Product details
Overview
APX810S00-29SA-7 from Diodes Incorporated is a micro-power voltage detector IC designed for µP supervisory functions in 3.0V digital systems. It provides active-high push-pull RESET output with 2.93V threshold (typ.), 240ms reset timeout, 7µA supply current (typ.), and guaranteed operation down to VCC = 1.0V - deployed in battery-powered controllers and embedded instrumentation.
For engineers reviewing the APX810S00-29SA-7 datasheet, APX810S00-29SA-7 pinout, APX810S00-29SA-7 application, or APX810S00-29SA-7 equivalent, key selection criteria include reset threshold accuracy over temperature (±30 ppm/°C), low-voltage validity (1.0V), push-pull drive capability (500µA source / 1.2mA sink), and SOT23-3 footprint compatibility in space-constrained designs.
Technical Context
The APX810S00-29SA-7 integrates a precision bandgap reference and comparator to monitor VCC against a fixed 2.93V threshold. Its internal timing circuit ensures minimum 240ms RESET assertion after power-up or brownout recovery, independent of external components.
Designed for single-supply operation from 1.0V to 5.5V, it delivers rail-to-rail output logic states with push-pull drive - eliminating need for external pull-up resistors. The reset output remains valid and monotonic across full -40°C to +125°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.93V (typ.), ±0.04V tolerance - matches 3.0V system supply monitoring with margin |
| Reset Timeout | 240ms (min) - ensures reliable µP initialization after power stabilization |
| Supply Current | 7µA (typ.) - enables multi-year operation on coin-cell batteries |
| Operating Voltage Range | 1.0V to 5.5V - supports valid reset assertion during deep brownout |
| Output Type | Push-pull active-high - drives logic inputs directly without pull-up resistor |
| Temp Coefficient | 30 ppm/°C - maintains threshold stability across industrial temperature range |
| Reset Propagation Delay | 20µs (max) - responds rapidly to VCC dips below threshold |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809SEUR+T | 2.93V threshold, 140ms reset timeout, open-drain output requiring external pull-up | Lacks push-pull drive; adds BOM cost and board area for resistor | Choose only if legacy MAX809 footprint reuse is mandatory and 140ms timeout suffices |
| TPS3808G18DBVR | 1.8V threshold (fixed), adjustable timeout (200ms–10s), higher 12µA ICC, SOT23-6 package | Requires re-layout due to 6-pin footprint and different threshold - not drop-in | Select when programmable timeout or tighter 0.5% threshold accuracy is required, accepting larger footprint |
Compared with MAX809SEUR+T and TPS3808G18DBVR, APX810S00-29SA-7 delivers true pin-compatible replacement for 3.0V systems needing 240ms reset hold time, zero external components, and lowest quiescent current in SOT23-3 - reducing total solution size and power overhead.

FAQ
What is the exact reset threshold voltage and its tolerance for APX810S00-29SA-7?
The APX810S00-29SA-7 has a nominal reset threshold of 2.93V at +25°C, with a guaranteed range of 2.89V to 2.97V across temperature and process variation. This 40mV window ensures robust detection of 3.0V rail collapse while avoiding false triggers from ripple or noise.
Does APX810S00-29SA-7 require an external pull-up resistor on the RESET pin?
No. APX810S00-29SA-7 features a push-pull output stage that actively drives HIGH (to VCC) and LOW (to GND), eliminating the need for an external pull-up resistor. This reduces BOM count, saves PCB area, and improves noise immunity compared to open-drain alternatives.
Can APX810S00-29SA-7 operate reliably at VCC = 1.2V?
Yes. The device guarantees correct RESET logic state and valid threshold comparison down to VCC = 1.0V, confirmed across -40°C to +125°C. At 1.2V, it asserts RESET if VCC falls below 2.93V (which it inherently does), and maintains defined output behavior throughout brownout recovery.
What is the maximum sink/source current capability of the RESET output?
The RESET pin can sink up to 1.2mA at VOL ≤ 0.3V (VCC = VTH + 0.2V) and source up to 500µA at VOH ≥ 0.8×VCC (VCC > VTH + 0.2V). These values ensure direct interfacing with standard CMOS inputs without level-shifting or buffering.
