DS1834AS/T&R

PMIC supervisors are critical components for many electronic systems. They are designed to protect the system against various overvoltage and undershoot conditions, ensuring the system remains in a safe operating state. The DS1834AS/T&R is an example of a PMIC supervisor with various application fields and working principles.

The DS1834AS/T&R is a dual-channel supervisor designed to protect digital systems from power-related damages. This supervisor is designed to detect both positive and negative voltage spikes, as well as overcurrent conditions. The device can then respond to the detected condition by providing an adjustable reset pulse. Additionally, this supervisor provides user-selectable reset timing, making it ideal for a wide range of applications.

One of the biggest advantages of the DS1834AS/T&R is its low power consumption. This supervisor draws very little power from the system, making it suitable for battery-powered applications. The low power consumption also contributes to the low-power standby mode, ensuring that the supervisor will not drain the battery when the system is powered down.

The DS1834AS/T&R has a wide range of application fields. It is commonly used in digital systems such as appliances, consumer electronics, gaming products and various industrial products. It is also used in automotive systems to provide overvoltage protection and improved system safety. Additionally, this supervisor is commonly used in medical systems such as blood pressure and glucose monitors, where robust and reliable protection is required.

The DS1834AS/T&R works on the principle of looking for transient voltages that occur when the system is under stress. When the supervisor detects one of these voltages, it sends a reset signal to the system, effectively resetting the system and preventing damage. The reset signal can be programmed to be either active-low or active-high, depending on the system requirements. Additionally, the supervisor can be programmed to generate a reset pulse upon detection of a fixed voltage or an adjustable voltage.

The DS1834AS/T&R is a versatile and reliable PMIC supervisor. With its adjustable reset timing, low power consumption and wide range of application fields, it is an excellent choice for protecting digital systems from many power-related damages. With its robust design, the DS1834AS/T&R is sure to provide reliable protection for many years to come.
