The MAX16052/MAX16053 are a family of small, low-power, high-voltage monitoring circuits with sequencing capability. These miniature devices offer very wide flexibility with an adjustable voltage threshold and an external capacitor-adjustable time delay. These devices are ideal for use in power-supply sequencing, reset sequencing, and power switching applications. Multiple devices can be cascaded for complex sequencing applications.A high-impedance input (IN) with a 0.5V threshold allows an external resistive divider to set the monitored threshold. The output (OUT) asserts high when the input voltage rises above the 0.5V threshold and the enable input (EN) is asserted high. When the voltage at IN falls below 0.495V or when the enable input is deasserted (EN = low), the output deasserts (OUT = low). The MAX16052/MAX16053 provide a capacitor programmable delay time from when the voltage at IN rises above 0.5V to when the output is asserted.The MAX16052 offers an active-high open-drain output while the MAX16053 offers an active-high push-pull output. Both devices operate from a 2.25V to 28V supply voltage and feature an active-high enable input. The MAX16052/MAX16053 are available in a tiny 6-pin SOT23 package and are fully specified over the automotive temperature range (-40°C to +125°C).ApplicationsComputers/ServersCritical μP MonitoringIntelligent InstrumentsMedical EquipmentPortable EquipmentSet-Top BoxesTelecom

The MAX16056–MAX16059 are ultra-low-current 125nA (typ) microprocessor (µP) supervisory circuits that monitor a single system supply voltage. These devices assert an active-low reset signal whenever the VCCsupply 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 VCCrises above the reset threshold. Factory-trimmed reset threshold voltages are offered from 1.575V to 4.625V in approximately 100mV increments (see Table 1 in the full data sheet).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 push-pull or open-drain output-type configurations (see theOrdering Informationin the full data sheet). These devices are fully specified over the -40°C to +125°C automotive temperature range. The MAX16056/MAX16058 are available in the 8-pin TDFN package, and the MAX16057/MAX16059 are available in the 6-pin TDFN package.ApplicationsGlucose Monitors/Patient MonitorsMetering/HVACMP3 Players/PagersPDAs/Cell PhonesPortable/Battery-Powered Equipment

The MAX1606 is a step-up DC-DC converter that contains a 0.5A internal power switch and a 0.5A output isolation switch in an 8-pin µMAX® package. The IC operates from a 2.4V to 5.5V supply voltage but can boost battery voltages as low as 0.8V up to 28V.The MAX1606 uses a unique control scheme that provides high efficiency over a wide range of load conditions. An internal 0.5A MOSFET reduces external component count, and a high switching frequency (up to 500kHz) allows for tiny surface-mount components. The current limit can be set to 500mA, 250mA, or 125mA, allowing the user to reduce the output ripple and component size in low-current applications.Additional features include a low quiescent supply current and a true shutdown mode that saves power by disconnecting the output from the input. The MAX1606 is ideal for small LCD panels with low current requirements but can also be used in other applications. A MAX1606 evaluation kit is available to help speed up design time.ApplicationsCell Phones/Cordless PhonesHandy TerminalsLCD Bias GeneratorsOrganizersPalmtop ComputersPDAs and Other Handheld Devices
