MAX6390XS29D4+ Analog Devices Integrated Circuit (Other) In Stock
MAX6390XS29D4+ is a low-voltage, low-power microprocessor reset supervisor from Analog Devices in a tiny 4-pin SC-70 package. It monitors supply voltage with a fixed 2.93 V threshold and issues a reset pulse to keep microcontrollers in a safe state during power-up and brownout events. Designed for portable devices, embedded systems, and any application requiring reliable processor reset with minimal quiescent current.

What is MAX6390XS29D4+ used for?
MAX6390XS29D4+ is used in portable consumer electronics, IoT sensor nodes, and handheld instruments to ensure reliable microcontroller startup and brownout recovery. The fixed 2.93 V threshold suits 3.3 V regulated rails common in ARM and PIC-based designs. Its tiny SC-70 footprint makes it the preferred choice for space-limited PCBs where a discrete reset circuit would consume unacceptable board area.

Frequently Asked Questions
At what supply voltage does MAX6390XS29D4+ assert its reset output, and why is that threshold relevant for 3.3 V systems?
MAX6390XS29D4+ asserts the active-low RESET output when VCC falls below its fixed 2.93 V threshold. This gives a 370 mV margin below the nominal 3.3 V rail, catching brownout conditions early enough for a microcontroller to halt cleanly before reaching its own minimum operating voltage, typically around 1.8 V to 2.7 V.
How does the 4-pin SC-70 package of MAX6390XS29D4+ compare to SO-8 reset supervisors in board area?
The SC-70 package body is approximately 2.0 mm x 1.25 mm, roughly 4 times smaller than an SO-8 package body of 4.9 mm x 3.9 mm. For designs with 4 pins or fewer needed on the supervisor, this reduction is significant in densely routed PCBs near microcontroller reset pins.
Which microcontroller families pair well with MAX6390XS29D4+ for reliable system startup in portable products?
MAX6390XS29D4+ works with any microcontroller that accepts an active-low reset signal and operates from a 3.3 V rail, including STM32 Cortex-M0/M3 devices, PIC16/PIC18 families, and MSP430 series. Its single-channel supervision covers the main core supply, and the SC-70 package can be placed within 5 mm to 10 mm of the MCU reset pin to minimize noise coupling.
