Product details

Active high and active low resets in one package

Having both reset polarities on the same device saves a logic inverter or level shifter on the board. The open-drain option allows wired-OR connections for shared reset lines, while push-pull eliminates the external pull-up resistor. This is a practical advantage in dense designs where every passive counts toward the BOM line count.

ROHS3 compliant. For procurement teams qualifying this part into a new BOM, there is no last-time-buy clock ticking.

Frequently asked questions

What is the reset timeout of TPS37B010122DSKR?

The reset timeout is 100µs maximum. This is a fast timeout, designed to let the system recover quickly after a voltage excursion while still filtering short glitches.

Does TPS37B010122DSKR have active high or active low reset?

It provides both active-high and active-low reset outputs. Each output can be independently configured as open drain or push-pull, giving flexibility to interface with different reset logic on the supervised ICs.

What are the equivalent parts or cross references for TPS37B010122DSKR?

The TLV803EA29VDBZR and TLV803ED29DBZR are simple reset/power-on reset devices with active-low, open-drain outputs, but they are single-channel supervisors with different threshold voltages (2.93V) and longer reset timeouts (130ms and 33ms respectively). They are not pin-compatible or threshold-equivalent to the TPS37B010122DSKR's dual 0.8V window supervision. For a functional match, stay within the TPS37 family.
