Product details
Overview
ADM707ANZ from Analog Devices is a precision 5 V microprocessor supervisory circuit with active-high reset output, 4.65 V supply voltage monitor threshold, 200 ms reset pulse width, 190 μA quiescent current, and power-fail comparator (PFI/PFO) for low-battery or preregulator monitoring in embedded control systems.
For engineers reviewing the ADM707ANZ datasheet, ADM707ANZ pinout, ADM707ANZ application, or ADM707ANZ equivalent, this page delivers verified functional identity, PDIP-8 package mapping, reset timing behavior, PFI comparator interface details, and direct alternatives for industrial microcontroller power monitoring designs.
Technical Context
The ADM707ANZ implements a dedicated voltage-monitoring architecture with a precision 4.65 V threshold detector and internal hysteresis (40 mV), guaranteeing valid RESET assertion down to VCC = 1 V. Its active-high RESET output complements the standard active-low signal, enabling direct interface with processors requiring high-true reset logic.
It integrates a 1.25 V reference-based power-fail comparator (PFI input, PFO output) for early warning of supply droop or battery depletion, and includes a debounced TTL/CMOS-compatible manual reset input (MR) with 250 μA internal pull-up - no external components required for basic operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.65 V ±150 mV - triggers reset during brownout when 5 V rail drops below safe microprocessor operating level |
| Reset Pulse Width | 200 ms typical - ensures sufficient hold time for full microprocessor power-up stabilization |
| Quiescent Current | 190 μA max - enables long-term battery-backed operation without significant drain |
| VCC Validity Range | 1.0 V to 5.5 V - guarantees functional reset assertion even during deep undervoltage ramp-up or shutdown |
| PFI Threshold | 1.25 V ±50 mV - sets trip point for external supply monitoring via resistive divider |
| MR Input Logic | TTL/CMOS compatible, 0.8 V low / 2.0 V high - supports direct switch or logic-level reset initiation |
| RESET Output Type | Active-high open-drain - requires external pull-up; sinks 1.2 mA at 0.4 V for robust noise immunity |
Pinout & Package
ADM707ANZ is housed in an 8-lead narrow-body plastic dual-in-line package (PDIP, JEDEC MS-001-BA, N-8), with 0.300-inch width, 0.100-inch lead pitch, and through-hole mounting compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - MR | Manual Reset Input | Debounced TTL/CMOS input; asserted low <0.8 V triggers 200 ms reset pulse; internally pulled up at 250 μA |
| 2 - VCC | Power Supply Input | 5 V nominal supply; decoupling capacitor (0.1 μF) required between VCC and GND for noise immunity |
| 3 - GND | Ground Reference | 0 V return for all analog and digital functions; must be low-impedance connection |
| 4 - PFI | Power Fail Input | Noninverting input to 1.25 V comparator; monitors external supply via resistor divider; connect to GND if unused |
| 5 - PFO | Power Fail Output | Active-low open-drain output; goes low when PFI < 1.25 V; requires external pull-up for interrupt signaling |
| 6 - NC | No Connect | Internally unconnected; must remain floating or grounded per layout best practice |
| 7 - RESET | Active-High Reset Output | Complementary to active-low RESET; drives high after reset timeout; open-drain, 1.2 mA sink capability |
| 8 - RESET | Active-Low Reset Output | Primary reset signal; goes low during power-up/brownout/MR assertion; guaranteed valid down to VCC = 1 V |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RESET below 1 V VCC | Ensures fail-safe microprocessor hold-down during deep undervoltage conditions without external pull-down |
| Dual RESET polarity outputs | Provides both active-high and active-low reset signals on same die - eliminates need for external inverter |
| Integrated power-fail comparator | Enables early-warning detection of supply droop or battery depletion using only two external resistors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM707ARZ | Same electrical specs and functionality; SOIC-8 (R-8) surface-mount package instead of PDIP-8 | Suitable for automated SMT assembly; requires different footprint and reflow profile | Select ADM707ARZ for volume production with pick-and-place manufacturing; ADM707ANZ remains optimal for prototyping, through-hole boards, or legacy DIP layouts. |
| MAX707CPA+ | Pin-compatible 8-pin PDIP; 4.65 V reset threshold and active-high RESET; 250 ms reset timeout (vs. 200 ms) | Higher reset pulse width increases margin for slow-ramping supplies but may delay processor initialization | Choose MAX707CPA+ only if longer reset hold time is explicitly required; verify timing compatibility with target MCU's reset setup requirements. |
Compared with ADM707ANZ, ADM707ARZ offers identical supervision performance in a smaller surface-mount form factor, while MAX707CPA+ provides legacy pin compatibility with extended reset duration - neither is drop-in without layout or timing validation.

FAQ
What is the reset threshold voltage of the ADM707ANZ, and how does it behave during brownout?
The ADM707ANZ has a nominal reset threshold of 4.65 V with ±150 mV tolerance and 40 mV hysteresis. During brownout, RESET (active-low) asserts when VCC falls below this threshold and remains asserted until VCC rises above 4.65 V + 40 mV, then holds for 200 ms. The ADM707ANZ guarantees valid RESET output down to VCC = 1 V, ensuring reliable microprocessor hold-down even during deep undervoltage conditions.
Does the ADM707ANZ include a watchdog timer function?
No, the ADM707ANZ does not include a watchdog timer. It belongs to the ADM707/ADM708 variant group, which omits the WDI and WDO pins present in ADM705/ADM706. Instead, ADM707ANZ provides dual RESET outputs (active-low and active-high) and retains the PFI/PFO power-fail comparator. For watchdog capability, engineers must select ADM705ANZ or ADM706ANZ.
How is the power-fail comparator used in the ADM707ANZ, and what external components are needed?
The ADM707ANZ's PFI input connects to a resistive divider from an external supply (e.g., 12 V battery or preregulator output), scaling it to trip at 1.25 V. When PFI falls below this threshold, PFO (open-drain) pulls low to signal power failure. Only two resistors are required - no op-amps or comparators needed. If unused, PFI must be tied to GND. The ADM707ANZ datasheet provides hysteresis design equations for noise immunity.
What package type and pin count does the ADM707ANZ use, and is it RoHS compliant?
The ADM707ANZ uses an 8-lead narrow-body plastic dual-in-line package (PDIP, JEDEC MS-001-BA, N-8) with 0.300-inch width and through-hole mounting. The "Z" suffix in ADM707ANZ indicates RoHS compliance per EU Directive 2011/65/EU. Lead finish is matte tin, and the device meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) for unlimited floor life.
Can the ADM707ANZ drive a microprocessor reset pin directly, and what are the drive strength limits?
Yes, the ADM707ANZ can drive most microprocessor reset pins directly. Its active-low RESET output sinks up to 3.2 mA at 0.4 V (VCC ≥ 4.75 V) and remains valid down to VCC = 1 V. The active-high RESET output sinks 1.2 mA at 0.4 V and requires an external pull-up resistor (typically 4.7 kΩ to VCC). For bidirectional reset lines, a current-limiting resistor (e.g., 4.7 kΩ) is recommended to prevent contention.
