MAX6884ETP+

The MAX6884ETP+ is an EEPROM programmable, hex power supply supervisory circuit in 20 pin TQFN package. This multivoltage supervisor monitors six voltage detector inputs, one auxiliary input and one watchdog input. It has three programmable outputs for highly configurable power supply monitoring applications. Each voltage detector input offers programmable primary undervoltage and secondary undervoltage/overvoltage threshold. Programmable output options include open-drain or weak pull-up. An internal 10bit, 1% accurate ADC converts voltages at IN1–IN6, AUXIN and VCC through multiplexer that automatically sequences through all inputs every 200ms. A SMBus/I2C compatible serial data interface programs and communicates with configuration EEPROM, configuration registers, EEPROM and reads ADC registers and fault registers. It is used in telecommunications/central office systems, networking systems, servers/workstations, base stations, storage equipment & multimicroprocessor/voltage systems.
