MAX16058
Description
The MAX16056- MAX16059 are ultra-low-current 125n A (typ) microprocessor (µP) supervisory circuits that monitor a single system supply voltage. These devices assert an active-low reset signal whenever the V CC supply voltage drops below the factory-trimmed reset threshold, manual reset is pulled low, or the watchdog timer runs out (MAX16056/MAX16058). The reset output remains asserted for an adjustable reset timeout period after V CC rises above the reset threshold. Factorytrimmed reset threshold voltages are offered from 1.575V to 4.625V in approximately 100m V increments (see Table 1). These devices feature adjustable reset and watchdog timeout using external capacitors. The MAX16056/ MAX16058 contain a watchdog timer with a watchdog select input (WDS) that multiplies the watchdog timeout period by 128. The MAX16057/MAX16059 do not have the watchdog feature
. The MAX16056- MAX16059 are available in either pushpull or open-drain output-type configurations (see the Ordering...
