MAX16088XS44F+T 개요
A voltage supervisor is a type of power management integrated circuit (PMIC) that belongs to the supervisors-and-reset IC category. Within the broader system hierarchy, supervisors fall under power management ICs - semiconductors that regulate, monitor, and protect voltage rails. Supervisors specifically ensure deterministic processor behavior by forcing a known reset state whenever the supply rail becomes unreliable. This is critical for embedded systems where uncontrolled code execution during brownouts can corrupt flash memory, registers, or cause mechanical/communications faults.
Key features of the MAX16088XS44F+T include a 4.375V ±1.5% threshold accuracy, an open-drain active-low RESET output, an ultra-low 0.7 µA (typical) supply current that makes it ideal for battery-powered applications, and a 200 ms minimum reset timeout. The SC70-4 package occupies only ~2.0 mm × 2.1 mm of PCB area - one of the smallest footprints in the supervisor category - and operates over a -40°C to +85°C extended industrial temperature range. The wide VCC supply range of 1.0V to 5.5V allows monitoring of common 3.3V, 3.0V, 2.5V, 1.8V, and 1.2V rails from the same part.
Architecturally, the MAX16088XS44F+T uses a precision bandgap reference and comparator core to compare VCC against the trimmed threshold, combined with an internal timing generator for the reset pulse-width. The design avoids the need for an external timing capacitor - unlike many legacy supervisors such as the MAX809 - by integrating a fixed-factory timeout.
Typical applications include battery-powered IoT sensor nodes, wearable health monitors, portable consumer electronics, MCU/SoC rail monitoring, energy harvesting nodes, and industrial sensor endpoints. The low quiescent current (0.7 µA typ.) makes it especially suitable where sleep-mode drain dominates system budgets.
Designers should choose a pull-up resistor on RESET (open-drain) sized appropriately for the load capacitance to meet reset rise-time requirements, and verify that VCC ramp time is faster than the device's minimum VCC slew specification. For more margin, consider the MAX16087 variant family with adjustable thresholds.

일반적인 애플리케이션
MAX16088XS44F+T 적합 용도: 6 애플리케이션s: Battery-Powered IoT Sensor Node Monitoring, MCU / SoC Brownout Protection, Wearable Health Monitor, Portable Consumer Electronics, Industrial Sensor Endpoint, Energy Harvesting Wireless Node.
Battery-Powered IoT Sensor Node Monitoring
The MAX16088XS44F+T monitors a 3.3V or 5V rail on battery-powered IoT sensor endpoints, asserting RESET whenever the rail sags below 4.375V during transmit-burst brownouts. Its 0.7 µA quiescent current adds negligible drain to multi-year coin-cell budgets (under 6 mAh/year contribution) versus legacy supervisors that draw 5-10 µA. The SC70-4 footprint fits beside BLE/Zigbee SoC power pins without crowding RF sections. Place a 47 kΩ pull-up on RESET to the SoC's GPIO VCC domain for level shifting, and verify VCC ramp < 100 µs to meet the device's minimum slew-rate requirement.
추천
MCU / SoC Brownout Protection
The MAX16088XS44F+T provides hardware-reset protection for microcontroller and SoC supply rails, asserting RESET for 200 ms minimum whenever VCC dips below the 4.375V threshold. This prevents the MCU from executing corrupted firmware during power-down or momentary brownout events - protection internal brownout detectors (BOD) cannot guarantee because they are disabled during reset and may have loose ±5-10% thresholds. Tie RESET to the MCU's NRST pin via 10 kΩ pull-up to VCC; the SC70-4 footprint sits within 2 mm of the MCU's supply pin to minimize parasitic inductance.
추천
Wearable Health Monitor
The MAX16088XS44F+T is suited to wearable health patches and continuous monitors where PCB area is constrained and battery life dominates. Its 2.0 mm × 2.1 mm SC70-4 package is one of the smallest in any supervisor family, and 0.7 µA quiescent current contributes <0.5% of typical 200 µA wearable quiescent load. For 3.0V coin-cell rails, choose the MAX16088XS29F+T (2.925V) variant instead. Designers should use a 100 kΩ pull-up to minimize reset-line current and verify ESD clamping via series resistor on RESET traces near body-contact electrodes.
추천
Portable Consumer Electronics
The MAX16088XS44F+T supervises lithium-ion battery-powered consumer devices - portable speakers, e-readers, and handheld instruments - where the 5V boost-converter output must remain above 4.375V during transmit bursts or backlight turn-on. The 200 ms reset timeout covers boost-converter soft-start intervals (typically 50-150 ms) and prevents false reset triggers. SC70-4 placement near the boost IC's output reduces ground-bounce coupling; bypass VCC with a 100 nF X7R ceramic placed within 3 mm of Pin 2.
추천
Industrial Sensor Endpoint
In factory-floor wireless sensor endpoints drawing power from energy harvesting or 24V-to-5V isolated rails, the MAX16088XS44F+T provides deterministic supervisor function across the -40°C to +85°C industrial range. The ±1.5% threshold accuracy holds across temperature - critical for industrial reliability programs - whereas internal MCU BOD can drift 5-10% over temperature. For fail-safe designs, route RESET through a redundant OR-diode with the MCU's internal POR for dual-path supervision.
추천
Energy Harvesting Wireless Node
Energy-harvesting wireless sensor nodes (solar, vibration, thermal) using the MAX16088XS44F+T benefit from 0.7 µA Iq, which is <2% of typical 50 µA harvester output. The supervisor's 4.375V threshold suits 5V rectified harvester buses; for lower-voltage harvesters choose the MAX16088XS29F+T or MAX16088XS18F+T. The SC70-4 footprint enables PCB stacking in matchbox-sized nodes. Use a 1 MΩ pull-up to minimize reset-line drain during the harvester's quiescent periods.

설계 노트
Place the MAX16088XS44F+T within 3 mm of the MCU's VCC pin to minimize parasitic inductance on the monitored rail. Add a 100 nF X7R bypass capacitor directly on Pin 2 (VCC) with the ground return within 5 mm of Pin 1 (GND). Keep digital switching traces (clocks, data) at least 5 mm from the RESET pin to prevent capacitive coupling that could false-trigger reset. For high-noise industrial environments, add a 10 Ω series ferrite bead on VCC.
The active-low open-drain RESET output requires an external pull-up resistor. Choose 10 kΩ to 100 kΩ depending on the RESET trace capacitance: 10 kΩ for < 50 pF, 47 kΩ for 50-200 pF, 100 kΩ for > 200 pF. Lower pull-up values give faster rise-times but draw more current. For multi-supply systems, tie the pull-up to the SoC's I/O supply rather than the monitored rail to ensure correct logic-level translation when the monitored rail sags below threshold.
Do not use the MAX16088XS44F+T on rails below 1.0V - it requires VCC ≥ 1.0V to operate. Verify that VCC ramp time on power-up is faster than the device's minimum VCC slew specification (typically 100 µs); very slow ramps can cause the part to enter undefined states. For voltage rails other than 5V nominal, choose the variant with the appropriate threshold (XS29 = 3V, XS18 = 1.8V) - do not assume this 4.375V-threshold part works on a 3.3V rail.
The 0.7 µA typical quiescent current is the dominant power contribution in sleep-mode designs. For energy budgets, calculate annual drain as: Iq × 8760 hours × 3.6 = ~22 mAh/year per µA, so 0.7 µA → ~15 mAh/year. For applications demanding <5 mAh/year sleep drain, consider zero-Iq parts like the TPS3836 or use a load switch with the supervisor gating the main rail.
