MAX804SCSA+ Application Field and Working Principle
The MAX804SCSA+ is a multi-functional PMIC-Supervisors IC designed with adjustable undervoltage (UV) and overvoltage (OV) thresholds. It provides system designers the essential monitoring, protection and reset functions, allowing the designer to create safe and reliable circuits with minimal components. Given the wide range of functions, the MAX804SCSA+ can be used in a variety of circuits, including battery-powered systems, embedded systems, data acquisition equipment and process control.
Overview
The MAX804SCSA+ is a versatile supervisor IC that offers wide range of features for protecting a range of equipments from failures due to power spikes or voltage fluctuations. It also offers overvoltage (OV) and undervoltage (UV) detection and reset functions, brown out reset (BOR), watchdog timer, and external interrupt functions. Using these features, the MAX804SCSA+ can protect systems from over-temperature, over-voltage, under-voltage and over-current events.
Application Field
The MAX804SCSA+ can be used in a wide range of applications, including:
- Battery-powered systems
- Embedded systems
- Data acquisition systems
- Process control systems
The MAX804SCSA+ is ideal for use in the automotive or industrial fields. The precision voltage monitoring and events can be combined with on-board watchdog timer for reliable and safe system operation, such as controlling power and operation of vehicles or ignition control.
Working Principle
The MAX804SCSA+ continuously monitors the input voltage and detects any over-voltage or under-voltage events. When it senses an over-voltage or under-voltage event, it will trip the UVLO or OVLO pins, depending on the event, to signal a reset. The MAX804SCSA+ also has a built-in timer, which can be programmed to issue periodic reset if the monitored voltage falls below a preset level. Additionally, the MAX804SCSA+ has a brown-out reset (BOR) and an external interrupt that can be programmed to issue a reset upon receipt of input signals.
The MAX804SCSA+ can be configured to drive an I/O pin upon detection of a reset condition. The I/O pin can be used to drive an external circuit or to send system reset signals. The I/O pin is active low, so the driving capability of the MAX804SCSA+ is limited to the low side of the circuit.
The MAX804SCSA+ also provides advanced features, including temperature monitoring. Using an external NTC thermistor, the MAX804SCSA+ is capable of detecting high temperature events and issuing a reset accordingly.
The MAX804SCSA+ can also monitor other system parameters, such as current or a logic input. Using its adjustable voltage threshold, it can detect abnormal levels of current or logic inputs and issue a reset. This feature is useful for monitoring electrically noisy environments and providing system protection.
Conclusion
The MAX804SCSA+ is a versatile PMIC-Supervisors IC that offers wide range of features for protecting a range of equipments from failures due to power spikes, voltage fluctuations, temperature and current faults. Its wide range of application fields and precision voltage monitoring and reset options make the MAX804SCSA+ an ideal choice for reliable, safe operation in a variety of systems.
