AEC-Q100 qualification means this part has passed stress tests required for automotive tier-1 PPAP submissions. The lifecycle status is active, so there is no LTB or end-of-life risk for current designs.
Housed in a SOT-23-5 surface-mount package, the MAX6756UKTD0+ takes minimal board area and is compatible with standard reflow profiles. The bulk shipping option means it arrives in a tube or tray, not tape-and-reel.
Yes, the reset output is active low and open drain, so it pulls low when the monitored voltage drops below the threshold. An external pull-up resistor to the logic supply is required.
The MAX809 is a pin-compatible supervisor with the same 3.3V threshold, active-low open-drain output, and SOT-23-5 package. The key difference is the reset timeout: the MAX6756UKTD0+ has a 20µs typical timeout, while the MAX809 typically has a 140ms minimum timeout. Choose the MAX809 if your system needs a longer reset hold time; the MAX6756UKTD0+ is better for fast recovery from brownout events.
The reset timeout is 20µs typical. This short timeout means the reset releases quickly once the supply returns above the threshold — suitable for applications where the supervisor must not delay system startup.
Yes, it is AEC-Q100 qualified, making it suitable for automotive applications that require PPAP documentation and extended reliability testing.
