Diodes Incorporated APX810S00-46SA-7

Overview

APX810S00-46SA-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 drops below 4.63 V, maintains reset for ≥240 ms after recovery, operates down to 1 V supply, draws only 7 µA typical supply current, and uses a push-pull output in SOT23-3 (SA) package-ideal for battery-powered controllers and portable instrumentation.

For engineers reviewing the APX810S00-46SA-7 datasheet, APX810S00-46SA-7 pinout, APX810S00-46SA-7 application, or APX810S00-46SA-7 equivalent, key selection criteria include reset threshold accuracy (±0.06 V), guaranteed operation at VCC = 1 V, 240 ms timeout period, push-pull drive capability, and SOT23-3 footprint compatibility with space-constrained embedded designs.

Technical Context

The APX810S00-46SA-7 integrates a precision bandgap reference and comparator to monitor VCC against a fixed 4.63 V threshold with ±30 ppm/°C temperature coefficient. Its internal timing circuit ensures a minimum 240 ms reset pulse width after VCC exceeds the threshold, independent of external components.

Designed for low-voltage resilience, it guarantees valid logic-level RESET output across VCC = 1.0–5.5 V, with VOH ≥ 0.8×VCC at 500 µA source current and VOL ≤ 0.4 V at 3.2 mA sink current-enabling direct interfacing with 3.3 V and 5 V microcontrollers without level-shifting.

FAQ

What is the exact reset threshold voltage and its tolerance for APX810S00-46SA-7?

The APX810S00-46SA-7 has a typical reset threshold of 4.63 V, with a guaranteed range of 4.57 V to 4.69 V at +25 °C. Over the full −40 °C to +125 °C operating temperature range, the threshold drift is limited to ±30 ppm/°C, ensuring stable performance in industrial environments without recalibration.

Does APX810S00-46SA-7 require an external capacitor for reset timing?

No. The APX810S00-46SA-7 integrates all timing circuitry internally and delivers a guaranteed minimum reset pulse width of 240 ms after VCC rises above the threshold. No external capacitor or resistor is needed-reducing bill-of-materials cost and PCB footprint while improving reliability.

Can APX810S00-46SA-7 operate reliably at VCC = 1.2 V?

Yes. The device guarantees correct RESET logic state (low when VCC < 4.63 V, high when VCC ≥ 4.63 V) down to VCC = 1.0 V. At 1.2 V, the output remains functional with VOL ≤ 0.4 V and VOH ≥ 0.8×VCC, enabling safe µP shutdown before data corruption occurs during deep brownout.

Is the SOT23-3 (SA) package of APX810S00-46SA-7 lead-free and halogen-free?

Yes. The SA package uses Diodes Incorporated's "Green" molding compound: fully RoHS 3 compliant (2015/863/EU), lead-free, antimony-free, and halogen-free-with bromine and chlorine each < 900 ppm and total Br + Cl < 1500 ppm-meeting stringent environmental requirements for global electronics manufacturing.
