MAX16055HAUB+ IC SUPERVISOR 6 CHANNEL 10UMAX Analog Devices Inc./Maxim Integrated

 

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.
