Product details

What this supervisor does and who specifies it

The TPS3851H30EDRBT is a Simple Reset/Power-On Reset IC from Texas Instruments — a single-channel voltage supervisor that monitors a 3V rail and asserts an Active Low, Open Drain reset output when the supply drops below threshold. The 170ms minimum reset timeout holds the system in reset long enough for the core supply to stabilise before the processor or FPGA boots.

Package and footprint — 8-SON with exposed pad

Surface-mount assembly; the 0.50 mm pitch is manageable on a 2-layer board if the thermal pad is stitched to the ground plane with enough vias.

Frequently asked questions

What is the reset threshold of TPS3851H30EDRBT?

The voltage threshold is 3V. The reset output (Active Low, Open Drain) asserts when the monitored rail falls below this level and releases after the 170ms minimum reset timeout.

What is the closest functional second-source to TPS3851H30EDRBT?

The TLV803EA29VDBZR is a peer Simple Reset/Power-On Reset with Active Low, Open Drain output, but its reset timeout is 130ms minimum and its threshold is 2.93V (not 3V). The TLV803ED29DBZR has a 33ms minimum timeout. Neither is a drop-in replacement — the threshold and timeout differences must be verified against the system timing budget.
