Product details
Overview
MAX701CPA from Maxim Integrated is a +5V power-supply supervisory circuit with dual active-low and active-high reset outputs, 4.65V factory-trimmed threshold, 200ms minimum reset pulse width, and debounced manual-reset input. It ensures reliable µP reset during power-up, power-down, and brownout conditions in commercial-temperature embedded systems.
For engineers reviewing the MAX701CPA datasheet, MAX701CPA pinout, MAX701CPA application, or MAX701CPA equivalent, this page delivers verified electrical parameters, validated PDIP-8 package mapping, confirmed dual-reset functionality, and real-world use context for industrial controllers and intelligent instrumentation.
Technical Context
The MAX701CPA integrates a precision voltage comparator with internal 4.65V reference, RC-based timing network for guaranteed 200ms reset assertion, and complementary open-drain RESET and push-pull RESET outputs. Its MR input includes internal 5µA pullup and debouncing logic to suppress switch bounce.
Unlike the MAX702 (single reset output) and MAX700 (adjustable threshold via SENSE/CTL), the MAX701CPA provides both RESET and RESET simultaneously without external components-optimized for fixed +5V systems requiring polarity-flexible reset signaling to microprocessors or FPGAs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.65V ±150mV (factory-trimmed; ensures valid reset at VCC ≤ 4.50V) |
| Reset Pulse Width | 200–500ms (guaranteed minimum duration prevents premature µP release) |
| Supply Voltage Range | +1V to +15.5V (operates down to 1V for fail-safe reset state retention) |
| Output Types | RESET (open-drain, 16mA sink), RESET (push-pull, VCC−0.4V high) |
| Manual Reset Input | MR with 5µA internal pullup and hardware debouncing (no external RC needed) |
| Quiescent Current | 100–200µA (enables low-power monitoring in always-on subsystems) |
Pinout & Package
MAX701CPA is supplied in an 8-pin plastic dual-inline package (PDIP) with 0.3-inch body width and through-hole mounting. Pin spacing is 0.1 inch, compatible with standard DIP sockets and wave-solder processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | MR | Debounced manual-reset input; active-low, internally pulled up to VCC with 5µA |
| 2 | RESET | Inverted reset output; push-pull, drives high to VCC−0.4V, low to ≤0.4V |
| 3 | GND | Ground reference for all internal comparators and outputs |
| 4 | VCC | Primary supply input and monitored voltage source (+1V to +15.5V range) |
| 5 | RESET | Active-low reset output; open-drain, sinks up to 16mA at VCC = 5V |
| 6 | N.C. | No connection - left unconnected per datasheet; not internally bonded |
| 7 | N.C. | No connection - left unconnected per datasheet; not internally bonded |
| 8 | N.C. | No connection - left unconnected per datasheet; not internally bonded |
Key Features
| Feature | Design Value |
|---|---|
| Dual-complementary reset outputs | Simultaneous RESET (open-drain) and RESET (push-pull) eliminate level-shifting or inverters in mixed-logic systems |
| Factory-trimmed 4.65V threshold | Guarantees reset activation before +5V µP supply violates spec, no calibration required |
| 200ms minimum reset pulse | Ensures µP completes internal initialization before release, even under slow-rising VCC |
| Hardware-debounced MR input | Removes need for external RC filter or firmware debounce, reducing BOM count and layout area |
| Valid reset down to VCC = 1V | Maintains correct output state during deep brownout, preventing spurious release |
Applications
| Industrial Controllers | Intelligent Instruments |
|---|---|
Use Scenario: PLC mainboard monitoring +5V rail during factory automation cycles with frequent power cycling. IC Role / Device Role / Timing Role: Supervisory circuit asserting RESET until VCC stabilizes above 4.65V and holds for ≥200ms. Use Value: Prevents controller lockup during voltage sags caused by motor startup transients on shared 5V bus. | Use Scenario: Portable multimeter with µP-based ADC subsystem requiring deterministic boot sequence. IC Role / Device Role / Timing Role: Dual-output reset generator providing both active-low and active-high signals to separate logic domains. Use Value: Eliminates need for external inverter; RESET directly resets µP while RESET enables analog front-end power sequencing. |
| Computers | Critical µP Power Monitoring |
Use Scenario: Legacy x86-compatible single-board computer with ISA bus and discrete reset logic. IC Role / Device Role / Timing Role: Primary reset supervisor replacing discrete resistor-capacitor-timer networks. Use Value: Reduces component count by 4+ parts and improves reset timing accuracy vs. RC-based solutions. | Use Scenario: Medical infusion pump control module where unintended µP restart could compromise safety. IC Role / Device Role / Timing Role: Fail-safe power monitor asserting reset during brownout and holding reset for ≥200ms after recovery. Use Value: Guarantees µP remains held in reset until supply is fully stable, meeting IEC 62304 Class C requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar power-supply supervision applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX702CPA | Single active-low RESET output only; no RESET complement; identical threshold and timing | Lacks polarity flexibility - requires external inverter if system needs both reset polarities | Select when only one reset signal polarity is needed and board space is constrained |
| TPS3808G33DBVR | 3.3V fixed threshold; 200ms adjustable via external capacitor; higher quiescent current (4.5µA typical) | Designed for 3.3V systems; not drop-in for +5V monitoring without resistor divider | Choose for new 3.3V designs requiring programmable delay or lower supply current |
Compared with MAX702CPA and TPS3808G33DBVR, the MAX701CPA uniquely delivers dual-output reset capability in a pin-compatible PDIP-8 package for legacy +5V systems-enabling direct replacement of discrete reset circuits without layout changes or logic inversion.

FAQ
What is the reset threshold voltage of the MAX701CPA?
The MAX701CPA features a factory-trimmed reset threshold of 4.65V, with a guaranteed operating range of 4.50V to 4.75V over the full 0°C to +70°C temperature range. This ensures reliable reset assertion before a +5V microprocessor supply falls outside its specified tolerance, and the threshold is fixed-no external resistors or adjustments are required for standard +5V operation.
Does the MAX701CPA provide both active-low and active-high reset outputs?
Yes, the MAX701CPA provides two complementary reset outputs: an open-drain active-low RESET and a push-pull active-high RESET. This dual-output architecture eliminates the need for external inverters or level shifters in systems requiring both polarities-such as interfacing with legacy peripherals that expect active-high reset while the µP requires active-low.
What is the minimum reset pulse width guaranteed by the MAX701CPA?
The MAX701CPA guarantees a minimum reset pulse width of 200ms during power-up, power-down, and brownout events. This timing is internally generated and independent of external components, ensuring the microprocessor remains held in reset long enough to complete internal initialization-even under slow-rising or noisy supply conditions.
Can the MAX701CPA operate with supply voltages below +5V?
Yes, the MAX701CPA operates with VCC from +1V to +15.5V and maintains correct RESET/RESET output states down to VCC = 1V. This fail-safe behavior ensures the device continues asserting reset during deep brownouts, preventing spurious µP release-a key requirement for safety-critical and industrial applications.
Is the manual reset input (MR) on the MAX701CPA debounced internally?
Yes, the MR input of the MAX701CPA includes hardware debounce circuitry and an internal 5µA pullup current source. This eliminates the need for external RC filters or firmware-based debouncing, simplifying design and improving reliability in environments with mechanical switch noise or EMI.
