Product details
Overview
MAX6383LT17D6+ from Maxim Integrated is a low-power microprocessor supervisory circuit with open-drain active-low reset output, factory-set 1.67V reset threshold (±2.5% over -40°C to +125°C), and 560ms minimum reset timeout period. It monitors VCC from +1.0V to +5.5V while consuming only 3µA at +1.8V, and guarantees valid reset state down to VCC = 1V. Used in portable battery-powered equipment for reliable power-up/brownout detection.
For engineers reviewing the MAX6383LT17D6+ datasheet, MAX6383LT17D6+ pinout, MAX6383LT17D6+ application, or MAX6383LT17D6+ equivalent, key selection criteria include its open-drain reset architecture, 1.67V threshold tolerance, 560ms timeout, SC70/µDFN package compatibility, and immunity to negative-going VCC transients up to 35µs at 100mV overdrive.
Technical Context
The MAX6383LT17D6+ implements a precision voltage comparator with internal 1.67V reference and ±2.5% threshold accuracy across -40°C to +125°C, paired with a temperature-stable monostable timer generating a guaranteed-minimum 560ms reset assertion after VCC recovery. Its open-drain RESET output requires an external pullup and supports mixed-voltage system interfacing.
No manual reset (MR) or auxiliary RESET IN inputs are present - this variant is a dedicated single-supply monitor. The device operates from 1.0V to 5.5V supply and maintains correct logic state on RESET down to VCC = 1V, enabling robust operation during deep brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 1.67V nominal, ±2.5% over -40°C to +125°C - ensures accurate brownout detection across automotive/industrial temperature range |
| Reset Timeout | 560ms minimum - holds µP in reset long enough for power rails and clocks to stabilize post-brownout |
| Supply Current | 3µA at +1.8V - enables multi-year battery life in always-on portable instrumentation |
| Operating Voltage | +1.0V to +5.5V - supports operation down to near-dead battery levels while maintaining reset validity |
| RESET Output Type | Open-drain active-low - allows wired-OR configuration and level-shifting with external pullup resistor |
| VCC Transient Immunity | 35µs max duration at 100mV overdrive - suppresses false resets from short supply glitches |
| Output Sink Capability | 0.3V max at 1.2mA (VCC ≥ 2.5V) - ensures strong low-state drive into typical µP reset inputs |
Pinout & Package
MAX6383LT17D6+ is available in a 3-pin SC70 package (pin code X3+2) and a 6-pin µDFN package (pin code L611+1). Both packages are RoHS-compliant (+ suffix) and rated for -40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SC70) / 1 (µDFN) | GND | Ground reference for all internal circuitry and reset comparator; must be low-impedance connection |
| 2 (SC70) / 4 (µDFN) | VCC | Primary supply input and monitored voltage rail; powers device and feeds reset comparator |
| 3 (SC70) / 2 (µDFN) | RESET | Open-drain active-low reset output; requires external pullup resistor to host system voltage |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed reset threshold | 1.67V with ±2.5% accuracy over full temperature range - eliminates need for external resistor divider calibration |
| Low quiescent current | 3µA at 1.8V - extends battery runtime in energy-constrained IoT sensors and wearables |
| Guaranteed reset validity | Operates correctly down to VCC = 1.0V - prevents spurious release during deep undervoltage events |
| Negative transient rejection | Immune to VCC glitches ≤35µs at 100mV overdrive - avoids false resets in electrically noisy environments |
| Open-drain output architecture | Supports mixed-voltage systems and bus-wired reset distribution without level translators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD3+T | 1.63V reset threshold (±2%), 240ms timeout, push-pull active-low output, 3-pin SOT23 | Lacks open-drain flexibility; incompatible with wired-OR or level-shifted reset buses | Select when board layout uses SOT23 footprint and system requires push-pull drive without external pullup |
| TPS3808G16DBVR | 1.6V threshold (±0.5%), 200ms timeout, open-drain active-low, 5-pin SOT23 | Higher accuracy but shorter timeout; requires 5-pin layout and different thermal profile | Select when tighter threshold tolerance is critical and 200ms timeout suffices for system stabilization |
Compared with MAX809TRD3+T and TPS3808G16DBVR, the MAX6383LT17D6+ offers longer 560ms reset hold time for complex power-rail sequencing, guaranteed operation down to 1.0V VCC, and SC70/µDFN footprints optimized for space-constrained portable designs.

FAQ
What is the exact reset threshold voltage of MAX6383LT17D6+ and how tightly is it specified?
The MAX6383LT17D6+ has a factory-set nominal reset threshold of 1.67V, with guaranteed accuracy of ±2.5% over the full operating temperature range of -40°C to +125°C. This specification is confirmed in the Electrical Characteristics table under "VCC Reset Threshold" and applies directly to the LT17 suffix variant. The MAX6383LT17D6+ achieves this tolerance via laser trimming during production, eliminating need for external calibration.
Does MAX6383LT17D6+ include a manual reset input (MR) or auxiliary RESET IN pin?
No, the MAX6383LT17D6+ does not include a manual reset (MR) input or auxiliary RESET IN pin. Per the Selector Guide and Pin Description tables, MR is present only on MAX6384/MAX6385/MAX6386/MAX6390, and RESET IN appears only on MAX6387/MAX6388/MAX6389. The MAX6383LT17D6+ is a dedicated single-supply monitor with RESET, VCC, and GND only - verified by its 3-pin SC70 and 6-pin µDFN pinouts.
What is the minimum reset timeout period for MAX6383LT17D6+, and is it guaranteed over temperature?
The MAX6383LT17D6+ provides a minimum reset timeout period of 560ms, corresponding to the D6 suffix per the Reset Timeout Delay table. This value is guaranteed over the full -40°C to +125°C temperature range, as confirmed in the Electrical Characteristics section where tRP (D6) is listed as 560ms (min) with no temperature derating. The normalized timeout vs. temperature plot (toc03) shows variation within ±1.5% across temperature.
Can MAX6383LT17D6+ operate reliably when VCC drops below 1.8V?
Yes, the MAX6383LT17D6+ is fully specified to operate down to VCC = 1.0V, with guaranteed valid RESET output state throughout that range. At VCC = 1.0V, the open-drain RESET output maintains proper logic levels (VOL ≤ 0.3V at 80µA sink), and the reset comparator remains functional. This capability is explicitly stated in Absolute Maximum Ratings and Electrical Characteristics, making the MAX6383LT17D6+ suitable for deep brownout scenarios where other supervisors fail.
Is MAX6383LT17D6+ pin-compatible with legacy Maxim reset ICs like MAX809?
The MAX6383LT17D6+ is not pin-compatible with MAX809 in the same package - MAX809 uses 3-pin SOT23, while MAX6383LT17D6+ uses 3-pin SC70 or 6-pin µDFN. However, the datasheet states pin compatibility *across functionally similar Maxim families* (e.g., MAX6326/MAX6346) in matching packages. For SC70, MAX6383LT17D6+ shares pinout with other MAX6381–MAX6383 variants, but not with MAX809 due to differing package geometry and terminal assignment.
