MAX6887 - Power-Supply Supervisory

Description

The MAX6887/MAX6888 multivoltage supply supervisors provide several voltage-detector inputs, one watchdog input, and three outputs.

Each voltage-detector input offers a factory-set undervoltage and overvoltage threshold.

Manual reset and margin disable inputs offer additional flexibility.

19-0291; Rev 2; 2/10 Hex/Quad, Power-Supply Supervisory Circuits MAX6887/MAX6888 General Description The MAX6887/MAX6888 multivoltage supply supervisors provide several voltage-detector inputs, one watchdog input, and three outputs. Each voltage-detector input offers a factory-set undervoltage and overvoltage threshold. Manual reset and margin disable inputs offer additional flexibility. The MAX6887 offers six voltage-detector inputs, while the MAX6888 offers four inputs. Output RESET asserts when any input voltage drops below its respective undervoltage threshold or manual reset MR is asserted. Output OV asserts when any input voltage exceeds its respective overvoltage threshold. Monitor standard supply voltages listed in the Selector Guide.
