Product Overview
The TPS3711 is a Texas Instruments 36-V voltage detector for Power_Management designs requiring undervoltage detection. Its monitored threshold is set externally through a resistor divider into the SENSE comparator input, supporting monitored voltages down to a 400 mV threshold level. The device operates across a 1.8 to 36 V supply range and includes internal comparator hysteresis of 5.5 mV typical.
The output is open drain for undervoltage indication. OUT is low when SENSE is below VIT- and high impedance when SENSE is above VIT+, allowing the output to be pulled up within the specified 0 to 25 V output voltage range. Recommended output pin current is 0 to 10 mA, with low-level output voltage specified at 130 mV typical for 3 mA at VDD = 1.8 V and 150 mV typical for 5 mA at VDD = 5 V.
The part is offered in a SOT-6 package, DDC 6-pin, with a 2.90 mm × 1.60 mm body size. A 0.1-µF ceramic capacitor close to VDD is recommended for decoupling. The specified operating junction temperature range is -40 to 125 °C.

Procurement Notes
When requesting a quote for TPS3711, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For power IC and power device sourcing, voltage rating, current rating, power dissipation, package thermal performance, protection features, qualification grade and application conditions should be reviewed before approval.
FAQ
What supply range does the TPS3711 support?
The TPS3711 operates from a 1.8 to 36 V supply range. Its VDD absolute maximum rating is -0.3 to 40 V over the operating junction temperature range.
How is the TPS3711 monitored voltage threshold set?
The monitored voltage is applied to the SENSE comparator input through an external resistor divider. The adjustable monitored threshold can be set down to 400 mV.
What happens at the TPS3711 OUT pin during undervoltage?
The OUT pin is low when SENSE is below VIT-. When SENSE rises above VIT+, OUT becomes high impedance, allowing use with an external pullup within the specified output range.
What package is used for the TPS3711?
The TPS3711 is supplied in a SOT-6 package. The listed package case is a 6-pin SOT DDC package with a 2.90 mm × 1.60 mm body size.
