Product Details
These devices feature adjustable reset and watchdog timeout using external capacitors. The MAX16056/MAX16058 contain a watchdog timer with a watchdog select input (WDS) that multiplies the watchdog timeout period by 128. The MAX16057/MAX16059 do not have the watchdog feature.
The MAX16056–MAX16059 are available in either push-pull or open-drain output-type configurations (see the Ordering Information in the full data sheet). These devices are fully specified over the -40°C to +125°C automotive temperature range. The MAX16056/MAX16058 are available in the 8-pin TDFN package, and the MAX16057/MAX16059 are available in the 6-pin TDFN package.
