Product Summary
The TPS3808G18DBVR is a Low Quiescent Current, Programmable-Delay Supervisory Circuit. It uses a precision reference to achieve 0.5% threshold accuracy for VIT ≤ 3.3V. The TPS3808G18DBVR has a very low typical quiescent current of 2.4mA so it is well-suited to battery-powered applications. The TPS3808G18DBVR 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).
