Product details
Overview
AP1701AWG-7 from Diodes Incorporated is a 3-pin active-low microprocessor reset supervisor IC in SC59 package, with 4.63V reset threshold, 240ms minimum reset timeout, 20µA typical supply current, and guaranteed reset validity down to VCC = +1V. It monitors +5V digital power rails in embedded controllers and portable equipment to prevent erroneous code execution during brownout or power-up.
For engineers reviewing the AP1701AWG-7 datasheet, AP1701AWG-7 pinout, AP1701AWG-7 application, or AP1701AWG-7 equivalent, key selection criteria include reset threshold accuracy (±0.09V), push-pull output drive capability (1.2mA sink), temperature coefficient (30 ppm/°C), transient immunity (100µs @ 100mV overdrive), and RoHS-compliant lead-free SC59 packaging.
Technical Context
The AP1701AWG-7 implements a precision voltage comparator with internal reference and a monostable delay circuit to generate a minimum 240ms active-low reset pulse after VCC rises above 4.63V. Its push-pull output eliminates external pull-up resistors and ensures defined logic states across the full 1.0–5.5V operating range.
Designed for immunity to fast VCC transients, it ignores negative-going glitches ≤100µs when overdriven by 100mV below threshold. The reset comparator remains functional down to VCC = 1V, and output voltage low is specified at 0.3V (ISINK = 1.2mA), enabling direct interface with 5V CMOS inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.63V ±0.09V - precisely matches +5V supply monitoring with 2% tolerance |
| Reset Timeout | 240ms min - ensures µP initialization completes before release |
| Supply Current | 20µA typ. - enables battery operation in portable systems |
| VCC Operating Range | 1.0V to 5.5V - guarantees reset assertion even during deep brownout |
| Output Type | Push-pull active-low - drives RESET line directly without external components |
| Tempco | 30 ppm/°C - maintains threshold stability across –40°C to +105°C |
| Transient Immunity | 100µs max glitch duration @ 100mV overdrive - suppresses noise-induced false resets |
Pinout & Package
AP1701AWG-7 is housed in a 3-pin SC59 (SC59-3L) surface-mount package with gull-wing leads, 2.7–3.0mm body length, and 1.9mm width per datasheet AP1701/2/3/4 Rev. 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for comparator and output stage; must be low-impedance connection |
| 2 | VCC | Power input pin; supplies internal reference and logic; bypass capacitor required |
| 3 | RESET | Active-low push-pull reset output; sinks ≥1.2mA at 0.3V, compatible with standard CMOS inputs |
Key Features
| Feature | Design Value |
|---|---|
| Precision reset threshold | 4.63V ±0.09V - eliminates need for external trimming in +5V systems |
| No external components required | Integrated reference, comparator, and delay - reduces BOM count and PCB area |
| Guaranteed reset validity to VCC = 1V | Ensures deterministic behavior during severe brownout, unlike open-drain alternatives |
| Lead-free and green packaging | RoHS-compliant SC59-3L with matte tin finish - meets environmental compliance requirements |
| High noise immunity | 100µs glitch rejection at 100mV overdrive - prevents spurious resets in noisy environments |
Applications
| Industrial Controllers | Portable Medical Devices |
|---|---|
Use Scenario: PLC I/O modules powered from regulated +5V rails subject to intermittent brownouts during field deployment. IC Role / Device Role / Timing Role: Microprocessor reset supervisor asserting active-low signal until VCC stabilizes >4.63V for ≥240ms. Use Value: Prevents firmware corruption during unstable mains conditions; push-pull output ensures immediate release without pull-up resistor. |
Use Scenario: Battery-powered glucose meter with low-power µC requiring reliable startup under declining Li-ion voltage. IC Role / Device Role / Timing Role: Power-on reset generator that remains functional down to VCC = 1V and draws only 20µA quiescent current. Use Value: Extends usable battery life while guaranteeing deterministic boot sequence across full discharge curve. |
| Automotive Body Control Modules | Network Edge Routers |
Use Scenario: 12V-to-5V converted subsystem exposed to load-dump transients and cold-crank voltage sags. IC Role / Device Role / Timing Role: Brownout detector rejecting <100µs VCC glitches while asserting reset for ≥240ms after recovery. Use Value: Maintains system integrity during automotive electrical disturbances without false triggering. |
Use Scenario: Fanless enterprise router with multiple ASICs requiring synchronized reset on power-up. IC Role / Device Role / Timing Role: Single-supply reset monitor for +5V rail feeding FPGA configuration and management MCU. Use Value: Eliminates discrete RC reset networks; 30 ppm/°C tempco ensures timing consistency across operating temperature range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset supervision applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| APX809S24-7 | 2.4V fixed threshold, SOT23-3, 140ms reset timeout, 0.5µA IQ | Targeted for +3.3V/2.5V systems; not suitable for +5V monitoring | Select only if redesigning for lower supply voltage and ultra-low power is critical |
| TPS3808G125DBVR | 1.25V threshold, adjustable via external resistor, 200ms timeout, 1.1µA IQ | Requires external component for threshold setting; higher design complexity | Choose when programmable threshold or tighter tolerance (<0.5%) is required |
Compared with AP1701AWG-7, APX809S24-7 offers lower power but mismatches the 4.63V +5V requirement, while TPS3808G125DBVR provides adjustability at the cost of added BOM and layout overhead-neither serves as drop-in replacement for legacy +5V supervisory use.

FAQ
Is AP1701AWG-7 still in production despite the "Not Recommended for New Design" notice?
Yes, AP1701AWG-7 remains actively manufactured and stocked by Diodes Incorporated and authorized distributors. The "Not Recommended for New Design" advisory reflects the availability of newer-generation alternatives like APX809/810 with improved specs, but does not indicate imminent discontinuation. Aetrix Electronics maintains inventory and supports long-term supply for legacy designs.
Can AP1701AWG-7 drive a reset input requiring 20mA sink current?
No. AP1701AWG-7's RESET pin is rated for 1.2mA sink current at 0.3V (VOL), per datasheet Electrical Characteristics. Driving loads exceeding this requires an external buffer or MOSFET. It is designed for direct interface with standard CMOS µP reset inputs, which typically draw <100µA and accept 0.3V as valid logic low.
What is the recommended bypass capacitor value and placement for AP1701AWG-7?
A 0.1µF ceramic capacitor is recommended between VCC and GND, placed as close as possible to pins 2 and 1 respectively. This minimizes high-frequency impedance and enhances immunity to VCC transients, as confirmed in the Typical Application Circuit and Applications Information sections of the datasheet.
Does AP1701AWG-7 meet AEC-Q200 for automotive use?
No. AP1701AWG-7 is not AEC-Q200 qualified. While its operating junction temperature range (–40°C to +105°C) meets automotive ambient requirements, it lacks the stress testing, failure analysis, and qualification documentation mandated by AEC-Q200. For automotive applications, Diodes recommends AEC-Q200-qualified alternatives such as the APX809Q series.
