DDCT datasheet, TLV6713DDCT pinout, TLV6713DDCT application, or TLV6713DDCT equivalent, this page provides verified functional identity, validated SOT-23-6 pin mapping, confirmed 400-mV threshold architecture, and real-world implementation constraints including 25-V output rating, 1.7-V SENSE input limit, and 155-µs startup delay.

Technical Context

The TLV6713DDCT implements a non-inverting single-channel comparator with internal 400-mV reference and built-in hysteresis (2–12 mV), enabling noise-immune undervoltage detection without external components. Its SENSE pin accepts inputs up to 1.7 V (7 V absolute max), independent of VDD, and exhibits ±25 nA input leakage across full supply range.

It uses an open-drain output rated to 25 V - independent of VDD - capable of sinking up to 10 mA, requiring an external pullup. The device enters undervoltage lockout below 1.5 V (typ) and power-on reset below 0.8 V, with propagation delays of 9.9 µs (HL) and 28.1 µs (LH) at 24 V.

Key Specifications

Pinout & Package

FAQ

What is the absolute maximum voltage rating on the SENSE pin of the TLV6713DDCT?

The TLV6713DDCT SENSE pin has an absolute maximum rating of 7 V, but its recommended operating range is limited to 0 V to 1.7 V. Exceeding 1.7 V may cause inaccurate threshold comparison or damage under sustained overvoltage. This constraint ensures compatibility with the internal 400-mV reference architecture and prevents input stage saturation. Always use a resistor divider to scale higher monitored voltages into this safe range before applying them to the TLV6713DDCT SENSE pin.

Can the TLV6713DDCT drive a 5-V logic input directly?

Yes, the TLV6713DDCT can drive a 5-V logic input directly using its open-drain output. Connect the OUT pin to the 5-V logic input through a pullup resistor to 5 V, ensuring VPULLUP does not exceed 25 V. The device's 25-V output rating and 10-mA sink capability allow robust interfacing with 5-V CMOS inputs. Verify that VOL remains ≤0.4 V at 5-V logic high threshold by selecting RP ≤50 kΩ (based on 250-mV max VOL at 5 mA sink), confirming clean logic-low assertion for the receiving device.

What is the minimum recommended pullup resistor value for TLV6713DDCT when used with a 3.3-V microcontroller GPIO?

The minimum recommended pullup resistor for TLV6713DDCT with a 3.3-V GPIO is calculated based on VOL ≤0.4 V (standard 3.3-V logic low) and maximum sink current of 10 mA. Using Ohm's Law: RP(min) = (3.3 V − 0.4 V) / 0.01 A = 290 Ω. However, typical designs use 10–100 kΩ to minimize current draw. For 3.3-V operation, 10 kΩ is optimal - yielding ~0.33 V VOL at 10 mA while keeping total current under 330 µA. This value balances noise immunity, speed, and power efficiency for the TLV6713DDCT.

Does TLV6713DDCT require an external capacitor on the VDD pin?

Yes, TI recommends placing a 0.1-µF ceramic capacitor between VDD and GND, located as close as possible to the TLV6713DDCT pins. This capacitor stabilizes the internal reference and comparator against supply transients and high-frequency noise. Without it, the device may exhibit erratic output behavior during load switching or EMI events. For systems with fast-rising supply rails (>1 V/µs) or high-voltage transients, add an RC filter (100 Ω + 0.01 µF) between source and VDD per Figure 17 in the TLV6713DDCT datasheet.

How does the TLV6713DDCT behave during power-up when VDD rises slowly?

During slow VDD ramp-up, the TLV6713DDCT enters Power-On Reset (POR) mode until VDD exceeds 0.8 V (min), then Undervoltage Lockout (UVLO) until VDD surpasses 1.5 V (typ). Only after VDD remains above UVLO for ≥155 µs does the device enter Normal Operation, allowing SENSE-to-OUT correlation. Below POR, OUT is high-impedance; between POR and UVLO, OUT is forced low regardless of SENSE. This staged activation prevents spurious outputs during brown-out conditions and ensures deterministic behavior for the TLV6713DDCT in real-world power sequences.
