It is designed for systems that need reliable power-up sequencing and brownout protection across multiple voltage domains — common in automotive ECUs, industrial controllers, and base station line cards where a single supervisor must watch both a core rail and an I/O rail. The reset output is active high with a push-pull, totem-pole stage, so it drives the reset input of an MCU or FPGA directly without an external pull-up. The minimum reset timeout of 140 ms gives the downstream device enough time to stabilize after the monitored rails cross the threshold. One channel has a fixed threshold of 1.67 V, the other is adjustable via an external resistor divider.
The SOT-23-6 package is small enough to fit tight layouts but still hand-reworkable with a hot-air station. No hidden thermal pad means you can lift the part cleanly without cooking the board — just preheat the area, apply flux, and lift with tweezers once the solder flows. That matters when you are swapping a supervisor on a prototype or repairing a field-return board.
It can sit under the hood in an engine control module or on a motor-drive board next to hot MOSFETs. The wide range also covers industrial outdoor gear and telecom cabinets that see freeze-thaw cycles.
Note that this variant is marked RoHS non-compliant. If your BOM requires RoHS compliance, verify the lead-free suffix before ordering.
