Power management integrated circuits (PMIC) are an essential component in the majority of modern electronic designs. They provide the necessary voltage, current, and monitoring abilities that enable a variety of systems to run optimally and safely. One popular PMIC device is the DS1705ESA/T&R, a highly-integrated and reliable supervisory circuit that provides protection and monitoring for a range of voltage supplies. This article will discuss the application field and the working principle of the DS1705ESA/T&R.

The DS1705ESA/T&R is a CMOS, low-power supervisor specifically designed for automotive and industrial/telecom applications such as lighting, tool control, and battery management. It is an all-in-one supervisor that offers fail-safe protection and monitoring for voltage levels, battery undervoltage, overvoltage, and reverse polarity. It also provides supervisory functions such as power-on reset (POR), power-down reset (PDR), windowed Watchdog, and watch-time window monitoring.

In terms of its application field, the DS1705ESA/T&R can be used to provide battery monitoring and protection in a wide range of applications, from automotive and telecom to industrial, consumer and medical. It can also be used to monitor and protect user settings such as memory, clocks, and switches. Additionally, it can be used effectively in power-up sequences, where the POR and reset timing features help to implement a well-timed start-up sequence.

In terms of its working principle, the DS1705ESA/T&R monitors the battery voltage, and compares it with the set thresholds, which can be programmed using the voltage selection pins. If the voltage falls outside of the specified thresholds, then the device will generate an active-low reset signal that can be used to reset circuitry. The time window for reset can also be adjusted using the time selection pins. Additionally, the DS1705ESA/T&R can be used to monitor inputs such as POR, PDR, and watchdog, and provide a reset signal when any of these inputs fall outside their specified ranges.

The DS1705ESA/T&R is a highly integrated, cost-effective and reliable supervisor. Its all-in-one design helps engineers minimize the need for additional components, and its easy-to-configure features make it an ideal solution for a wide range of voltage protection and monitoring applications.
