5引脚微处理器监控电路，带有看门狗和手动复位 5-Pin レP Supervisory Circuits with Watchdog and Manual Reset

General Description

The MAX6316–MAX6322 family of microprocessor µP supervisory circuits monitors power supplies and microprocessor activity in digital systems. It offers several combinations of push/pull, open-drain, and bidirectional such as Motorola 68HC11 reset outputs, along with watchdog and manual-reset features. The Selector Guide below lists the specific functions available from each device. These devices are specifically designed to ignore fast negative transients on VCC. Resets are guaranteed valid for VCC down to 1V.
