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 active-low OFF. A rising edge on the ON input initiates power-on sequencing of the channels whereas a falling edge on active-low 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. Active-low FAULT stays low as long as an undervoltage event is present at UVSET Input and it is a one-shot output during all other active-low FAULT conditions. An external signal pulling active-low 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.
