TPS3851G50EDRBR

Supervisors Overview

The TPS3851G50EDRBR is a high-accuracy voltage supervisor manufactured by Texas Instruments. It features an open-drain or open-collector output and provides one monitored channel with a fixed threshold voltage of 5V. The device generates a low-active reset signal with a minimum timeout of 170ms. It operates within a temperature range of -40°C to 125°C (TJ) and is housed in an 8-SON (3x3) package with exposed pad.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for single-channel monitoring
• Features factory-programmed precision watchdog and reset timers
• Supports manual reset input via dedicated pin

Supervisors Applications

• Surround view system ECU
• General embedded system power supervision
• Industrial control unit monitoring

Supervisors Procurement Notes

Verify the specific suffix 'EDRBR' against the manufacturer datasheet to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure the 5V threshold aligns with the target supply rail requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 5V threshold is required for systems operating between 1.6V and 6.5V. Consider the 8-SON package size for space-constrained designs. Verify that the open-drain output capability matches the pull-up requirements of the connected microcontroller or logic interface.

Supervisors Part Context

This part belongs to the TPS3851 family of high-accuracy voltage supervisors from Texas Instruments. The family includes variants with different thresholds and automotive qualifications, such as the TPS3851-Q1 series. The TPS3851G50EDRBR represents the standard industrial-grade version with a 5V threshold.

Supervisors Replacement Considerations

TPS3851G50EDRBT is a parameter-equivalent alternative available in cut-tape packaging.
