TPS3806I33DBVT

Supervisors Overview

The TPS3806I33DBVT is a dual-input voltage detector from Texas Instruments, housed in an SOT-23-6 package. It operates within a supply voltage range of 1.6 V to 6 V with a quiescent current of 3 uA. The device features adjustable under-voltage and over-voltage thresholds, specifically set at 3 V for undervoltage and 1.216 V/3.022 V for overvoltage detection. It provides an active-low, open-drain output without manual reset or watchdog timer capabilities. Accuracy is specified at 2%, supporting operation between -40°C and +85°C.

Supervisors Feature Summary

• Dual-channel monitoring for independent input supervision
• Adjustable threshold settings for flexible voltage detection
• Ultra-low power consumption suitable for battery applications

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing reliable power management
• Embedded circuits with multiple voltage rails

Supervisors Procurement Notes

Verify the specific suffix DBVT corresponds to the cut tape packaging format when sourcing samples or small quantities. Confirm that the I33 designation aligns with the required temperature grade and threshold specifications for your design. Ensure compatibility with the SOT-23-6 footprint during PCB layout. Cross-reference the manufacturer's latest datasheet for any updates on recommended operating conditions.

Supervisors Selection Notes

Choose this component when dual-input supervision is necessary without the complexity of a watchdog timer. The adjustable thresholds allow adaptation to various system voltages within the 1.6 V to 6 V range. Consider the 2% accuracy for precision requirements. The open-drain output requires external pull-up configuration. Evaluate the 3 uA quiescent current against total system power budgets.

Supervisors Part Context

Part of the TPS3806 series focusing on dual-input voltage detection. Differentiates from single-input supervisors like TPS3808 by offering two independent monitoring channels. Lacks manual reset and backup switch features found in other PMIC variants. Designed for cost-sensitive applications where dual supervision reduces component count.
