MAX6887EETE+

The MAX6887EETE+ is a hex power supply supervisory circuit in 16 pin TQFN package. This multivoltage supply supervisor monitors standard supply voltages, 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 undervoltage and overvoltage thresholds are factory-set for monitoring standard supply voltages. It offers six voltage detector inputs, output RESET (complementary) asserts when any input voltage drops below its respective undervoltage threshold or manual reset MR (complementary) is asserted. Output OV (complementary) asserts when any input voltage exceeds its respective overvoltage threshold. It offers a watchdog timer with an initial and normal timeout periods of 102.4s and 1.6s respectively. It is used in multivoltage systems, telecom, servers/workstations/storage systems and networking.

• Supply voltage range is 2.7V to 5.8V, Supply current of 1.2mA (max)
• Operating temperature range from -40°C to 85°C
• Threshold accuracy of 1%
• Margining disable and manual reset input
• Open-drain RESET (complementary), OV (complementary) and WDO(complementary) outputs
• Threshold hysteresis is 0.3% VTH, threshold tempco is 10ppm/°C
• Six nominal input voltage of 3.3V, 2.5V, 1.8V and 3 adjustable inputs with 5% tolerance
