Working Principles

APX810S00-40SR-7 operates by continuously monitoring the supply voltage. When the voltage falls below the specified threshold (4.0V), the device generates a reset signal. This signal remains active until the voltage rises above the threshold and the reset timeout period (140ms) elapses. This functionality ensures that microcontrollers and other digital systems are properly reset when the supply voltage drops to critical levels.

Detailed Application Field Plans

APX810S00-40SR-7 finds applications in various electronic devices and circuits where voltage monitoring and reset functionality are crucial. Some common application fields include:

1. Battery-powered devices: Ensures proper operation and prevents data loss by resetting the system when the battery voltage drops to a critical level.
2. Microcontroller-based systems: Provides reliable reset functionality to ensure correct initialization and prevent software glitches caused by voltage fluctuations.
3. Industrial control systems: Monitors power supply voltages to protect sensitive equipment from damage due to voltage drops or spikes.
4. Automotive electronics: Ensures stable operation of automotive systems by resetting them in case of voltage disturbances.

Detailed and Complete Alternative Models

Currently, there are limited alternative models available with similar specifications and features as APX810S00-40SR-7. However, some alternative models that can be considered are:

1. APX810-40SR-7: Similar to APX810S00-40SR-7 but with a higher reset threshold voltage of 4.5V.
2. APX810L-40SR-7: Low-power variant with a quiescent current of 1µA (typical).

These alternative models provide flexibility in choosing the appropriate reset threshold voltage or reducing power consumption, depending on specific application requirements.
