Product details
Overview
MAX6383XR41D6-T from Maxim Integrated is an open-drain active-low microprocessor supervisory circuit designed for power-supply voltage monitoring in low-power embedded systems. It features a factory-set reset threshold of +4.10V (±2.5% over -40°C to +125°C), 560ms minimum reset timeout, and consumes only 3μA at +1.8V. It operates across 1.0V to 5.5V supply range and guarantees valid reset output down to VCC = 1V - used in portable equipment, dual-voltage controllers, and critical μP power sequencing.
For engineers reviewing the MAX6383XR41D6-T datasheet, MAX6383XR41D6-T pinout, MAX6383XR41D6-T application, or MAX6383XR41D6-T equivalent, key selection criteria include its open-drain active-low reset architecture, precise +4.10V threshold with ±2.5% tempco, 560ms timeout, SC70-3 package compatibility, and guaranteed operation down to VCC = 1V for brownout resilience.
Technical Context
The MAX6383XR41D6-T implements a precision bandgap-based reset comparator with internal reference and a monolithic timer for deterministic reset assertion timing. Its open-drain RESET output requires an external pullup resistor and supports mixed-voltage system interfacing. The device lacks MR or RESET IN inputs - confirming it is a single-supply, fixed-threshold, no-manual-reset variant within the MAX6383 family.
It uses BiCMOS process technology and is rated for -40°C to +125°C operation. Absolute maximum VCC is +6.0V, and RESET output can sink up to 3.2mA at VCC ≥ 4.5V while maintaining VOL ≤ 0.4V - enabling direct interface with 3.3V/5V logic families without level-shifting.
Key Specifications

| Factory-trimmed reset threshold | +4.10V with ±2.5% accuracy over full industrial temperature range - eliminates need for external calibration or trimming resistors |
| Ultra-low quiescent current | 3μA at +1.8V - reduces standby power in battery-backed systems and extends shelf life of portable instrumentation |
| Guaranteed reset validity down to VCC = 1V | Ensures deterministic reset state during severe brownout - prevents μP lockup or undefined execution before power collapse completes |
| Negative-going VCC transient immunity | Rejects glitches ≤100ns at 100mV overdrive - improves robustness against switching noise in DC-DC converter environments |
| SC70-3 footprint compatibility | Direct pin-to-pin replacement for MAX809/MAX810 series - enables legacy design refresh without PCB layout changes |
Applications
| Portable Power Management | Dual-Voltage System Monitoring |
|---|---|
Use Scenario: Battery-powered handheld meter with 3.3V I/O and 1.8V core rails, requiring independent power-fail detection on main supply. IC Role / Device Role / Timing Role: Primary VCC supervisor asserting open-drain reset to both μP and FPGA upon 4.1V rail collapse. Use Value: 560ms timeout ensures complete shutdown sequence execution; 3μA ICC preserves battery capacity during extended idle periods. | Use Scenario: Industrial PLC module with separate 5V analog front-end and 3.3V digital controller, needing coordinated reset initiation. IC Role / Device Role / Timing Role: Single-point reset generator triggered by 4.1V main supply failure, driving shared reset bus via open-drain topology. Use Value: Open-drain output enables safe wired-OR with other supervisors; ±2.5% threshold tolerance prevents false resets due to rail ripple. |
| Embedded Controller Sequencing | Low-Power Sensor Node Supervision |
Use Scenario: Automotive body control module using ARM Cortex-M0+ MCU, where 4.1V system rail powers multiple subsystems. IC Role / Device Role / Timing Role: Dedicated reset monitor ensuring μP enters known state only after stable 4.1V rail is confirmed for ≥560ms. Use Value: Valid reset assertion down to VCC = 1V prevents spurious wakeups during cold-cranking transients. | Use Scenario: Wireless environmental sensor node powered by coin-cell battery, operating intermittently with deep sleep cycles. IC Role / Device Role / Timing Role: Always-on supervisor detecting 4.1V boost converter output failure before μC wakes for measurement. Use Value: 3μA supply current contributes <0.1% to total sleep-mode load - extending operational lifetime beyond 5 years. |

FAQ
What is the exact reset threshold voltage of the MAX6383XR41D6-T?
The MAX6383XR41D6-T has a factory-set nominal reset threshold of +4.10V, with guaranteed accuracy of ±2.5% over the full operating temperature range of -40°C to +125°C. This value is confirmed in the Reset Thresholds table of the official datasheet, where suffix "41" corresponds to VTH(nom) = 4.10V. The MAX6383XR41D6-T does not support adjustable thresholds or external resistor networks - its detection point is fixed and laser-trimmed during manufacturing.
Does the MAX6383XR41D6-T include a manual reset input (MR)?
No, the MAX6383XR41D6-T does not feature a manual reset input. Per the Selector Guide and Pin Configurations, only MAX6384/MAX6385/MAX6386/MAX6390 variants include MR functionality. The MAX6383XR41D6-T is a dedicated single-supply supervisor with RESET, VCC, and GND terminals only - confirmed by its 3-pin SC70 pinout and absence of MR in all electrical characteristics tables.
What is the minimum reset timeout period specified for the MAX6383XR41D6-T?
MAX6383XR41D6-T has a minimum reset timeout period of 560ms, as indicated by the "D6" suffix in its part number. This is verified in the Reset Timeout Delay table, where D6 maps to 560ms (min). The actual timeout may extend up to 1120ms depending on process and temperature variation, but the guaranteed minimum remains 560ms - sufficient for most μP initialization sequences including flash memory wake-up and PLL lock times.
Can the MAX6383XR41D6-T operate reliably below 1.8V supply voltage?
Yes, the MAX6383XR41D6-T is fully specified to operate from VCC = 1.0V to 5.5V. Its reset output remains valid (correct logic state) down to VCC = 1V, and supply current drops to ~3μA at 1.8V and remains functional at lower voltages. However, output sink capability degrades below 2.5V - at VCC = 1.0V, it guarantees only 80μA sink current with VOL ≤ 0.3V, which is adequate for high-impedance CMOS inputs but insufficient for driving LEDs or heavy loads.
Is the MAX6383XR41D6-T pin-compatible with the MAX809 series?
Yes, the MAX6383XR41D6-T is pin-compatible with the MAX809/MAX810 family in the 3-pin SC70 package. Both share identical pin assignments: Pin 1 = RESET (open-drain), Pin 2 = VCC, Pin 3 = GND. This compatibility is explicitly stated in the Features section and validated by matching outline numbers (21-0075) and land patterns (90-0208), enabling direct substitution in existing designs without layout modification.
