Dual-voltage supervisor with AEC-Q100 qualification
The MAX6762TARAD0 is a dual-voltage power supply monitor from Analog Devices, qualified to AEC-Q100 Grade 1 for automotive applications. It monitors two independent voltage rails with a threshold of 3V on one input and an adjustable threshold on the second, asserting an active-low reset when either rail falls below its threshold. The reset output is open-drain, allowing wired-OR connection with other reset sources in the system. Reset timeout is 20 µs typical, ensuring the downstream microcontroller or ASIC sees a clean, glitch-free reset pulse after the supply recovers.
Automotive temperature grade and package
The 8-WDFN exposed pad package (8-TDFN-EP 3x3 mm) provides a low thermal resistance path to the PCB ground plane, critical for maintaining junction temperature within limits during sustained operation in high-ambient environments. Surface-mount assembly with the exposed pad soldered to a thermal land on the PCB is required to achieve the rated thermal performance. The package is supplied in bulk, not tape-and-reel, which may affect pick-and-place feeder setup for high-volume lines.
No pin-compatible second-source or direct replacement is listed on the manufacturer's cross-reference.
