Product details
Overview
MAX6807XR46-T from Maxim Integrated is a precision voltage detector IC designed for reliable power-supply monitoring in microprocessor-based systems. It features a factory-preset 4.6V ±2% reset threshold, active-high push-pull RESET output, operates down to VCC = 1.2V, draws only 35µA supply current, and is housed in a 3-pin SC70 package - enabling compact, low-power brownout detection in portable and embedded controllers.
For engineers reviewing the MAX6807XR46-T datasheet, MAX6807XR46-T pinout, MAX6807XR46-T application, or MAX6807XR46-T equivalent, this device serves as a critical supervisory component for ensuring deterministic reset assertion during power-up, brownout, and power-down sequences in battery-powered instrumentation and µP systems requiring tight voltage tolerance and minimal quiescent current.
Technical Context
The MAX6807XR46-T implements a precision bandgap-based voltage reference comparator with internal hysteresis (VHYST = 0.02–0.03 × VTH−), ensuring stable reset switching without oscillation near the 4.6V threshold. Its active-high push-pull output drives logic-high when VCC ≥ VTH+ and asserts logic-low when VCC falls below VTH−.
It guarantees valid RESET output down to VCC = 1.2V (VOH ≥ 0.8×VCC at ISOURCE = 20µA), supports transient immunity up to 100V/µs on VCC, and requires no external components - delivering plug-and-play reset supervision with fixed timing behavior (30µs typical VCC-fall delay) and ±30ppm/°C temperature coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.60V ±2% (VTH− = 4.508–4.692V at +25°C); ensures reset assertion before system ICs drop below minimum operating voltage. |
| Supply Current | 35µA typical at VCC = 3.6V; enables multi-year battery life in portable equipment with continuous monitoring. |
| Output Type | Active-high push-pull RESET; eliminates need for external pullup and directly interfaces with standard CMOS inputs. |
| VCC Operating Range | 1.2V to 5.5V over −40°C to +85°C; supports operation through deep brownout while maintaining output validity. |
| Reset Delay | 30µs typical (VCC falling at 1mV/µs); provides fast, deterministic response to supply collapse without excessive latency. |
| Hysteresis | 0.02–0.03 × VTH− (≈92–140mV); prevents chatter during slow-rising/falling supplies or noisy rail conditions. |
| Tempco | ±30ppm/°C; maintains threshold stability across industrial temperature range without calibration. |
Pinout & Package
MAX6807XR46-T is packaged in a 3-pin SC70 (X3-2 outline), measuring 2.0mm × 2.1mm × 0.95mm, with gull-wing leads and RoHS-compliant finish. The package is tape-and-reel compatible (2500 pcs/reel) and optimized for high-density PCB layouts.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RESET | Active-high push-pull output; drives logic-high when VCC ≥ VTH+, logic-low when VCC < VTH−; sinks/source ≤20mA. |
| 2 | GND | Analog ground reference; must be connected to system ground plane with low-impedance path to minimize noise coupling. |
| 3 | VCC | Supply input; accepts 1.2V–5.5V; internally powers reference, comparator, and output stage; rated for −0.3V to +6.0V absolute max. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed 4.6V threshold | Eliminates external resistor networks and calibration steps - reduces BOM count and assembly cost. |
| 35µA ultra-low ICC | Enables always-on supervision in energy-constrained devices such as handheld scanners and sensor nodes. |
| 1.2V minimum VCC operation | Ensures reset remains asserted until supply recovers sufficiently to support µP core logic, preventing premature wake-up. |
| Internal hysteresis | Prevents false resets during marginal supply conditions - no external capacitor or feedback required. |
| Immunity to VCC transients | Withstands negative-going spikes up to 100V/µs without spurious reset generation - improves system robustness in noisy environments. |
Applications
| Portable Barcode Scanners | Industrial Microcontroller Supervision |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6806XR46-T | Identical 4.6V ±2% threshold and SC70 package, but features active-low push-pull RESET output. | Requires inverted logic interpretation at µP reset input; incompatible with systems expecting active-high assertion. | Select when host µP reset pin is active-low and board layout cannot accommodate level-shifting. |
| TLV803EB26DBZR | 2.6V threshold, SOT-23-3 package, 36µA ICC, but lacks guaranteed operation below 1.5V and has no manual reset option. | Not suitable for 4.6V rail monitoring; intended for lower-voltage domains like 3.3V or 2.5V logic supplies. | Choose only if redesigning for lower-threshold supervision and accepting reduced low-VCC validity margin. |
Compared with MAX6806XR46-T and TLV803EB26DBZR, the MAX6807XR46-T uniquely delivers active-high reset signaling with full 1.2V operational assurance and factory-calibrated 4.6V accuracy - making it the optimal choice for legacy µP designs requiring direct-compatible, no-glue logic-level reset assertion.

FAQ
What is the exact reset threshold voltage of the MAX6807XR46-T?
The MAX6807XR46-T has a factory-preset nominal reset threshold of 4.60V, with guaranteed accuracy of ±2% (4.508V to 4.692V) at +25°C. This threshold applies to VCC falling conditions (VTH−), and includes built-in hysteresis to prevent chatter during slow supply transitions. The MAX6807XR46-T maintains this specification across its full −40°C to +85°C operating range with a tempco of ±30ppm/°C.
Does the MAX6807XR46-T support operation below 2.0V?
Yes - the MAX6807XR46-T guarantees valid active-high RESET output down to VCC = 1.2V, with VOH ≥ 0.8×VCC at ISOURCE = 20µA. This allows the MAX6807XR46-T to remain functional during deep brownout events where other supervisors fail, ensuring continued reset assertion until the supply recovers sufficiently to support downstream logic. Operation below 1.2V is not specified.
What package type and dimensions does the MAX6807XR46-T use?
The MAX6807XR46-T uses a 3-pin SC70 package (outline X3-2), measuring 2.0mm × 2.1mm × 0.95mm with gull-wing leads. It is supplied in tape-and-reel format (2500 pieces per reel) and complies with RoHS requirements. The SC70 footprint matches industry-standard land pattern 90-0208 and is compatible with automated SMT assembly processes.
How does the MAX6807XR46-T differ from the MAX6806XR46-T?
The MAX6807XR46-T and MAX6806XR46-T share identical 4.6V ±2% threshold, SC70 package, and electrical specs - but differ exclusively in reset polarity: MAX6807XR46-T provides an active-high push-pull RESET output, while MAX6806XR46-T provides active-low. This makes the MAX6807XR46-T directly compatible with µPs requiring high-true reset assertion without external inversion.
Is a manual reset input available on the MAX6807XR46-T?
No - the MAX6807XR46-T does not include a manual reset (MR) input. Manual reset functionality is only available in the 4-pin SOT143 variants (e.g., MAX6807US46-T), which integrate an MR pin with internal 80kΩ pulldown. The MAX6807XR46-T is a 3-pin SC70 device with RESET, GND, and VCC only - simplifying layout but requiring external circuitry for operator-initiated reset.
