S-1003NA34I-I6T1U

Power management integrated circuit (PMIC) supervisors are miniaturized voltage monitor modules designed specifically for power management in modern semiconductor applications. The S-1003NA34I-I6T1U PMIC supervisor integrated circuit is one such example.

The S-1003NA34I-I6T1U is a next-generation Precision Microelectronic Voltage Supervisor with push-pull output that creates a regulated output voltage of 3V - 5.5V. It features an integrated power supply supervisor, an active current source for low-battery detection, a low-battery detect source, an adjustable reset threshold, a PowerON reset, an integrated watchdog timer, choke input protection, and a thermal shutdown detector.

Application Field

The S-1003NA34I-I6T1U is designed for use in a variety of electronics applications. These include computers, personal electronics, industrial electronics, instrumentation, medical applications, battery powered devices, automotive electronics, and power management.

The device is ideal for low-power mobile and embedded applications in which the power management design requires maximum flexibility, reliability, and accuracy. It can also be used to protect systems by monitoring system voltages and thresholds and issuing a reset if the threshold is exceeded.

Working Principle

The S-1003NA34I-I6T1U has an integrated power supply supervisor which monitors the input power supply and issues a reset signal if the supply voltage drops below the reset threshold value. This reset signal is routed to the system microcontroller, which can then take necessary actions to protect the system from further damage due to low power supply voltage.

The device also features an integrated low-battery detect source which monitors the and battery voltage and generates an alarm signal if the battery voltage drops below the detection threshold. This alarm can be used to alert the user or system administrator before the battery runs out of power.

The S-1003NA34I-I6T1U also features an adjustable reset threshold and a PowerON reset which ensures that the system is reset and initialized correctly after power is applied. It also features a choke input protection to ensure that the system operates correctly during power supply transients.

The S-1003NA34I-I6T1U also includes a thermal shutdown detector to protect the system from excessively high temperatures. If the temperature exceeds a certain threshold, the thermal shutdown detector triggers a reset signal to the system microcontroller, which can then take necessary steps to reduce heat.

The S-1003NA34I-I6T1U also has an integrated watchdog timer which generates a reset signal if the microprocessor fails to execute a program within a certain period of time. This ensures that the system remains safe and stable in the event of a software or hardware failure.

Conclusion

The S-1003NA34I-I6T1U is an advanced power management IC (PMIC) supervisor designed for a wide range of electronic applications that requires high flexibility, reliability, and accuracy in power management. The device integrates a power supply supervisor, a low-battery detector, adjustable reset thresholds, a PowerON reset, an integrated watchdog timer, choke input protection, and a thermal shutdown detector which ensures the system operates safely and reliably during power supply transients, low battery voltage, and high temperatures.
