Texas Instruments TPS3710DSET

Overview

TPS3710DSET from Texas Instruments is a wide-input-voltage precision voltage detector IC used for system-level power monitoring and reset assertion in automotive and industrial applications. It operates from 1.8V to 18V supply, features a 400mV internal reference with ±1.0% over-temperature accuracy, 5.5µA typical quiescent current, open-drain 18V-rated output, and built-in 5.5mV hysteresis.

For engineers reviewing the TPS3710DSET datasheet, TPS3710DSET pinout, TPS3710DSET application, or TPS3710DSET equivalent, this page delivers verified technical context, package-specific pin functions, real-world use cases, and validated alternative options for voltage supervision in high-reliability embedded systems.

Technical Context

The TPS3710DSET integrates a high-accuracy comparator with a trimmed 400mV internal reference and programmable threshold via external resistor divider on the SENSE pin. Its input supports up to 6.5V independent of VDD, enabling monitoring of rails higher than its own supply.

It implements undervoltage lockout (UVLO) at 1.3–1.7V and power-on reset (POR) below 0.8V, with 150µs start-up delay and propagation delays of 18µs (HL) / 29µs (LH). The open-drain output sinks up to 40mA and tolerates pullup voltages up to 18V, decoupled from VDD.

FAQ

What is the maximum voltage that can be applied to the SENSE pin of the TPS3710DSET?

The SENSE pin of the TPS3710DSET accepts voltages from 0V to 6.5V, independent of the VDD supply voltage. This allows monitoring of higher-voltage rails (e.g., 12V or 24V) using an external resistor divider. Exceeding 6.5V on SENSE risks damage, even if VDD is within its 1.8–18V range. Always verify divider ratio and worst-case rail tolerance to ensure SENSE stays within spec.

Does the TPS3710DSET require an external capacitor on the SENSE pin?

The TPS3710DSET does not require an external capacitor on the SENSE pin for basic operation. However, for extremely noisy environments-such as automotive power rails with switching transients-a 1nF to 10nF bypass capacitor from SENSE to GND is recommended to reduce sensitivity to fast transients. This improves immunity without affecting threshold accuracy or response time.

Can the TPS3710DSET output drive a 3.3V logic reset input directly?

Yes, the TPS3710DSET output can drive a 3.3V logic reset input. Its open-drain output is rated to 18V and requires an external pullup resistor. To interface with a 3.3V reset input, connect the pullup resistor to a 3.3V rail. The TPS3710DSET will sink current when asserted (low), pulling the line to <250mV, satisfying standard logic-low requirements for most 3.3V devices.

What is the purpose of the 150µs start-up delay (t_d(start)) in the TPS3710DSET?

The 150µs start-up delay ensures the TPS3710DSET output remains undefined until VDD has stabilized above 1.8V for at least 150µs. This prevents premature or metastable reset assertion during power ramp-up. After this delay, the device begins monitoring the SENSE pin and asserts OUT only when valid threshold conditions are met-critical for reliable power-on sequencing in microcontrollers and FPGAs.

Is the TPS3710DSET pin-compatible with other members of the TPS37xx family?

The TPS3710DSET shares the same 6-pin WSON (DSE) package and pinout with other TPS37xx variants like TPS3700 and TPS3701. However, threshold accuracy, supply range, and hysteresis differ across the family. While physical layout is compatible, electrical behavior-including VIT accuracy (±1.0% vs ±2.5%) and UVLO levels-is not interchangeable without validation. Always consult the specific datasheet for each variant.
