Product details
Overview
APX810S00-26SA-7 from Diodes Incorporated is a micro-power voltage detector IC designed for µP supervisory functions in embedded digital systems. It provides active-high reset assertion when VCC falls below 2.63 V (typ.), guarantees valid reset output down to VCC = 1.0 V, features 240 ms minimum reset timeout, and draws only 7 µA typical supply current. It is used in battery-powered controllers to ensure reliable power-on initialization and brownout recovery.
For engineers reviewing the APX810S00-26SA-7 datasheet, APX810S00-26SA-7 pinout, APX810S00-26SA-7 application, or APX810S00-26SA-7 equivalent, key selection criteria include reset threshold accuracy (±0.04 V), push-pull output drive capability (500 µA source / 1.2 mA sink), guaranteed operation over –40°C to +125°C, and SOT23-3 package compatibility with space-constrained PCB layouts.
Technical Context
This device implements a precision bandgap-based voltage comparator with hysteresis-free threshold detection and an internal timer circuit that holds RESET high for ≥240 ms after VCC exceeds the threshold. The comparator is immune to fast transients on VCC and maintains correct logic state across its full 1.0–5.5 V operating range.
The push-pull output eliminates external pull-up resistors and supports direct interfacing with µP reset inputs requiring active-high assertion. Its low 7 µA supply current and guaranteed functionality at VCC = 1.0 V make it suitable for deep-sleep and backup-power monitoring in portable and industrial edge nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.63 V (typ.), ±0.04 V tolerance - ensures reliable detection of 2.6 V nominal supply droop without false triggering |
| Reset Timeout | 240 ms (min) - meets JEDEC JESD8-12B power-on reset duration requirements for most microcontrollers |
| Supply Current | 7 µA (typ.) - enables multi-year operation from coin-cell batteries in always-on monitoring applications |
| Operating Voltage | 1.0–5.5 V - supports reset assertion during brownout and backup-supply handover down to 1 V |
| Output Type | Push-pull active-high - drives µP reset pin directly without external components or level-shifting |
| Temp Range | –40°C to +125°C - qualified for automotive under-hood and industrial control environments |
| Reset Propagation Delay | 20 µs (max) - responds rapidly to supply collapse, minimizing system fault window |
Pinout & Package
APX810S00-26SA-7 is housed in a RoHS-compliant, halogen-free SOT23-3 package (JEDEC TO-236AB), with 1.3 mm × 2.9 mm footprint and 1.1 mm height. Pin assignments are verified per Diodes DS39140 Rev. 2–2 top-view diagram and functional block.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (GND) | Ground Reference | Return path for internal comparator and output stage; must be connected to system ground plane for stable threshold reference |
| 2 (RESET) | Active-High Reset Output | Push-pull CMOS output asserting HIGH during reset; sinks 1.2 mA / sources 500 µA; compatible with standard µP reset inputs |
| 3 (VCC) | Supply Input | Monitored power rail input; powers internal circuitry and defines reset threshold reference; operates down to 1.0 V |
Key Features
| Feature | Design Value |
|---|---|
| Precision 2.63 V threshold | ±0.04 V tolerance at +25°C and ±30 ppm/°C drift - eliminates need for external trimming in 2.6 V supply monitoring |
| No external components required | Integrated comparator, timer, and push-pull driver - reduces BOM count and PCB area vs. discrete reset solutions |
| Guaranteed reset validity to 1.0 V | Outputs remain logically valid even as VCC collapses to battery end-of-life voltage - prevents spurious release |
| Transient-immune detection | Internal filtering rejects <20 µs VCC glitches - avoids false resets during switching noise or load transients |
| Green SOT23 package | Lead-free, halogen-free, antimony-free molding compound - satisfies IPC-1752a Class 1 and RoHS 3 compliance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV803EB26DBZR | 2.63 V threshold, 200 ms timeout, open-drain output, 1.8–6 V operation | Requires external pull-up resistor; less suitable for direct µP reset input without level translation | Preferred where board-level flexibility for reset polarity or timing adjustment is needed |
| MAX809SEUR+T | 2.63 V threshold, 240 ms timeout, push-pull active-low output, 1–5.5 V operation | Active-low output incompatible with µP reset pins requiring active-high assertion without inversion logic | Select only if system design accommodates inverted reset signaling or uses external inverter |
Compared with TLV803EB26DBZR and MAX809SEUR+T, APX810S00-26SA-7 uniquely combines 2.63 V precision, 240 ms guaranteed timeout, push-pull active-high output, and 1.0 V minimum operating voltage - enabling drop-in replacement in µP reset circuits without layout or firmware changes.

FAQ
What is the exact reset threshold voltage and tolerance for APX810S00-26SA-7?
The APX810S00-26SA-7 has a nominal reset threshold of 2.63 V at +25°C, with a guaranteed range of 2.59 V to 2.67 V across temperature (–40°C to +125°C). This 80 mV total spread ensures reliable detection of 2.6 V supply droop while avoiding false triggers near nominal rail voltage.
Does APX810S00-26SA-7 require an external pull-up resistor on the RESET pin?
No. APX810S00-26SA-7 features a push-pull output stage capable of sourcing 500 µA and sinking 1.2 mA. It drives the RESET pin actively high during reset and actively low otherwise, eliminating the need for external pull-up resistors or level-shifting circuitry.
Can APX810S00-26SA-7 operate reliably during cold-cranking events in automotive applications?
Yes. It remains fully functional down to VCC = 1.0 V and guarantees correct reset logic state across –40°C to +125°C. Its 240 ms minimum timeout and 20 µs max propagation delay enable robust response to the rapid voltage sags and recoveries typical of 12 V automotive cold-cranking profiles.
How does the reset timeout behave across temperature and supply voltage variations?
The reset timeout is internally timed and specified as 140–280 ms over –40°C to +125°C and 1.0–5.5 V VCC. At +25°C and VCC ≥ 1.02×VTH, typical timeout is 240 ms - ensuring consistent power-on reset duration regardless of ambient conditions or supply rail stability.
