Texas Instruments TPS3710DSER

Overview

TPS3710DSER from Texas Instruments is a wide-input-voltage (1.8V–18V) precision voltage detector IC with 400mV internal reference, ±1.0% over-temperature threshold accuracy, 5.5µA typical quiescent current, open-drain 18V-rated output, and built-in 5.5mV hysteresis - used for reliable power-on reset and undervoltage monitoring in automotive and industrial control systems.

For engineers reviewing the TPS3710DSER datasheet, TPS3710DSER pinout, TPS3710DSER application, or TPS3710DSER equivalent, this page delivers verified package mapping (WSON-6), confirmed SENSE/OUT/GND/VDD terminal roles, real-world timing (150µs start-up delay, 18µs high-to-low propagation), automotive-grade AEC-Q100 qualification, and design-meaningful parameter context - all extracted from TI's SBVS271A production data sheet.

Technical Context

The TPS3710DSER implements a high-accuracy comparator with trimmed 400mV internal reference and fixed 5.5mV hysteresis, enabling stable detection of monitored rail drops below VIT− (e.g., 394.5mV min at −40°C to +125°C). Its SENSE pin accepts input up to 6.5V independent of VDD, supporting monitoring of rails higher than its supply via external resistor dividers.

It operates in three functional modes: normal operation above 1.8V VDD with 150µs start-up delay; undervoltage lockout (UVLO) between 1.3V–1.7V where OUT is forced low; and undefined output state below 0.8V power-on reset (POR) threshold. The open-drain OUT sinks up to 40mA and supports pull-up to 18V regardless of VDD level.

FAQ

What is the exact package type and footprint for TPS3710DSER?

The TPS3710DSER uses the WSON-6 (DSE) package with 1.5mm × 1.5mm body size and wettable flank leads. It has six terminals: GND (pins 1, 3, 5), OUT (pin 6), SENSE (pin 4), and VDD (pin 2). This package is distinct from the SOT-23-6 (DDC) variant and requires specific land pattern dimensions per TI's SLVU129B mechanical drawing.

Does TPS3710DSER support monitoring voltages higher than its VDD supply?

Yes, the TPS3710DSER supports monitoring rails higher than its VDD supply - the SENSE pin accepts up to 6.5V regardless of VDD level. For example, with VDD = 3.3V, you can monitor a 12V rail using an external resistor divider. This capability is explicitly confirmed in Section 7.1.3 of the SBVS271A datasheet and enables flexible multi-rail supervision without additional level shifters.

What is the minimum recommended pull-up voltage for the open-drain OUT pin of TPS3710DSER?

The TPS3710DSER OUT pin supports pull-up voltages up to 18V, independent of VDD. There is no minimum pull-up voltage specified - however, to ensure reliable logic-high assertion, the pull-up must exceed the system's input high threshold (e.g., ≥2.0V for 3.3V CMOS). TI recommends selecting RP such that (VPULLUP − Ilkg(OD) × RP) > VOH(min) - with Ilkg(OD) ≤300nA per datasheet Section 5.5.

Is TPS3710DSER qualified for automotive applications, and what does that entail?

Yes, the TPS3710DSER is AEC-Q100 qualified as Grade 1 (−40°C to +125°C ambient), with HBM ESD rating of ±2.5kV and CDM rating of ±1kV. This qualification covers stress testing across temperature, humidity, vibration, and electrical robustness - confirming suitability for under-hood automotive ECUs, ADAS modules, and infotainment systems per ISO/TS 16949 requirements.

How does the internal hysteresis of TPS3710DSER improve system reliability?

The TPS3710DSER integrates 5.5mV typical hysteresis (VIT+ − VIT−) to prevent output oscillation during slow or noisy rail transitions. This eliminates the need for external RC networks while rejecting transients as short as ~2.5µs (per Figure 5-7). In practice, this ensures clean reset assertion during brownouts - a critical feature for microcontrollers and FPGAs where false resets cause system lockup or data corruption.
