Product details
Overview
MAX6717UKLRD3-T from Maxim Integrated is a dual-voltage microprocessor supervisory IC in 5-pin SOT23 package, monitoring VCC1 (1.8V–5.0V) and VCC2 (0.9V–3.3V) with factory-trimmed reset thresholds, 210ms minimum reset timeout, open-drain active-low RST output, and guaranteed reset validity down to VCC1 or VCC2 = 0.8V - used in battery-powered embedded systems for reliable power-up/power-down sequencing.
For engineers reviewing the MAX6717UKLRD3-T datasheet, MAX6717UKLRD3-T pinout, MAX6717UKLRD3-T application, or MAX6717UKLRD3-T equivalent, key selection criteria include dual-supply threshold accuracy (±1.5% typical), ultra-low 14µA supply current at 3.6V, immunity to sub-100ns VCC transients, and compatibility with manual-reset and watchdog-free designs requiring minimal external components.
Technical Context
The MAX6717UKLRD3-T implements two independent voltage comparators with internal hysteresis (0.5% of VTH) and a digital timeout counter triggered on any threshold violation. Its reset logic asserts RST low when either VCC1 falls below its factory-set threshold (e.g., 3.075V) or VCC2 drops below its matched threshold (e.g., 1.665V), holding reset for ≥210ms after both supplies recover.
No watchdog, PFI, PFO, RSTIN, or WDI functions are present - this variant is a dedicated dual-supply monitor with MR input and single open-drain RST output. It operates across –40°C to +125°C and draws only 10µA typical at VCC1 = 3.6V and VCC2 = 2.7V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC1 Threshold | 3.075V (factory-trimmed, falling edge; matches suffix 'L') |
| VCC2 Threshold | 1.665V (factory-trimmed, falling edge; matches suffix 'R') |
| Reset Timeout | 210ms min (suffix 'D3'; ensures µP initialization completes before release) |
| Supply Current | 14µA typ at 3.6V (enables >10-year battery life in always-on IoT nodes) |
| Operating Temp | –40°C to +125°C (supports under-hood automotive and industrial control) |
| Reset Validity | Down to VCC1 or VCC2 = 0.8V (guarantees clean reset assertion during brownout) |
| Output Type | Open-drain active-low RST (requires external pullup; compatible with 1.8V–5V I/O domains) |
Pinout & Package
Package: 5-pin SOT23 (1.6mm × 2.9mm × 1.1mm, JEDEC MO-178AA). Pinout validated per Maxim datasheet Rev 3 (19-0536).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low open-drain reset output; sinks current when asserted; requires external pullup resistor |
| 2 | GND | Analog/digital ground reference; must be low-impedance connection to system ground plane |
| 3 | MR | Active-low manual-reset input; internally pulled up to VCC1 (50kΩ); debounced by 100ns glitch rejection |
| 4 | VCC2 | Secondary supply input (0.9V–3.3V); powers internal comparator for VCC2 monitoring path |
| 5 | VCC1 | Primary supply input (1.8V–5.0V); powers device core and VCC1 monitoring path; defines RST pullup domain if push-pull used (not applicable here) |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent voltage monitoring | Simultaneous VCC1 and VCC2 supervision eliminates need for two discrete supervisors or RC-based solutions |
| Factory-trimmed precision thresholds | VTH1 = 3.075V ±1.5%, VTH2 = 1.665V ±1.5% - removes external resistor calibration and improves BOM consistency |
| Guaranteed reset operation down to 0.8V | Ensures deterministic reset assertion during deep brownout conditions common in Li-ion battery discharge |
| Ultra-low quiescent current | 14µA typical at 3.6V enables use in energy-harvesting and coin-cell-powered applications |
| High noise immunity | Immune to VCC transients <100ns wide - prevents spurious resets in electrically noisy environments |
Applications
| Battery-Powered IoT Sensor Node | Industrial PLC I/O Module |
|---|---|
Use Scenario: A wireless temperature sensor powered by a CR2032 coin cell monitors VCC (3.0V nominal) and MCU core rail (1.8V) during sleep/wake cycles. IC Role / Device Role / Timing Role: Dual-supply supervisor ensures both rails are valid before releasing reset to the ARM Cortex-M0+ MCU and holds reset during brownout recovery. Use Value: 210ms timeout guarantees full RF startup and sensor initialization; 14µA ICC extends battery life beyond 5 years. | Use Scenario: An industrial digital input module uses isolated 24V DC and internal 5V/3.3V rails to power FPGA, isolators, and interface logic. IC Role / Device Role / Timing Role: Monitors 5V primary (VCC1) and 3.3V secondary (VCC2) to assert reset if either rail sags below specification during load switching or ESD events. Use Value: Guaranteed reset validity down to 0.8V prevents latch-up during 24V supply dips; –40°C to +125°C rating supports DIN-rail mounting near motors. |
| Automotive Body Control Module | Medical Portable Diagnostic Device |
Use Scenario: A BCM monitors 5V infotainment rail and 3.3V microcontroller rail in a 12V vehicle electrical system subject to cold-crank and load-dump transients. IC Role / Device Role / Timing Role: Provides fail-safe reset coordination between power management IC and MCU during battery voltage collapse. Use Value: Immunity to sub-100ns VCC glitches avoids false resets during alternator ripple; AEC-Q100 stress qualification supported via Maxim's automotive-grade process. | Use Scenario: A handheld ultrasound probe uses dual Li-ion cells (6.4V–8.4V) stepped down to 3.3V and 1.8V for analog front-end and digital processing. IC Role / Device Role / Timing Role: Supervises both regulated rails to prevent corrupted image acquisition during battery voltage sag or thermal shutdown. Use Value: Factory-trimmed thresholds eliminate calibration drift over 5-year product lifetime; open-drain RST interfaces safely with mixed-voltage FPGA I/O banks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-voltage supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3808G33DBVR | Single-supply monitor (3.3V only); no VCC2 input; fixed 200ms timeout; push-pull RST | Cannot supervise dual rails simultaneously; requires separate VCC2 monitor or resistor-divider scaling | Select only if system has single regulated rail and needs push-pull output without external pullup |
| ADM6710LAKSZ-REEL7 | Dual-supply monitor with 3.08V/1.63V thresholds; 200ms timeout; open-drain RST; 18µA ICC | Thresholds differ by ±0.015V; 10ms shorter timeout; higher supply current reduces battery life margin | Acceptable drop-in for space-constrained designs where 10ms timeout variance is acceptable and 4µA higher ICC is tolerable |
Compared with TPS3808G33DBVR and ADM6710LAKSZ-REEL7, MAX6717UKLRD3-T uniquely delivers matched dual-threshold precision (3.075V/1.665V), 210ms timeout headroom, and lowest ICC (14µA) - making it optimal for battery-critical dual-rail systems where timing margin and energy efficiency are non-negotiable.

FAQ
What is the exact reset threshold voltage for VCC1 and VCC2 on the MAX6717UKLRD3-T?
The MAX6717UKLRD3-T has factory-trimmed reset thresholds: VCC1 = 3.075V (±1.5%) and VCC2 = 1.665V (±1.5%), as defined by the 'L' and 'R' suffixes in the part number per Maxim's Reset Voltage Threshold Suffix Guide. These values are measured at TA = +25°C and exhibit ±20ppm/°C tempco.
Does the MAX6717UKLRD3-T include a watchdog timer or power-fail input?
No, the MAX6717UKLRD3-T does not include watchdog (WDI), power-fail (PFI/PFO), or adjustable RSTIN functionality. It is a dedicated dual-supply supervisor with only VCC1, VCC2, MR, RST, and GND pins - confirmed by its 5-pin SOT23 package and absence of WDI/PFI/RSTIN pins in the official pinout.
What is the minimum supply voltage required for the MAX6717UKLRD3-T to assert a valid reset signal?
The MAX6717UKLRD3-T guarantees correct reset output logic state when either VCC1 or VCC2 remains greater than 0.8V. Below 0.8V, reset behavior is not specified - so system design must ensure at least one supply stays ≥0.8V during brownout to maintain deterministic reset assertion.
Can the MAX6717UKLRD3-T be used with a 1.2V VCC2 supply?
Yes, the MAX6717UKLRD3-T supports VCC2 inputs from 0.9V to 3.3V, so a 1.2V rail is within specification. However, its factory-set VCC2 threshold is 1.665V - meaning it will assert reset if the 1.2V rail drops below that level. For accurate monitoring of a 1.2V rail, select a variant with lower VCC2 threshold (e.g., suffix 'D' = 1.050V).
Is an external pullup resistor required for the RST pin on the MAX6717UKLRD3-T?
Yes, the MAX6717UKLRD3-T features an open-drain active-low RST output, which requires an external pullup resistor to the desired logic rail (e.g., 3.3V or 5V). Typical values range from 4.7kΩ to 100kΩ; lower values improve rise time but increase static current, while higher values reduce current but risk noise susceptibility.
