TPS3850G18DRCT

Supervisors Overview

The TPS3850G18DRCT is a precision voltage supervisor from Texas Instruments designed for overvoltage and undervoltage detection. It operates within a supply voltage range of 1.6 V to 6.5 V with a fixed threshold of 1.8 V. The device features an active low, open-drain output and includes a built-in watchdog timer. Reset delay is fixed at 200 ms, with accuracy specified at 0.8%. It consumes 10 uA of quiescent current and functions between -40°C and +125°C. Packaged in a VSON-10 surface-mount case.

Supervisors Feature Summary

• Provides precise monitoring for overvoltage and undervoltage conditions on a single input channel.
• Integrates a watchdog timer to detect software faults or system hangs.
• Delivers an active low reset signal via an open-drain output interface.

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Battery-powered systems needing low standby current
• Embedded controllers requiring reliable voltage supervision

Supervisors Procurement Notes

Verify the specific suffix DRCT confirms the reel packaging format when ordering. Ensure the G18 designation matches the required 1.8 V threshold for your circuit design. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 1.8 V threshold is required for single-input supervision. Consider the VSON-10 package constraints for board layout. Evaluate the 10 uA quiescent current against system power budgets. Verify that the 200 ms fixed reset delay meets timing requirements for connected loads.

Supervisors Part Context
