2.2V threshold supervisor in a 1.05 mm² footprint
The MAX6407BS22: Packaged in a 4-bump WFBGA/CSPBGA (4-UCSP) measuring 1.05 x 1.05 mm, this supervisor fits into space-constrained designs where board area is at a premium.
20 µs propagation delay and industrial temperature range
With a typical propagation delay of 20 µs, the device responds quickly to a supply brownout, resetting the system before the core logic enters an undefined state. The active-high reset polarity means the output goes high when the supply is valid and pulls low on a fault — confirm this matches the reset input logic of the target processor before committing the BOM line.
Note that this part is listed as RoHS non-compliant, which may restrict its use in markets or applications requiring RoHS exemption-free assemblies.
