Supervisor with a 1.575 V threshold for low-voltage rails
The MAX6746KA16+T is a single-channel voltage supervisor from Analog Devices, monitoring a 1.575 V threshold with an active-low, push-pull reset output. It belongs to the Simple Reset/Power-On Reset family, designed to hold a microcontroller or processor in reset until the supply rail stabilises above the threshold, then release after an adjustable timeout period. The 1.575 V threshold targets low-voltage core rails, common in modern MCUs and SoCs operating at 1.8 V or 1.5 V nominal supplies. The adjustable timeout lets the designer match the reset hold time to the specific power-up ramp of the system — a critical parameter when the processor's POR circuit needs a clean release after all supply domains are within tolerance.
Industrial temperature grade and SOT-23-8 footprint
This makes it suitable for deployment in motor drives, outdoor telecom equipment, and automotive engine-bay applications where the ambient temperature exceeds the commercial 85°C ceiling. The SOT-23-8 package (supplier device package SOT-23-8) is a compact surface-mount footprint, 2.9 mm × 1.6 mm typical. The push-pull output eliminates the need for an external pull-up resistor, saving a component and a PCB trace on the reset line.
