Product details

Supervisor for harsh environments — what the ratings mean

It monitors a 3.0V or 3.3V rail with a 2.64V threshold and asserts a reset output when the supply drops below that level. The reset output is Active Low with a push-pull, totem-pole stage — no external pull-up resistor needed, which simplifies the BOM on the processor reset line. The 120ms minimum reset timeout ensures the monitored rail has stabilised before the processor is released from reset — long enough to cover most power-supply ramp-up profiles.

The TPS3809L30MDBVREP is supplied in a SOT-23-3 package, a three-lead surface-mount footprint. The small body fits into compact designs, but the narrow lead spacing means the PCB land pattern should follow the manufacturer's recommended footprint to avoid solder bridging during reflow.

No stock-holding claim is made; the part is procured per RFQ.

Frequently asked questions

What is the reset timeout of TPS3809L30MDBVREP?

The reset timeout is 120ms minimum. This is the time the supervisor holds the reset line active after the monitored voltage rises above the threshold, ensuring the supply rail has stabilised before the processor starts executing code.

Can TPS3809L30MDBVREP replace TLV803EA29VDBZR?

The TPS3809L30MDBVREP and TLV803EA29VDBZR are both single-channel supervisors with Active Low reset, but they differ in output stage and temperature range. Check the output drive and temperature requirements of your design before substituting.
