What are the key features of MAX6412UK29+?
- Capacitor-adjustable reset timeout delay allows designers to set hold-off periods from microseconds to seconds with a single external capacitor
- Manual reset input (MNL RST) provides a dedicated pin for push-button or supervisory circuit-initiated resets
- Low-power design consumes minimal quiescent current, extending battery life in portable and energy-harvesting applications
- Compact 5-pin SOT-23 package occupies less than 3 mm² of PCB area for space-constrained microcontroller reset circuits
What is MAX6412UK29+ used for?
The MAX6412UK29+ is suited for microcontroller power-on reset and brownout protection in battery-powered IoT nodes, wearables, and industrial sensor modules where accurate voltage supervision at a 2.93 V threshold ensures the processor stays in reset until the supply is fully stable. Its programmable reset timeout via external capacitor enables customized startup sequencing in multi-rail embedded systems. The SOT-23 package and low quiescent current make it an efficient supervisor choice for space-constrained PCBs that must minimize idle power drain.

Frequently Asked Questions
How is the reset timeout delay adjusted in the MAX6412UK29+, and what range of delay times is achievable?
The MAX6412UK29+ uses a single external capacitor connected to its timing pin to set the reset timeout delay. By selecting capacitors from 1 nF to several microfarads, designers can program delay periods ranging from approximately 1 ms to over 1 second, enabling precise control of processor startup sequencing after power-on or brownout recovery.
What voltage threshold does the MAX6412UK29+ monitor, and how accurate is its detection?
The MAX6412UK29+ monitors a nominal 2.93 V reset threshold, with a tight factory-trimmed accuracy of approximately ±1.5% to ±2%, meaning the reset asserts when the supply drops below roughly 2.88 V to 2.98 V. This precision protects 3 V microcontrollers from executing code during undervoltage conditions that could corrupt flash memory or EEPROM writes.
What does the manual reset input on the MAX6412UK29+ allow system designers to implement?
The active-low manual reset input allows a push-button switch or an external supervisory signal to assert the reset output independently of supply voltage, holding the microprocessor in reset for the full programmed timeout delay after the button is released. This is essential in industrial controllers and medical instruments that require operator-initiated or watchdog-triggered processor restarts.
How does the MAX6412UK29+ compare to a discrete resistor-capacitor reset network for microcontroller reset generation?
Unlike a discrete RC network, which provides a poorly defined reset threshold that drifts with temperature and component tolerances by up to ±20%, the MAX6412UK29+ offers a factory-trimmed 2.93 V threshold accurate to within ±2%, guaranteed reset assertion during fast supply dropouts as short as 1 µs, and a standardized 5-pin SOT-23 footprint that simplifies PCB design and component qualification.
