Product details
Overview
APX810S00-23SA-7 from Diodes Incorporated is a micro-power voltage detector IC designed for µP supervisory functions in 2.5V–5V digital systems. It provides active-high push-pull RESET output with 2.25V threshold, 240ms minimum reset timeout, 7µA typical supply current, and guaranteed operation down to VCC = 1.0V - used in portable equipment power monitoring.
For engineers reviewing the APX810S00-23SA-7 datasheet, APX810S00-23SA-7 pinout, APX810S00-23SA-7 application, or APX810S00-23SA-7 equivalent, key selection criteria include reset threshold accuracy (±0.03V), temperature coefficient (30ppm/°C), low-VCC validity (1.0V), push-pull drive capability (500µA source), and SOT23-3 footprint compatibility.
Technical Context
The APX810S00-23SA-7 implements a precision bandgap-based voltage comparator with hysteresis-free threshold detection at 2.25V nominal. Its internal timing circuit generates a fixed 240ms reset assertion window after VCC rises above threshold, independent of external components.
It features a push-pull output stage capable of sourcing 500µA at VCC ≥ VTH + 0.2V and sinking 1.2mA while maintaining VOL ≤ 0.3V. The device operates across –40°C to +125°C and remains functional down to VCC = 1.0V, ensuring robust brown-out detection during battery discharge.
Key Specifications

|---|---|
| Reset Threshold | 2.25V ±0.03V - precisely monitors 2.5V rail with margin for noise immunity |
| Reset Timeout | 240ms min - ensures full µP initialization before release |
| Supply Current | 7µA typ - enables multi-year battery life in portable devices |
| VCC Validity Range | 1.0V to 5.5V - supports deep brown-out detection and wide input range |
| Output Type | Active-high push-pull - eliminates need for external pull-up resistor |
| Temp Coefficient | 30ppm/°C - maintains threshold stability over industrial temperature range |
| Reset Propagation Delay | 20µs max - responds rapidly to supply dips without missing transients |
Pinout & Package
APX810S00-23SA-7 is housed in a RoHS-compliant, halogen-free SOT23-3 package (JEDEC TO-236AB), with 1.3mm × 2.4mm footprint and 0.95mm height - optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for internal comparator and output stage |
| 2 | RESET | Active-high push-pull reset output; drives µP /RESET pin directly |

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 | 2.5V threshold, 140ms reset timeout, open-drain output requiring pull-up | Lacks push-pull drive; adds external resistor and leakage path | Choose if 2.5V threshold matches system rail and board space allows pull-up |
| TPS3808G01DBVR | Adjustable threshold (via resistor divider), 200ms timeout, higher 12µA ICC | Requires two external resistors; less precise than factory-trimmed 2.25V | Prefer when flexible threshold tuning is needed and 5µA extra current is acceptable |
Compared with MAX809SEUR+T and TPS3808G01DBVR, the APX810S00-23SA-7 offers tighter 2.25V threshold accuracy, lower 7µA supply current, integrated push-pull output eliminating external components, and guaranteed 1.0V operation - making it optimal for space-constrained, battery-sensitive 2.5V systems.

FAQ
What is the exact reset threshold voltage of APX810S00-23SA-7?
The APX810S00-23SA-7 has a factory-trimmed reset threshold of 2.25V, with guaranteed limits of 2.22V (min) and 2.29V (max) at +25°C. This value is specified in the Electrical Characteristics table of DS39140 Rev. 2–2, and exhibits a temperature coefficient of 30ppm/°C across –40°C to +125°C.
Does APX810S00-23SA-7 require an external pull-up resistor?
No. The APX810S00-23SA-7 features a push-pull output stage that actively drives HIGH (up to VCC) and LOW (≤0.3V at 1.2mA sink), eliminating the need for an external pull-up resistor. This reduces component count, PCB area, and standby current compared to open-drain alternatives.
Can APX810S00-23SA-7 operate reliably below 2.5V supply?
Yes. The device is fully specified down to VCC = 1.0V, with guaranteed RESET output validity and correct logic state assertion throughout this range. This enables robust brown-out detection during battery discharge or LDO dropout scenarios where supply falls below nominal 2.5V.
What is the reset timeout duration and is it adjustable?
The APX810S00-23SA-7 provides a fixed 240ms minimum reset timeout period after VCC rises above the threshold. This timing is internally generated and not adjustable via external components - ensuring consistent, repeatable reset behavior without calibration or layout sensitivity.
