Product details

What this supervisor does on the rail

The push-pull output drives the reset line directly; no external pull-up resistor is needed. That saves one component per supervisor channel on the BOM and frees a trace routing lane on dense automotive PCBs. It can sit on the same board as a motor-drive gate driver or an isolated DC-DC converter without derating concerns.

Package and mounting — SOT-23-5 footprint

Housed in a 5-pin SOT-23-5, this supervisor takes up roughly the same board area as a small-signal transistor. Surface-mount assembly is standard; the small footprint leaves room for the passives around the monitored rail.

Sourcing and lifecycle — no LTB pressure

There is no last-time-buy window approaching, no NRND flag, and no PCN-driven scramble. ROHS3 compliance is confirmed, so it passes the materials declarations for export into EU and UK markets without an exemption review.

Frequently asked questions

What is the reset timeout for TPS3823-33QDBVRQ1?

The reset timeout is 120ms minimum. After the supply rises above the 2.93V threshold, the part holds the reset line low for at least 120ms before releasing it, giving the downstream processor time to stabilize.

Is TPS3823-33QDBVRQ1 suitable for automotive applications?

Yes, it is part of the Automotive, AEC-Q100 series and rated for -40°C to 125°C operating temperature, making it suitable for under-hood and engine-bay environments.

What are alternatives to TPS3823-33QDBVRQ1?

A functional alternative is the TLV803EA29VDBZR, which is also a simple reset/power-on reset with active-low output, but uses an open-drain output instead of push-pull. The TLV803ED29DBZR has a shorter 33ms minimum reset timeout. Both are AEC-Q100 qualified and operate from -40°C to 125°C, but the open-drain output requires an external pull-up resistor on the reset line.
