Product details
Overview
AP1704AWG-7 from Diodes Incorporated is a 3-pin microprocessor reset supervisor IC with active-high push-pull RESET output, 2.93 V reset threshold (±1.5% at 25°C), 240 ms minimum reset timeout, 20 µA typical supply current, and guaranteed operation down to VCC = 1 V. It monitors +3.0 V digital power rails in embedded controllers and portable systems requiring reliable brownout detection.
For engineers reviewing the AP1704AWG-7 datasheet, AP1704AWG-7 pinout, AP1704AWG-7 application, or AP1704AWG-7 equivalent, key selection criteria include reset threshold accuracy (±1.5%), immunity to sub-100 µs VCC transients, push-pull drive capability (800 µA source / 1.2 mA sink), and SC59 package compatibility with space-constrained PCB layouts.
Technical Context
The AP1704AWG-7 implements a precision bandgap-based voltage comparator with internal 240 ms timer and push-pull output stage. Its reset assertion logic triggers when VCC falls below 2.93 V and holds RESET high for ≥240 ms after VCC recovers above threshold.
Designed for +3.0 V systems, it features 30 ppm/°C temperature coefficient on reset threshold, operates across –40°C to +105°C junction temperature, and maintains valid RESET output state for VCC ≥ 1 V - enabling robust power sequencing in battery-powered instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.93 V ±1.5% at 25°C - matches nominal +3.0 V supply with 2.3% headroom before reset activation |
| Reset Timeout | 240 ms min - ensures µP completes full power-up initialization before release |
| Supply Current | 20 µA typ. - enables multi-year battery life in always-on monitoring circuits |
| VCC Operating Range | 1.0 V to 5.5 V - supports valid reset assertion during deep brownout down to 1 V |
| Output Type | Push-pull active-high - drives CMOS inputs directly without external pull-up resistor |
| Transient Immunity | 100 µs max glitch duration at 100 mV overdrive - rejects common switching noise on VCC rail |
| Tempco | 30 ppm/°C - limits threshold drift to ±14.7 mV over –40°C to +105°C range |
Pinout & Package
AP1704AWG-7 is housed in a lead-free, green SC59-3L package (2.90 × 1.30 × 0.95 mm), compatible with standard SOT-23 footprint layouts per Diodes Inc. AP02001 pad guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for internal comparator and output driver; must be low-impedance connection to system ground plane |
| 2 | RESET | Active-high push-pull output; sinks 1.2 mA / sources 800 µA; asserts high during reset condition |
| 3 | VCC | Power input; supplies internal circuitry and defines monitored voltage rail; bypass with 0.1 µF capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Precision reset threshold | 2.93 V ±1.5% - eliminates need for external trimming resistors in +3.0 V systems |
| Guaranteed reset validity | Valid RESET output for VCC ≥ 1 V - ensures deterministic behavior during deep undervoltage events |
| No external components required | Self-contained supervisory function - reduces BOM count and PCB area vs. discrete reset solutions |
| Low quiescent current | 20 µA typical - extends battery runtime in portable instruments and remote sensors |
| SC59-3L package | RoHS-compliant, green, 3-pin surface-mount - supports automated assembly and high-density routing |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset supervision applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| APX810S23-30 | 2.93 V threshold, 200 ms timeout, SOT23-3 package, 1.5 µA max ICC | Lower supply current enables ultra-low-power designs; shorter timeout may require firmware adaptation | Select for battery life-critical applications where 40 ms shorter reset pulse is acceptable |
| TPS3808G30DBVR | 2.93 V threshold, 200 ms timeout, 1.8 µA max ICC, wider VCC range (0.8–6.0 V) | Supports direct monitoring of Li-ion cells; higher cost and larger SOT23-6 footprint | Choose when monitoring sub-1 V rails or requiring TI's enhanced ESD protection (4 kV HBM) |
Compared with APX810S23-30 and TPS3808G30DBVR, AP1704AWG-7 offers longer reset timeout (240 ms vs. 200 ms) for conservative µP initialization, SC59-3L package for tighter board space, and proven transient immunity in automotive-grade environments - making it optimal for industrial control where timing margin and layout density are prioritized over ultra-low ICC.

FAQ
What is the exact reset threshold voltage for AP1704AWG-7 and how is it marked?
The AP1704AWG-7 has a nominal reset threshold of 2.93 V with ±1.5% tolerance at 25°C. Per Diodes Inc. marking code, "E" in position 2 of the top-side marking (e.g., "E7") denotes the "E" variant corresponding to 2.93 V. This is confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables of Rev. 2 datasheet (Jan 2007), where AP1701/2/3/4E is explicitly defined as 2.87/2.93/2.99 V min/typ/max.
Does AP1704AWG-7 support active-high reset with push-pull output, and what are its drive capabilities?
Yes, AP1704AWG-7 provides an active-high push-pull RESET output (pin 2). It sources up to 800 µA at VCC – 1.5 V and sinks up to 1.2 mA at 0.4 V, enabling direct interface with standard CMOS inputs without external pull-up resistors. This is specified in the Electrical Characteristics table under VOH and VOL conditions for AP1702/4 variants.
Is AP1704AWG-7 suitable for operation below 1.0 V, and what happens to RESET output at low VCC?
No - RESET output is only guaranteed valid for VCC ≥ 1.0 V. Below 1.0 V, the output becomes high-impedance (open-circuit) and cannot actively drive logic states. The datasheet explicitly states "RESET is guaranteed to be a logic low for VCC > 1V" and notes that for VCC < 1V, external pull-down may be needed if deterministic low state is required during deep undervoltage.
Why is AP1704AWG-7 marked "NOT RECOMMENDED FOR NEW DESIGN", and what is the recommended replacement?
Diodes Inc. designates AP170x series as "NOT RECOMMENDED FOR NEW DESIGN" due to obsolescence roadmap, recommending APX809/810 series instead. APX810S23-30 is the functional replacement: same 2.93 V threshold, SOT23-3 package, but with lower ICC (1.5 µA max), improved tempco, and extended qualification. Migration requires validation of 200 ms timeout vs. AP1704AWG-7's 240 ms.
