General Description

The MAX16165/MAX16166 monitor up to five voltages

and sequence up to four voltages. These devices

provide an adjustable delay as each supply is turned on

as well as monitor each power-supply voltage, including

the input voltage VDD.

The MAX16165/MAX16166 operate from a supply range

of 2.7V to 16V and have an internal regulator output

(ABP), power internal circuits, and supply more than

1mA additional current to any external circuitry.

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 (μC) to operate. If any voltage falls below

its threshold, the reset output asserts and all voltage

supplies are turned off. When the sequencer initiates a

power-off sequencing, the MAX16165/MAX16166 can

reverse sequence the outputs.

Output options available are open-drain (MAX16165)

and push-pull (MAX16166). The MAX16165/MAX16166

can be daisy-chained unlimited amount to time to control

any number of voltages in a system.

The MAX16165/MAX16166 feature a bidirectional active

low FAULT input/output, which asserts low during any

fault condition. FAULT stays low as long as an

undervoltage event is present at UVSET Input and it is a

one-shot output during all other FAULT conditions. An

external signal pulling FAULT low disables all outputs

immediately. The MAX16165/MAX16166 are available

in a 1.63mm x 2.03mm, 20-bump Wafer-Level Package

(WLP) and a 4mm x 4mm, 20L TQFN package. The

device is fully specified over the -40°C to +125°C

operating temperature range.
