Procurement Notes
When requesting a quote for TPS3801, 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 type of device is the TPS3801?
The TPS3801 is a Texas Instruments supply voltage supervisor with a push-pull RESET output. Depending on version, it monitors either an adjustable SENSE input or a fixed VDD threshold.
What reset recovery delay does TPS3801 provide?
The TPS3801 family has a 200 ms typical factory-programmed reset recovery delay after the monitored voltage returns above threshold. Under stated test conditions, the delay is specified as 120 ms minimum, 200 ms typical, and 280 ms maximum.
Which TPS3801 variants include manual reset input?
Manual reset input is included on TPS3801 variants except TPS3801-01. A low level at MR causes RESET to become active, and the functional block diagram shows an internal MR pull-up resistance of 30 kΩ.
What package is specified for TPS3801?
The TPS3801 is specified in a 5-pin SC-70 (SOT-323), DCK package. Orderable DCKR parts are listed with 3000 quantity on large tape and reel and NIPDAU lead finish/ball material.
