What the MAX6838XSD2+T is and where it fits
The MAX6838XSD2+T from Maxim Integrated is a simple reset/power-on reset IC that monitors a single voltage rail and asserts a reset signal when the supply drops below a user-selectable threshold. The output is active-low push-pull, which means it pulls the reset line low during a fault and drives it high again once the supply is stable and the 20ms minimum timeout expires. This part is designed for surface-mount assembly in the compact SC-70-4 package, making it a fit for space-constrained boards in industrial control, telecom, and embedded systems where a reliable power-on reset is needed.
Temperature range and operating environment
Rated for -40°C to 85°C ambient, the MAX6838XSD2+T covers the industrial temperature grade. That spans factory-floor enclosures, outdoor telecom cabinets, and engine-bay-adjacent electronics where the board sees thermal cycling but not the full military range. The SC-70-4 package is small enough to fit on a cramped PCB alongside an MCU or FPGA that needs a clean reset signal at power-up.
Lifecycle and sourcing posture
The MAX6838XSD2+T carries an active lifecycle status and is ROHS3 compliant. There is no end-of-life notice or last-time-buy window to manage. For BOM planning, this part is available through independent distribution and is sourced to order against an RFQ.
