TPS3824-33DBVR

Supervisors Overview

The TPS3824-33DBVR is a voltage monitor circuit from Texas Instruments designed for supervising power supply voltages in electronic systems. It operates within a supply voltage range of 1.1 V to 5.5 V and features a fixed threshold voltage of 2.93 V with an accuracy of 2.4%. The device provides active high and active low push-pull outputs, ensuring reliable reset signaling. It includes a watchdog timer and offers a reset delay time of 200 ms. The component consumes a typical operating current of 15 uA and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system stability monitoring
• Provides dual active high and active low push-pull outputs
• Features a fixed detection threshold voltage for precise supervision
• Operates with low quiescent current consumption

Supervisors Applications

• DSP and processor-based system initialization
• Timing supervision for microcontroller units
• Battery-powered portable devices requiring low current
• Industrial control systems within specified temperature ranges

Supervisors Procurement Notes

Verify the specific suffix DBVR indicates the SOT-23-5 reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required output polarity and threshold voltage specifications for the target application design.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required for single-input voltage monitoring. The push-pull output architecture eliminates the need for external pull-up resistors. Consider the 200 ms reset delay and 15 uA current consumption against system power budgets and timing requirements during the design phase.

Supervisors Part Context

This part belongs to the TPS3824 series of simple reset supervisors. It is distinct from variants like TPS3823 or TPS3828 which may offer different output types such as open-drain or manual reset capabilities. The TPS3824 specifically focuses on providing both active high and low signals without manual intervention.

Supervisors Replacement Considerations

TPS3824-33DBVT is a tape-and-reel alternative with identical electrical characteristics but different physical packaging format.
