1 / 22 page General Description The MAX16050 monitors up to 5 voltages and sequences up to 4 voltages, while the MAX16051 moni- tors up to 6 voltages and sequences up to 5 voltages. These devices provide an adjustable delay as each sup- ply is turned on and they monitor each power-supply voltage. When all of the voltages reach their final values and the reset delay timer expires, a power-on-reset (POR) 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. During a power-down event, the MAX16050/MAX16051 can reverse sequence the outputs. In this situation, each voltage is turned off sequentially until it reaches a 250mV level, at which point, the next supply is turned off. The MAX16050/MAX16051 also provide internal pulldown cir- cuitry that turns on during power-down, to help dis- charge large output capacitors. The MAX16050/MAX16051 feature a charge-pump sup- ply output that can be used as a pullup voltage for dri- ving external n-channel MOSFETs and an overvoltage output that indicates when any of the monitored voltages exceeds its overvoltage threshold. The MAX16050 also provides three sequence control inputs for changing the sequence order, while the MAX16051 has a fixed sequence order. The MAX16050/MAX16051 are available in a 28-pin (4mm x 4mm) thin QFN package and are fully specified over the -40°C to +85°C extended operating tempera- ture range.
