Product details
Overview
APX810S00-26SR-7 from Diodes Incorporated is a micro-power voltage detector IC designed for µP supervisory functions in digital systems. It provides active-high reset assertion when VCC falls below 2.63 V (typ), guarantees valid reset output down to VCC = 1 V, features 240 ms minimum reset timeout, consumes only 7 µA typical supply current, and is housed in a 3-pin SOT23-3 (SR) package-ideal for battery-powered controllers and portable instrumentation.
For engineers reviewing the APX810S00-26SR-7 datasheet, APX810S00-26SR-7 pinout, APX810S00-26SR-7 application, or APX810S00-26SR-7 equivalent, key selection criteria include reset threshold accuracy (±0.04 V), push-pull output drive capability (1.2 mA sink), guaranteed operation over –40°C to +125°C, and compatibility with 2.5 V/3.0 V/3.3 V/5.0 V supply rails.
Technical Context
The APX810S00-26SR-7 implements a precision bandgap-based voltage comparator with internal hysteresis to reject fast VCC transients. Its reset logic is latched and held until VCC exceeds the threshold by ≥2%, ensuring clean power-on sequencing in µP systems.
It operates across full industrial temperature range (–40°C to +125°C) with ±30 ppm/°C threshold drift and delivers a fixed 240 ms (min) reset pulse width after VCC recovery-no external timing components required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.63 V (typ), 2.59–2.67 V (min–max); ensures reliable detection of 2.6 V supply brownout |
| Reset Timeout | 240 ms (min); guarantees µP reset hold time sufficient for full system initialization |
| Supply Current | 7 µA (typ); enables multi-year battery life in always-on monitoring applications |
| Output Type | Push-pull active-high RESET; eliminates need for external pull-up resistor |
| VCC Validity Range | 1.0 V to 5.5 V; supports reset assertion even during deep brownout or partial power loss |
| Temperature Drift | ±30 ppm/°C; maintains <0.5% threshold error across full operating range |
| Output Drive | 1.2 mA sink at 0.3 V; directly interfaces with standard CMOS input thresholds |
Pinout & Package
APX810S00-26SR-7 is packaged in a RoHS-compliant, halogen-free SOT23-3 (SR variant) surface-mount package measuring 2.9 mm × 1.3 mm × 1.0 mm (L × W × H), with gull-wing leads optimized for automated assembly and thermal performance (θJA = 232°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for internal comparator and output stage; must be low-impedance connection |
| 2 | RESET | Active-high push-pull reset output; drives high to VCC when enabled, low during reset |
| 3 | VCC | Power supply input; powers internal circuitry and defines reset threshold reference |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD2T | 2.93 V threshold (fixed), 140 ms min reset timeout, 10 µA ICC | Suitable for 3.0 V systems but not 2.6 V rails; shorter timeout may cause premature µP release | Select only if 2.93 V threshold matches target supply and 140 ms timeout satisfies system boot timing |
| TPS3808G01DBVR | Adjustable threshold (0.4–5.0 V), 200 ms min timeout, 1.1 µA ICC, enable pin | Requires external resistor divider; ultra-low ICC benefits long-life IoT sensors but adds complexity | Prefer for flexible threshold design or sub-µA standby; avoid if fixed 2.6 V and minimal BOM are priorities |
Compared with MAX809TRD2T and TPS3808G01DBVR, the APX810S00-26SR-7 offers exact 2.6 V detection with industry-standard 240 ms timeout and zero external components-making it optimal for cost-sensitive, space-constrained 2.6 V supply monitoring where simplicity and reliability are critical.

FAQ
What is the function of Pin 2 on APX810S00-26SR-7?
Pin 2 is the RESET output terminal. It is an active-high push-pull driver that transitions to logic high (VCC) when VCC is above the 2.63 V threshold and pulls low (≤0.3 V at 1.2 mA) when VCC falls below the threshold. No external pull-up resistor is needed due to its integrated output stage.
Does APX810S00-26SR-7 require external capacitors for reset timing?
No. The device integrates all timing elements internally. Its 240 ms (minimum) reset timeout is factory-trimmed and requires no external capacitor or resistor-reducing bill-of-materials cost and PCB area while improving reliability versus RC-based solutions.
Can APX810S00-26SR-7 operate with a 1.8 V supply?
No. The device requires VCC ≥ 1.0 V to assert valid RESET, but its internal reference and comparator are optimized for nominal 2.5 V to 5.0 V supplies. At 1.8 V, the reset threshold is undefined and output behavior is not guaranteed per datasheet specifications.
How does the APX810S00-26SR-7 handle fast voltage transients on VCC?
The reset comparator incorporates built-in noise immunity circuitry that rejects transients ≤20 µs duration, as verified by tS parameter (20 µs max delay from VCC drop to reset assertion). This prevents false resets caused by switching noise or ESD-induced supply glitches.
