DS1238-10+

Power management integrated circuits (PMICs) are widely used in many types of electronic devices, such as cell phones, laptops, gaming consoles, and many other electrical appliances. They are designed to provide a reliable power supply for electronic devices, securing their operational reliability. PMICs are a combination of different parts of a power management solution, such as voltage regulators, power MOSFETs, referenced voltage sources, and supervisors.

Supervisors are one type of PMICs that are used to detect any abnormal situations in the system and act accordingly. Supervisors come in different packages, including the DS1238-10+ package. This supervisor offers a wide range of protection features, including undervoltage protection, over-voltage protection, high current protection, as well as temperature protection. It is designed for applications ranging from low powered consumer electronic devices to heavy duty industrial and automotive applications.

Application Field of the DS1238-10+ Supervisor

The DS1238-10+ supervisor is ideal for low power consumer applications due to its low power consumption. It is designed with a supply voltage range from 2.6V to 7.5V. This makes it suitable for a variety of applications such as gaming consoles, mobile phones, notebook PCs, personal digital assistants (PDAs), and even automotive applications. It also features short circuit protection and thermal shutdown protection, which make it ideal for applications in harsh environmental conditions.

The supervisor is also suitable for automotive applications due to its high current capability of up to 2.2A. It is also compliant to the AEC-Q100 standard, making it suitable for use in automotive products. It also features a wide range of safety features, including over-voltage protection, under-voltage protection, overcurrent protection, and temperature protection, making it ideal for automotive applications.

Working Principle of the DS1238-10+ Supervisor

The DS1238-10+ supervisor has a wide range of protection features, including undervoltage protection, over-voltage protection, and temperature protection. It also has an adjustable overvoltage threshold for improved protection. In addition to these, the supervisor also has an integrated Reset circuit that can detect abnormal conditions in the system, such as voltage trips and temperature trips. When triggered, the integrated Reset circuit will assert a Reset signal, which will turn off all power to the system and prevent the system from overloading and getting damaged.

The DS1238-10+ also features a temperature protection circuit, which is designed to detect temperature variations in the board and prevent over-temperature or under-temperature conditions. When the temperature of the board reaches a certain limit, the temperature protection circuit will send a signal to the integrated Reset circuit and deactivate the power supply. This ensures that your system remains safe from temperature related failures.

The supervisor is also designed with a power-off delay circuit. This circuit is designed to ensure that all devices on the board are properly turned off during a power cycle. This protects the devices from damage that could occur due to any sudden supply voltage changes and provides safety in case of power failure.

The DS1238-10+ supervisor also features a power-on reset circuit. This is designed to detect any power supply irregularities and reset the system accordingly. This is useful in preventing system failure due to incorrect power supply voltages or other power related problems.

Conclusion

The DS1238-10+ supervisor is a great choice for low power consumer applications as well as automotive applications. It provides a wide range of protection features, including undervoltage protection, over-voltage protection, high current protection, and temperature protection. It also has an integrated Reset circuit and power-on and power-off delay circuit for improved reliability. With its wide range of protection features and robust design the DS1238-10+ is an ideal choice for any application.
