Product details
Overview
MAX701CPA+ from Maxim Integrated is a +5V power-supply supervisory circuit with dual active-low and active-high reset outputs, factory-trimmed 4.65V threshold, guaranteed reset assertion down to VCC = 1V, and debounced manual-reset input. It delivers 200ms minimum reset pulse width during power-up, power-down, and brownout conditions for microprocessor-based industrial controllers and embedded systems.
For engineers reviewing the MAX701CPA+ datasheet, MAX701CPA+ pinout, MAX701CPA+ application, or MAX701CPA+ equivalent, key selection factors include its dual-reset output architecture, 8-pin PDIP package with lead-free compliance (+ suffix), 100µA typical supply current, and compatibility with +5V digital systems requiring reliable, no-adjustment power monitoring.
Technical Context
The MAX701CPA+ integrates a precision voltage comparator with internal 4.65V reference, RC timing network for fixed 200ms+ reset timeout, and dual complementary open-drain (RESET) and push-pull (RESET) output drivers. Its MR input includes internal 5µA pullup and debouncing logic to suppress switch bounce.
Unlike the MAX702 (single RESET), the MAX701CPA+ provides both RESET and RESET outputs simultaneously-enabling direct interface to processors requiring either active-low or active-high reset assertion without external inversion. The device operates across 0°C to +70°C and supports VCC from +1V to +15.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.65V ±150mV (factory-trimmed for +5V systems; ensures deterministic reset at valid logic supply level) |
| Reset Pulse Width | 200–500ms (guaranteed minimum 200ms ensures full µP initialization before release) |
| Supply Current | 100–200µA (ultra-low quiescent draw enables use in battery-backed or always-on monitoring) |
| VCC Valid Range | +1V to +15.5V (reset remains asserted down to 1V; supports brownout detection below logic threshold) |
| MR Input Threshold | 0.7V (TTL-compatible manual reset trigger; internal 5µA pullup eliminates external resistor) |
| RESET Output Type | Push-pull (drives high/low actively; no external pullup required for RESET signal) |
| RESET Output Type | Open-drain (requires external pullup; enables wired-OR reset bus sharing across multiple devices) |
Pinout & Package
MAX701CPA+ is supplied in an 8-pin plastic DIP (PDIP) package with 0.3-inch body width and through-hole mounting. Pin 1 is marked by a notch or dot; pin numbering follows standard counter-clockwise convention from top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 MR | Manual Reset Input | Active-low debounced input with internal 5µA pullup; asserts reset when pulled ≤0.7V |
| 2 - | No Connection | Not bonded internally; must be left unconnected |
| 3 - | No Connection | Not bonded internally; must be left unconnected |
| 4 GND | Ground Reference | Primary return path for all internal circuits and output drivers |
| 5 RESET | Active-Low Reset Output | Open-drain output; sinks ≥16mA at VCC=5V; requires external pullup |
| 6 RESET | Active-High Reset Output | Push-pull output; drives high to VCC−0.4V and low to ≤0.4V; no external components needed |
| 7 - | No Connection | Not bonded internally; must be left unconnected |
| 8 VCC | Power Supply Input | +1V to +15.5V operation; powers internal comparator, timer, and output stages |
Key Features
| Feature | Design Value |
|---|---|
| Dual Complementary Reset Outputs | Simultaneous RESET (open-drain) and RESET (push-pull) eliminate need for external inverters or pullups in mixed-logic systems |
| 200ms Minimum Reset Pulse | Guaranteed duration ensures complete microprocessor initialization and peripheral settling before release |
| Debounced Manual-Reset Input | Internal hardware debounce removes mechanical switch bounce without software or RC filters |
| Factory-Trimmed 4.65V Threshold | ±150mV accuracy over 0°C to +70°C avoids calibration and supports plug-and-play +5V system integration |
| Low 100µA Supply Current | Enables continuous supervision in power-sensitive applications such as battery-backed real-time clocks or standby monitors |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar power-supply monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX702CPA+ | Single active-low RESET output only; no complementary RESET output; identical pinout except pin 6 is NC | Suitable where only one reset polarity is required and board space allows omission of external inverter | Select MAX702CPA+ to reduce cost and complexity when dual-output functionality is unnecessary |
| TPS3808G18DBVR | Adjustable threshold (1.8V fixed option); 200ms fixed delay; open-drain RESET only; SOT-23-6 package | Better suited for low-voltage (1.8V–3.3V) systems; lacks push-pull output and manual reset debounce | Choose TPS3808G18DBVR for compact, low-voltage designs where MR debounce and dual outputs are not required |
Compared with MAX702CPA+, the MAX701CPA+ adds critical dual-output flexibility without layout change; versus TPS3808G18DBVR, it offers superior +5V system integration with built-in debounce and push-pull drive-reducing external component count and improving noise immunity in industrial environments.

FAQ
What is the reset threshold voltage of the MAX701CPA+ and how is it trimmed?
The MAX701CPA+ features a factory-trimmed reset threshold of 4.65V with ±150mV tolerance over 0°C to +70°C. This value is laser-trimmed during production to ensure accuracy without external components. The threshold is referenced to VCC and remains stable across temperature, making the MAX701CPA+ ideal for +5V systems where precise brownout detection is required.
Does the MAX701CPA+ require external components to operate with a +5V supply?
No, the MAX701CPA+ requires zero external components when used with a +5V supply. Its internal voltage reference, timing capacitor, and debounced MR input eliminate the need for external resistors, capacitors, or pullups-reducing BOM cost and PCB area. This self-contained operation is explicitly validated in the MAX701CPA+ datasheet for +5V-powered circuits.
What is the function of pin 6 (RESET) on the MAX701CPA+ and how does it differ from pin 5 (RESET)?
Pin 6 (RESET) on the MAX701CPA+ is an active-high push-pull output that drives high to VCC−0.4V and low to ≤0.4V, requiring no external pullup. Pin 5 (RESET) is an active-low open-drain output that must be pulled up externally. This dual-output architecture allows the MAX701CPA+ to directly drive both TTL- and CMOS-compatible reset inputs without additional logic.
Can the MAX701CPA+ monitor supply voltages below +5V, such as +3.3V or +2.5V?
The MAX701CPA+ is optimized for +5V systems and guarantees correct reset behavior only when VCC ≥ +1V. Its 4.65V threshold is fixed and not adjustable; therefore, it is not suitable for monitoring +3.3V or +2.5V rails. For lower-voltage monitoring, the MAX700 series (with SENSE input) or dedicated low-voltage supervisors like the TPS3808 should be used instead of the MAX701CPA+.
What does the '+' suffix in MAX701CPA+ indicate, and is it RoHS compliant?
The '+' suffix in MAX701CPA+ indicates lead(Pb)-free packaging per JEDEC J-STD-609, with matte-tin plating and RoHS-compliant materials. This marking is specified in Maxim's ordering information and verified in the package documentation. The MAX701CPA+ meets EU RoHS Directive 2011/65/EU and is suitable for environmentally regulated industrial and medical applications.
