The open-drain output lets multiple supervisors share a common pull-up resistor, or wire-OR with another reset source, without contention — a common topology on multi-rail boards where the FPGA and MCU reset chains converge. ## Active production — RoHS non-compliant Note the RoHS non-compliant marking — this part uses lead-bearing solder (tin-lead) on the leads, which is acceptable in military, aerospace, and certain industrial applications that have a RoHS exemption, but it will not pass a standard RoHS inspection.","metaTitle":"MAX817LEPA Battery Backup Circuit, 4.65V Threshold, 8-PDIP","metaDescription":"MAX817LEPA supervisor IC with battery backup, active-low reset, 140ms timeout. 4.65V threshold, -40°C to 85°C. 8-PDIP.
