Product details
Overview
APX810S00-40SA-7 from Diodes Incorporated is a micro-power voltage detector IC designed for µP supervisory functions in digital systems powered by +4.0V supplies. It provides active-high push-pull RESET output with 1.7ms reset timeout, guaranteed valid operation down to VCC = 1.0V, and consumes only 7µA typical supply current. Used in portable equipment and embedded controllers requiring reliable power-on reset signaling.
For engineers reviewing the APX810S00-40SA-7 datasheet, APX810S00-40SA-7 pinout, APX810S00-40SA-7 application, or APX810S00-40SA-7 equivalent, key selection criteria include reset threshold accuracy (3.94–4.05V), temperature coefficient (30ppm/°C), low-voltage validity (to 1V), and SOT23-3 package compatibility with space-constrained PCB layouts.
Technical Context
The APX810S00-40SA-7 integrates a precision voltage reference and comparator to monitor VCC against a fixed 4.00V threshold (±1.5% at +25°C). Its internal timing circuit generates a 1.7ms minimum active-high RESET pulse after VCC rises above threshold, independent of external components.
Designed for robustness in noisy environments, it rejects fast transients on VCC and maintains correct logic state across -40°C to +125°C ambient range. The push-pull output drives loads directly without pull-up resistors, supporting sink/source currents up to 1.2mA at defined voltage conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.00V (typ), 3.94–4.05V (min/max) - sets precise power-fail detection point for +4.0V systems |
| Reset Timeout | 1.7ms (typ), 1–3.3ms (min/max) - ensures stable µP initialization after power rise |
| Supply Current | 7µA (typ), ≤16µA (max) - enables multi-year battery life in portable devices |
| VCC Validity Range | 1.0V to 5.5V - guarantees RESET logic integrity during brownout and startup |
| Output Type | Push-pull active-high - eliminates need for external pull-up, reduces BOM count |
| Temp Coefficient | 30ppm/°C - maintains threshold stability over industrial temperature range |
| ESD Rating | HBM ±6kV - protects against handling-induced electrostatic discharge |
Pinout & Package

| 1.7ms factory-trimmed timeout | Guaranteed minimum pulse width eliminates need for external RC timing network |
| 1V minimum VCC operation | Enables reliable reset assertion during deep brownout or ultra-low-power wake-up sequences |
| 7µA typical supply current | Reduces quiescent power draw in always-on monitoring circuits for battery longevity |
| SOT23-3 green package | Lead-free, halogen-free construction meets RoHS 3 and JEDEC MSL3 requirements |
Applications
| Industrial PLC Controllers | Portable Medical Monitors |
|---|---|
Use Scenario: Power sequencing and fault detection in programmable logic controller CPU modules operating from 4.0V rails.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809SEUR+T | 4.00V threshold, 240ms timeout, open-drain output, 1.2µA ICC | Requires external pull-up; longer timeout limits use in fast-boot systems | Select when ultra-low current dominates over timing precision and board space |
| TPS3808G01QDBVRQ1 | 4.0V threshold, adjustable timeout (1–10s), push-pull, 12µA ICC, AEC-Q100 qualified | Automotive-grade qualification; larger SOT23-6 footprint; higher cost | Select for automotive ECUs where qualification and extended timeout flexibility justify size/cost trade-off |
Compared with MAX809SEUR+T and TPS3808G01QDBVRQ1, the APX810S00-40SA-7 delivers optimal balance of compact SOT23-3 footprint, precise 1.7ms timing, and industry-standard 4.0V threshold-ideal for cost-sensitive industrial and portable designs where minimal BOM count and predictable startup behavior are critical.

FAQ
What is the exact reset threshold voltage for APX810S00-40SA-7?
The APX810S00-40SA-7 has a nominal reset threshold of 4.00V, with a guaranteed range of 3.94V to 4.05V at +25°C. This tolerance is maintained across the full industrial temperature range (-40°C to +125°C) with a maximum drift of ±30ppm/°C, ensuring stable detection of +4.0V supply faults in real-world conditions.
Does APX810S00-40SA-7 require an external pull-up resistor?
No. The APX810S00-40SA-7 features a push-pull output stage that actively drives both high and low states. Unlike open-drain supervisors, it does not require an external pull-up resistor-reducing component count, PCB area, and potential noise coupling from resistor parasitics.
Can APX810S00-40SA-7 operate below 1.8V supply?
Yes. The device is fully specified to operate with VCC as low as 1.0V. Its RESET output remains logically valid down to this level, enabling reliable supervision during deep brownout events or ultra-low-power wake-up sequences where other supervisors may fail or float.
Is APX810S00-40SA-7 compatible with lead-free reflow processes?
Yes. The APX810S00-40SA-7 uses a fully RoHS 3-compliant, halogen-free SOT23-3 package rated for standard lead-free reflow profiles (JEDEC J-STD-020, MSL3). Its maximum peak reflow temperature is 260°C, and it supports both no-clean and water-wash assembly processes.
