Product details
Overview
MAX701EPA+ from Maxim Integrated is a precision power-supply supervisory circuit for +5V microprocessor systems, providing dual active-low and active-high reset outputs with guaranteed valid state down to VCC = 1V, 4.65V factory-trimmed reset threshold, ≥200ms reset pulse width, and debounced manual-reset input. It operates across –40°C to +85°C in 8-pin PDIP packaging and is used in industrial controllers and embedded systems requiring reliable power-on/off reset sequencing.
For engineers reviewing the MAX701EPA+ datasheet, MAX701EPA+ pinout, MAX701EPA+ application, or MAX701EPA+ equivalent, key selection criteria include its dual RESET/RESET outputs, guaranteed reset assertion below 4.65V, 200ms minimum pulse width, manual reset debounce, and extended temperature operation without external components.
Technical Context
The MAX701EPA+ implements a voltage-monitoring comparator with internal 4.65V reference and built-in hysteresis (~30mV), ensuring noise-immune reset assertion during supply ramp-up/down. Its dual complementary outputs drive both active-low and active-high reset inputs on µP or logic circuits simultaneously.
It features a debounced MR input with 5µA internal pullup and threshold at 0.7V, enabling pushbutton-initiated system reset without external RC filtering. The device guarantees correct output state for VCC ≥ 1V and supports safe reset hold until stable operation is confirmed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.65V ±150mV (factory-trimmed for +5V systems; ensures deterministic reset at nominal supply) |
| Reset Pulse Width | 200–500ms (guarantees sufficient time for µP initialization before release) |
| Operating Voltage Range | VCC = 1V to 5.5V (valid reset output down to 1V enables brownout detection) |
| Supply Current | 100–200µA (ultra-low quiescent current preserves system standby efficiency) |
| Temperature Range | –40°C to +85°C (supports industrial-grade deployment without derating) |
| MR Input Threshold | 0.7V (compatible with TTL/CMOS logic levels for robust manual reset activation) |
| Output Drive Strength | RESET: 16mA sink / 3.2mA source; RESET: 3.2mA sink / 3.2mA source (directly interfaces µP reset pins) |
Pinout & Package
MAX701EPA+ is housed in an 8-pin plastic DIP (PDIP) package with 0.3-inch body width and through-hole mounting. Pin 1 is MR (manual reset input), Pin 4 is GND, Pin 5 is RESET (active-low), Pin 6 is RESET (active-high), Pin 8 is VCC. Pins 2, 3, and 7 are no-connect (N.C.) per MAX701 pin configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - MR | Manual Reset Input | Debounced low-active input with 5µA internal pullup; asserts reset when pulled ≤0.7V |
| 4 - GND | Ground Reference | Common return path for all internal comparators and output drivers |
| 5 - RESET | Active-Low Reset Output | Open-drain output sinks up to 16mA; requires external pullup for µP-compatible reset signal |
| 6 - RESET | Active-High Reset Output | Push-pull output sources/sinks 3.2mA; directly drives high-true reset inputs |
| 8 - VCC | Power Supply Input | +5V supply and monitored voltage source; valid operation from 1V to 5.5V |
Key Features
| Feature | Design Value |
|---|---|
| Dual Complementary Reset Outputs | Simultaneous RESET (active-low) and RESET (active-high) eliminate need for external inverters in mixed-logic systems |
| Guaranteed Valid Reset Below 1V | Ensures deterministic reset assertion even during deep brownout or battery sag conditions |
| Factory-Trimmed 4.65V Threshold | Eliminates calibration components and improves production yield for +5V applications |
| Debounced Manual Reset Input | Internal timing removes need for external RC filter, reducing BOM count and PCB area |
| 200ms Minimum Reset Pulse Width | Meets µP reset timing requirements without external monostable circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar power-supply monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3808G33DBVR | Single active-low reset output; 3.3V fixed threshold; 2% accuracy; 350ms default timeout | Designed for 3.3V systems; lacks complementary RESET output and manual reset debounce | Select when only one reset polarity is needed and system uses 3.3V supply with tighter threshold tolerance |

FAQ
What is the reset threshold voltage of the MAX701EPA+?
The MAX701EPA+ has a factory-trimmed reset threshold of 4.65V with ±150mV tolerance over the full –40°C to +85°C temperature range. This value is specified for both power-up and power-down conditions and ensures deterministic reset assertion in +5V systems without external calibration components.
Does the MAX701EPA+ provide both active-low and active-high reset outputs?
Yes, the MAX701EPA+ provides complementary outputs: pin 5 is RESET (active-low, open-drain), and pin 6 is RESET (active-high, push-pull). This dual-output architecture eliminates the need for external inverters when interfacing with µPs or logic that require either polarity, and both outputs are asserted synchronously during reset events.
What is the minimum VCC voltage at which the MAX701EPA+ guarantees valid reset output states?
The MAX701EPA+ guarantees correct RESET/RESET output states for VCC voltages down to +1V, as verified across the full operating temperature range. This capability supports robust brownout detection and ensures system reset remains functional even during severe supply droop or battery depletion scenarios.
Is manual reset debouncing implemented internally in the MAX701EPA+?
Yes, the MAX701EPA+ includes internal debouncing for the MR (pin 1) input. No external RC network is required-the device filters mechanical switch bounce digitally, ensuring clean reset assertion regardless of pushbutton contact chatter. The MR threshold is 0.7V with a 5µA internal pullup current.
What package type and RoHS status does the MAX701EPA+ use?
The MAX701EPA+ is supplied in an 8-pin plastic DIP (PDIP) package with lead(Pb)-free construction, indicated by the "+" suffix. It meets RoHS Directive 2011/65/EU and is rated for –40°C to +85°C operation. The package outline conforms to Maxim's P8+2 standard (outline 21-0143).
