Product details

1.62 V threshold for 1.8 V rail monitoring

The TPS3124J18DBVR is a Texas Instruments Simple Reset/Power-On Reset IC with a voltage threshold of 1.62 V, purpose-set to monitor a 1.8 V supply rail with a 10% undervoltage window. The reset output is both active-high and active-low, driven by a push-pull totem-pole stage — no external pull-up resistor needed. This covers both processor reset polarities from a single device.

SOT-23-5 footprint and industrial temperature range

Housed in a SOT-23-5 package (SC-74A, SOT-753), surface-mount only. The single-voltage monitor is a dedicated supervisor — no extra channels, no watchdog. For a 1.8 V rail, this is the right threshold; for other voltages, the TPS3124 family offers variants with different trip points.

Frequently asked questions

Where can I buy TPS3124J18DBVR with stock in the USA?

No stock-holding claim; sourced per order.

What is the exact reset timeout of TPS3124J18DBVR?

The reset timeout is 100 ms minimum. The output holds the reset state for at least 100 ms after the monitored voltage rises above the 1.62 V threshold.

Can TPS3124J18DBVR be used to monitor a 1.8V rail?

Yes. The 1.62 V threshold is set for a 1.8 V supply with a 10% undervoltage tolerance. It asserts reset when the rail dips below 1.62 V.

Is TPS3124J18DBVR push-pull or open drain?

Push-pull, totem-pole output. Both active-high and active-low signals are driven — no external pull-up resistor required.
