MAX16050集成電路（IC）的電源控制器監(jiān)視器規(guī)格書(shū)PDF中文資料

General Description

The MAX16050 monitors up to 5 voltages and sequences up to 4 voltages, while the MAX16051 monitors up to 6 voltages and sequences up to 5 voltages. These devices provide an adjustable delay as each supply is turned on and they monitor each power-supply voltage, including the input voltage VCC. When all of the voltages reach their final values and the reset delay timer expires, a power-on-reset (RESET) output deasserts allowing the microcontroller (μC) to operate. If any voltage falls below its threshold, the reset output asserts and all voltage supplies are turned off. The MAX16050/MAX16051 can be daisy-chained to control a higher number of voltages in a system.
