Product details
Overview
APX810-23SRG-7 from Diodes Incorporated is a 3-pin SOT23 microprocessor supervisory IC with active-high push-pull RESET output, precision 2.25 V reset threshold (±0.05 V), guaranteed reset validity down to VCC = 1 V, and 200 ms typical reset timeout period. It monitors 3.3 V/3.0 V/2.5 V power rails in embedded controllers and portable µP systems.
For engineers reviewing the APX810-23SRG-7 datasheet, APX810-23SRG-7 pinout, APX810-23SRG-7 application, or APX810-23SRG-7 equivalent, key selection criteria include reset threshold accuracy, VCC operating range (1.1–5.5 V), low 30 µA supply current, push-pull drive capability, and SOT23 footprint compatibility for space-constrained designs.
Technical Context
The APX810-23SRG-7 implements a precision bandgap-based voltage comparator with internal hysteresis and a monostable delay circuit to generate a minimum 140 ms (typ. 200 ms) active-high RESET pulse after VCC rises above 2.25 V. Its push-pull output drives CMOS inputs directly without external pull-up resistors.
It operates across –40°C to +85°C ambient, maintains reset assertion during brownouts by resetting the internal timer on each VCC dip below threshold, and guarantees correct logic state for VCC ≥ 1 V - enabling reliable startup sequencing in battery-powered systems where supply ramps slowly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.25 V ±0.05 V at –40°C to +85°C - ensures deterministic reset assertion before 3.3 V/2.5 V rail collapse |
| Reset Timeout Period | 140–280 ms - holds RESET high long enough to satisfy µP power-on reset timing requirements |
| Supply Current | 30 µA typical - enables multi-year operation in coin-cell–powered IoT sensors |
| VCC Operating Range | 1.1 V to 5.5 V - supports wide-input LDOs and direct connection to Li-ion, 3.3 V, or 5 V rails |
| Output Type | Push-pull active-high - eliminates need for external pull-up resistor and reduces BOM count |
| Reset Validity | Guaranteed down to VCC = 1 V - ensures known state during deep brownout recovery |
| ESD Protection | 5 kV HBM - provides robust handling in manual assembly and field-replaceable modules |
Pinout & Package
SOT23-3 (SR package) - 2.9 mm × 1.3 mm × 1.0 mm body, gull-wing leads, RoHS-compliant "Green" molding compound (Br/Cl <900 ppm, Sb <1000 ppm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC) | Supply Input | Power rail input; must be decoupled locally with ≥100 nF ceramic capacitor |
| 2 (GND) | Ground Reference | Low-impedance return path for reset comparator and output driver; connects to system ground plane |
| 3 (RESET) | Active-High Reset Output | Push-pull CMOS output; sinks/source up to 1.2 mA; asserts high when VCC ≥ 2.25 V + hysteresis |
Key Features
| Feature | Design Value |
|---|---|
| Precision 2.25 V threshold | ±0.05 V tolerance over full temperature range - avoids marginal reset behavior near 3.3 V rail dropout |
| No external components required | Integrated comparator, reference, and delay - eliminates discrete R/C network and reduces PCB area by >2 mm² |
| Push-pull active-high output | Drives µP RESET pin directly - removes pull-up resistor, saves cost, and prevents floating state during power ramp |
| 200 ms typ. reset timeout | Meets JEDEC JESD8-12E and most ARM Cortex-M MCU reset hold-time requirements |
| 30 µA supply current | Enables use in always-on wake-up circuits without compromising battery life in portable devices |
Applications
| Industrial PLC Controllers | Portable Medical Sensors |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD2T1G | 2.93 V reset threshold, open-drain active-low output, 14 µA ICC | Requires external pull-up; suited for legacy µP with active-low reset input | Select only if redesigning for active-low interface and higher threshold margin against 3.3 V rail |
| TPS3808G12DBVR | 1.2 V threshold, adjustable via external resistor, 2.5 µA ICC, enable input | Supports ultra-low-voltage domains (e.g., 1.8 V core); adds complexity with external components | Prefer for new designs requiring sub-2 V monitoring or programmable delay, not drop-in replacement |
Compared with MAX809TRD2T1G and TPS3808G12DBVR, the APX810-23SRG-7 offers fixed 2.25 V threshold with push-pull active-high output - simplifying layout and eliminating pull-up dependency while targeting mid-range 3.0/3.3 V systems where precise low-threshold supervision is critical.

FAQ
What is the exact reset threshold voltage and tolerance for APX810-23SRG-7?
The APX810-23SRG-7 has a nominal reset threshold of 2.25 V, with a guaranteed range of 2.20 V to 2.30 V over –40°C to +85°C ambient temperature. This specification is measured under standard test conditions per DS31322 Rev. 5–3, and applies to both rising and falling VCC transitions with built-in hysteresis.
Does APX810-23SRG-7 require an external pull-up resistor on the RESET pin?
No. The APX810-23SRG-7 features a push-pull output stage that actively drives RESET high or low - no external pull-up resistor is needed. This reduces component count, eliminates leakage paths, and ensures defined logic states during power ramp and brownout conditions.
Can APX810-23SRG-7 operate reliably below 2.5 V supply voltage?
Yes. The device is fully specified from VCC = 1.1 V to 5.5 V, with guaranteed reset assertion and valid output logic down to VCC = 1 V. At VCC < 1 V, the output enters high-impedance state, but this occurs only when the system is non-operational - consistent with its intended use case.
Is APX810-23SRG-7 pin-compatible with APX809-23SRG-7?
Yes - both share identical SOT23-3 (SR) pinout: Pin 1 = VCC, Pin 2 = GND, Pin 3 = RESET. However, APX809-23SRG-7 delivers active-low RESET, while APX810-23SRG-7 delivers active-high RESET. Swapping requires verifying µP reset polarity and adjusting firmware or logic-level translation.
