MAX16165ATPH+

MAX16165 is a highly integrated, 4-channel sequencer and supervisor monitor for up to five voltages and sequences up to four voltages. This device provides an adjustable delay as each supply is turned on as well as monitor each power-supply voltage, including the input voltage VDD. The sequencing is enabled by two inputs, ON and OFF. A rising edge on the ON input initiates power-on sequencing of the channels whereas a falling edge on OFF input initiates power-off sequencing. During the power-on sequencing, when all of the voltages reach their final values, a sequencing done output DONE asserts high followed by a Power-OK (POK) output after the reset delay timer has expired, allowing the microcontroller to operate. Application includes latch-up prevention and inrush current protection in multi-supply systems, FPGA/ASIC power supply sequencing, servers and security cameras, test equipment, networking equipment, and industrial sensors and motor controls.
