Product details
Overview
The MAX16059ATT30+T from Analog Devices is a 6-pin TDFN ultra-low-power microprocessor supervisory circuit with factory-trimmed 3.000V reset threshold, capacitor-adjustable reset timeout (10.5–17.0ms), push-pull RESET output, and no watchdog timer. It monitors single-supply VCC (1.1–5.5V) and asserts active-low reset during brownout, manual reset, or power-up/down - used in glucose monitors, portable medical devices, and battery-powered metering systems.
For engineers reviewing the MAX16059ATT30+T datasheet, MAX16059ATT30+T pinout, MAX16059ATT30+T application, or MAX16059ATT30+T equivalent, key selection criteria include its 125nA typical supply current at 3.3V/25°C, guaranteed RESET validity down to VCC = 1.1V, -40°C to +125°C automotive temperature range, and compatibility with low-leakage ceramic SRT capacitors (39pF–4.7µF).
Technical Context
The MAX16059ATT30+T implements a precision voltage-monitoring architecture with internal hysteresis (0.5%) and a ramp-based timing circuit for capacitor-adjusted reset timeout. Its reset assertion is triggered by VCC falling below 3.000V ±2.5% over temperature, with 80µs VCC-to-reset delay and guaranteed deassertion only after VCC exceeds VTH + VHYST.
Unlike the MAX16056/MAX16058 variants, this device omits WDI, WDS, and SWT pins - eliminating watchdog functionality while retaining MR input, SRT-based timeout adjustment, and push-pull RESET drive capable of sinking 50µA at 0.3V or 3.2mA at 0.4V (VCC ≥ 4.5V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 125nA typ at 3.3V/25°C; enables multi-year battery life in always-on medical sensors |
| Reset Threshold | 3.000V ±1.5% at 25°C, ±2.5% over -40°C to +125°C; matches 3.0V system rails |
| Reset Timeout | 10.5–17.0ms with 2700pF SRT capacitor; ensures reliable µP initialization after power recovery |

Pinout & Package
Package: 6-pin 3mm × 3mm TDFN-EP with exposed pad (EP) connected to GND per datasheet recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 RESET | Active-low push-pull reset output | Drives µP reset pin directly; sinks 50µA @ 0.3V (VCC ≥ 1.0V) or 3.2mA @ 0.4V (VCC ≥ 4.5V) |
| 2 GND | Ground reference | Return path for all internal circuits; must be low-impedance connection to system ground |
| 3 N.C. | No internal connection | Unbonded pin; leave floating or tie to GND for mechanical stability (no electrical effect) |
| 4 MR | Manual reset input | CMOS-compatible active-low input; 1µs minimum pulse width; no internal pullup |
| 5 SRT | Reset timeout capacitor input | Connects to GND via low-leakage capacitor (39pF–4.7µF); sets tRP = 5.15×10⁶ × CSRT |
| 6 VCC | Power supply input | Monitored supply rail; bypass with 0.1µF ceramic capacitor to GND for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ICC | 125nA typ at 3.3V enables >10-year operation on CR2032 in intermittent-sensing applications |

| Capacitor-adjustable tRP | SRT pin allows precise, board-level tuning of reset hold time without firmware changes |
| Guaranteed RESET validity | RESET remains functional down to VCC = 1.1V - critical for graceful shutdown in brownout |
| Transient immunity | Immune to ≤40µs, 100mV VCC transients - avoids spurious resets in noisy automotive/metering environments |
Applications
| Glucose Monitoring Systems | Patient Vital Sign Monitors |
|---|---|
Use Scenario: Portable handheld glucose meters powered by single CR2032 coin cell with intermittent sensor activation. IC Role / Device Role / Timing Role: Supervises 3.0V regulated rail; asserts RESET during battery voltage sag below 3.0V to prevent corrupted ADC readings or flash writes. Use Value: 125nA ICC extends battery life beyond 2 years; push-pull RESET eliminates pullup resistor, saving PCB area and BOM cost. | Use Scenario: Wearable ECG/SpO₂ patches requiring continuous low-power operation and fail-safe boot sequencing. IC Role / Device Role / Timing Role: Monitors main 3.3V LDO output; holds µP in reset until rail stabilizes post-power-on, then releases after 14.18ms (2700pF SRT). Use Value: Guaranteed RESET validity to 1.1V prevents undefined logic states during deep brownout; -40°C to +125°C rating supports clinical and field use. |
| Smart Utility Meters | HVAC Sensor Nodes |
Use Scenario: Battery-backed AMI meters operating in unconditioned outdoor enclosures with wide temperature swings. IC Role / Device Role / Timing Role: Resets metrology SoC when 3.0V backup rail drops due to capacitor aging or cold-temperature derating. Use Value: ±2.5% VTH tolerance over full temp range ensures consistent trip point; 6-pin TDFN footprint minimizes layout area in space-constrained modules. | Use Scenario: Wireless HVAC temperature/humidity nodes powered by two AA alkaline cells with seasonal voltage decay. IC Role / Device Role / Timing Role: Detects end-of-life battery drop below 3.0V and forces controlled shutdown before data corruption occurs. Use Value: MR input enables user-initiated recalibration reset; capacitor-adjustable tRP accommodates varying µP startup sequences across firmware revisions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar supervisory circuit applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16057ATT30+T | Identical pinout, package, and reset specs; differs only in top mark (ATU vs ATT) - same die, alternate ordering code | No functional difference; both are 6-pin TDFN, push-pull, no watchdog, 3.000V threshold | Select MAX16057ATT30+T only if required by legacy BOM or distributor stock alignment |
| TPS3808G30DBVR | 3.0V threshold, 1.5µA ICC (vs 125nA), SOT-23-6 package, fixed 200ms reset timeout (non-adjustable) | Suitable for cost-sensitive industrial controls where ultra-low power is secondary to procurement simplicity | Choose TPS3808G30DBVR only when adjustable timeout is unnecessary and higher ICC is acceptable |
Compared with MAX16057ATT30+T (identical function) and TPS3808G30DBVR (higher ICC, fixed timeout), the MAX16059ATT30+T uniquely delivers nano-power operation with board-tunable reset timing in a compact 3mm × 3mm footprint - essential for long-life portable medical and metering designs.

FAQ
What is the factory-trimmed reset threshold voltage for MAX16059ATT30+T?
The MAX16059ATT30+T has a factory-trimmed reset threshold of 3.000V, with ±1.5% accuracy at +25°C and ±2.5% over the full -40°C to +125°C operating range. This value is confirmed in Table 1 of the datasheet under suffix "30", and applies specifically to the MAX16059ATT30+T variant - not extrapolated from adjacent thresholds.
Does MAX16059ATT30+T include a watchdog timer?
No, the MAX16059ATT30+T does not include a watchdog timer. As confirmed in the Typical Operating Circuit table and Pin Description section, MAX16059 variants omit WDI, WDS, and SWT pins entirely. Watchdog functionality is exclusive to MAX16056/MAX16058 (8-pin TDFN) versions.
What capacitor value sets the nominal reset timeout for MAX16059ATT30+T?
A 2700pF capacitor on the SRT pin sets the nominal reset timeout of 14.18ms for MAX16059ATT30+T, as specified in the Electrical Characteristics table under tRP (CSRT = 2700pF). This value is validated across temperature and matches Table 2's entry for 2700pF.
Is MAX16059ATT30+T compatible with 1.8V microcontrollers?
Yes, MAX16059ATT30+T is fully compatible with 1.8V µPs: its VCC operating range (1.1–5.5V) includes 1.8V, and its push-pull RESET output guarantees VOH ≥ 0.8×VCC and VOL ≤ 0.4V when sinking 3.2mA - meeting standard 1.8V CMOS input thresholds.
What is the thermal resistance of the MAX16059ATT30+T package?
The MAX16059ATT30+T uses a 6-pin TDFN-EP package with θJA = 42°C/W and θJC = 9°C/W, measured per JEDEC JESD51-7 on a four-layer board. These values are explicitly listed in the Package Thermal Characteristics section and apply to the 6-pin variant (not the 8-pin MAX16056/MAX16058).
