Frequently Asked Questions
At what supply voltage does MAX6467US22D3+ assert its RESET output, and how accurate is that threshold?
MAX6467US22D3+ asserts the active-low RESET output when the monitored supply drops below a fixed 2.2 V threshold. Maxim specifies the threshold accuracy at ±2% across temperature, meaning the actual trip point falls between 2.156 V and 2.244 V, which is tight enough for reliable under-voltage lockout in 2.5 V and 2.8 V supply rail applications without an external voltage divider.
How does the edge-triggered one-shot manual reset feature work in MAX6467US22D3+, and why is it important for user-accessible reset buttons?
When the manual reset pin (MR) receives a falling edge, MAX6467US22D3+ generates a fixed-duration active-low reset pulse — typically 140 ms — regardless of how long the button is held. This one-shot behavior debounces the mechanical switch and ensures the microprocessor receives a single clean reset pulse, preventing multiple resets from contact bounce on a 3.3 V or 5 V reset button line.
How does MAX6467US22D3+ compare to a discrete RC reset circuit in terms of threshold accuracy and reset-pulse consistency?
A discrete RC reset circuit has a time constant that varies with resistor and capacitor tolerances, typically ±20%, and its trip voltage depends on the MCU's reset-pin threshold, which can span 0.8 V to 2 V. MAX6467US22D3+ provides a factory-trimmed ±2% threshold at 2.2 V and a guaranteed minimum reset pulse of 140 ms, delivering consistent behavior across production lots and temperature ranges from -40°C to +85°C without manual calibration.
Does MAX6467US22D3+ fit legacy 5 V microprocessor designs, or is it limited to low-voltage systems?
MAX6467US22D3+ is specified to operate with VCC supplies ranging from the monitored threshold up to 5.5 V, so it can supervise 3.3 V, 2.5 V, or 2.2 V rails while the device itself is powered from a higher rail. Its RESET output is open-drain, which allows the output to be pulled up to 5 V logic levels, making it compatible with both legacy 5 V and modern 3.3 V microprocessors in mixed-voltage designs.
