Three-rail supervisor in a five-pin SC-70
It is designed for systems that need to sequence or protect multiple power domains — think FPGA core and I/O rails, mixed-signal boards with separate analog and digital supplies, or any multi-voltage embedded controller. The reset output is push-pull, totem pole, so it drives the reset line directly without an external pull-up.
Voltage thresholds and reset timing
The three monitored thresholds are 1.11 V, 3.075 V, and an adjustable input that lets you set a third rail voltage with an external resistor divider. The reset timeout is a minimum of 150 ms.
Package and temperature range
Housed in an SC-70-5 (also known as SOT-353), this is a five-lead surface-mount package that fits tight layouts. The supplier device package is SC-70-5, so verify your PCB footprint matches that standard.
