Product Summary

  • The TPS3808G33DBVR is a Low Quiescent Current, Programmable-Delay Supervisory Circuit. It voltages from 0.4V to 5.0V, asserting an open drain RESET signal when the SENSE voltage drops below a preset threshold or when the manual reset (MR) pin drops to a logic low. The TPS3808G33DBVR uses a precision reference to achieve 0.5% threshold accuracy for VIT ≤ 3.3V. It has a very low typical quiescent current of 2.4mA so it is well-suited to battery-powered applications. The TPS3808G33DBVR is available in a small SOT23 and an ultra-small 2mm × 2mm QFN PowerPAD package and is fully specified over a temperature range of –40℃ to +125℃ (TJ).
