onsemi MAX809
The MAX809 and MAX810 are cost−effective system supervisor circuits designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. The reset output is driven active within 10 msec of VCC falling through the reset voltage threshold. The MAX810 has an active−high RESET output while the MAX809 has an active−low RESET output.| Part No. | MAX809 |
