Description
The thresholds of the MAX6892/MAX6893/MAX6894 are selected through five logic inputs (TH0–TH4). The logic on these five inputs selects the supply voltage tolerance (5% or 10%) and one of 32 factory-set thresholds settings. Watchdog and reset timeout periods can use factory default settings or are independently adjustable by connecting external capacitors.
When any of the monitored voltages falls below its threshold, the respective output asserts and remains asserted for 6.25ms (typ) after the monitored voltage exceeds the threshold. The outputs can be connected to the shutdown or enable inputs of DC-DC regulators to provide turn-on power sequencing to ensure proper system initialization.
The MAX6892 is available in a 5mm x 5mm x 0.8mm, 32-pin, Thin QFN package, while the MAX6893/MAX6894 are available in a 5mm x 5mm x 0.8mm, 28-pin, Thin QFN package. The MAX6892/MAX6893/MAX6894 are specified to operate over the extended temperature range (-40°C to +85°C).
