Texas Instruments TPS3710DDCR

Overview

TPS3710DDCR from Texas Instruments is an automotive-grade wide-input-voltage precision voltage detector IC with open-drain output, 400mV internal reference, ±1.0% over-temperature threshold accuracy, and 5.5µA typical quiescent current. It monitors supply rails from 1.8V to 18V using external resistor dividers and asserts reset/enable signals in industrial control, microcontroller power sequencing, and FPGA power management systems.

For engineers reviewing the TPS3710DDCR datasheet, TPS3710DDCR pinout, TPS3710DDCR application, or TPS3710DDCR equivalent, this page delivers verified electrical specifications, SOT-23-THIN (DDC) package mapping, functional truth table behavior, thermal derating data, and automotive AEC-Q100 Grade 1 compliance context - all confirmed against TI's SBVS271A production datasheet.

Technical Context

The TPS3710DDCR integrates a high-accuracy comparator with a trimmed 400mV internal reference and built-in 5.5mV typical hysteresis to reject noise-induced false triggering. Its SENSE pin accepts input voltages up to 6.5V independent of VDD, enabling monitoring of rails higher than its own supply.

It operates across –40°C to +125°C junction temperature, supports undervoltage lockout (UVLO) at 1.3V–1.7V, and features a 150µs start-up delay after VDD exceeds 1.8V. The open-drain OUT pin sinks up to 40mA and tolerates pull-up voltages up to 18V, decoupled from VDD rail selection.

FAQ

What is the maximum input voltage the SENSE pin of the TPS3710DDCR can tolerate?

The SENSE pin of the TPS3710DDCR accepts voltages from 0V to 6.5V, independent of the VDD supply voltage. This allows monitoring of rails higher than VDD (e.g., 12V rail while VDD = 3.3V) using an external resistor divider. Absolute maximum rating for SENSE is 7V, per Section 5.1 of the SBVS271A datasheet. Exceeding 6.5V risks violating recommended operating conditions and may impact long-term reliability of the TPS3710DDCR.

Does the TPS3710DDCR require an external hysteresis network?

No, the TPS3710DDCR includes built-in hysteresis of 5.5mV typical (5.5–12mV over temperature), eliminating the need for external resistors. This internal hysteresis stabilizes the output against noise on the monitored rail and prevents oscillation during slow-moving undervoltage transitions. The TPS3710DDCR truth table and timing diagrams in Section 6.1 confirm that hysteresis is intrinsic to the comparator architecture - a key differentiator from basic reset ICs requiring external components.

Can the TPS3710DDCR's OUT pin be pulled up to a voltage higher than its VDD supply?

Yes, the TPS3710DDCR's open-drain OUT pin supports pull-up voltages up to 18V, regardless of the VDD supply voltage. For example, VDD may be 3.3V while OUT is pulled up to 12V to interface with a 12V-enable input on a DC-DC controller. This capability is explicitly specified in Section 5.3 (VO: 0–18V) and validated in Figure 7-1 of the SBVS271A datasheet - a critical feature enabling flexible system-level voltage translation without additional level-shifters in the TPS3710DDCR design.

What is the start-up behavior of the TPS3710DDCR after power application?

The TPS3710DDCR requires VDD to exceed 1.8V for at least 150µs before the output enters a valid state - this is the td(start) parameter defined in Section 5.6. During this interval, OUT remains asserted (low) if VDD is between V(POR) = 0.8V and UVLO = 1.7V, and undefined if VDD < 0.8V. Once stable, the device begins comparing SENSE voltage against VIT+ and VIT– thresholds. This controlled start-up ensures reliable reset assertion in systems with slow-ramping supplies, a behavior confirmed in Section 6.4.1 and Figure 5-1 of the TPS3710DDCR datasheet.

Is the TPS3710DDCR pin-compatible with other members of the TPS37xx family?

No, the TPS3710DDCR is not pin-compatible with other TPS37xx variants such as TPS3700 or TPS3701. While all share the same SOT-23-THIN (DDC) package footprint, pin assignments differ: TPS3710DDCR uses GND on pins 2/4/6, whereas TPS3700 places GND only on pin 2 and assigns different functions to pins 4 and 6. This mismatch is documented in TI's separate pin configuration tables for each part number. Substituting without board revision will cause functional failure - the TPS3710DDCR must be used with its specific pinout as shown in Figure 4-1 of SBVS271A.
