The MAX16161/MAX16162 are ultra-low current, singlechannelsupervisory ICs. The devices monitor the powersupply voltage and assert a reset when the input voltagefalls below the reset threshold. After the monitoring voltagerises above the factory-set threshold voltage (VTH),the reset output remains asserted for the reset timeoutperiod and then deasserts, allowing the target microcontrolleror microprocessor to leave the reset state and beginoperating.Unlike conventional supervisors, which are unable to controlthe reset output state when VCC is very low, theMAX16161/MAX16162 reset output is guaranteed to remainasserted until after a valid VCC is achieved. Thisis especially important to avoid low-voltage cores leavingthe reset state during power-up or power-down. This alsoimproves performance when using the MAX16161/MAX16162 as simple power supply sequencers, becausethe devices will never cause a transient enable of a downstreampower supply due to output glitches.The MAX16161 features a manual reset (MR) input thatasserts a reset when it receives an appropriate input signal,which may be either active-low or active-high, dependingon the option. The MAX16162 has no MR input.Instead, it has separate VCC and VIN pins, allowingthreshold voltages as low as 0.6V. The reset output is active-low open-drain, and the MAX16161/MAX16162 offermultiple available reset timeout period options.The MAX16161/MAX16162 are specified over the -40°Cto +125°C temperature range and are available in tiny,1.06mm x 0.73mm, 4-bump WLP and 4-pin SOT23 packages. The MAX16162 is also available in a 5-pin SOT23 package.Applicationse-Readers/TabletsLow-Voltage Microcontrollers and MicroprocessorsPortable/Battery-Powered EquipmentSmart PhonesWearable/Portable Accessories

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.ApplicationsFPGA/ASIC Power Supply SequencingIndustrial Sensors and Motor ControlsLatch-Up Prevention and Inrush Current Protection in Multi-Supply SystemsNetworking EquipmentServers and Security CamerasTest Equipment

The MAX16602 IC provides a high-density, flexible and scalable solution to power AI cores or Intel® VR13.HC server CPUs. This Maxim controller IC employs coupled inductors and smart power-stage ICs to implement high-efficiency core regulators with enhanced transient response and low quiescent current. An additional single-phase output generates the VSA rail in the system using a single-phase smart power stage. The complete circuit is a highly efficient (8+1) multiphase synchronous buck converter with extensive status and parameter-measurement features. The controller also supports PWM paralleling to control up to 16 phases. A single, scalable PCB design with appropriate smart power stage IC selection can be used to produce regulators with a wide range of current ratings.The IC’s architecture simplifies design, reduces component count, enables advanced power management and telemetry, and increases energy savings over the full load range. Autonomous phase-shedding is implemented to maintain high efficiency across the entire load range.Regulator parameters for protection and shutdown can be set and monitored through the serial interface using the PMBus™ protocol. Power-stage faults, input and output voltage, input and output current, input power, and the temperature of each smart power-stage IC are readable over the serial interface. The critical fault retention feature prevents exothermic events after a power-device fault. The smart power-stage ICs communicate with the controller IC through analog and digital signals that are also readable through the registers in the controller IC. Preset and user configurations are programmed in nonvolatile memory (NVM). MTP-programmable NVM circuits allow for seven field modifications.An integrated 3.3V to 1.8V regulator supports both MAX16602 and power-stage ICs with 1.8V bias supplies. SNS_PS_BIAS monitoring also allows for flexible bias and sequencing.The MAX16602 is available in a 56-pin, 7mm x 7mm QFN package.ApplicationsHigh-Current Multiphase Voltage Regulators- AI Cores and XPUs- VR13.HC CPUs and Memory- Graphics Processors- Networking ASICsServers and WorkstationsEnterprise StorageCommunications and Networking Equipment Supply
