PMIC, or Power Management Integrated Circuit, is the cornerstone of powering a wide variety of electronic devices. It coordinates energy management activities such as voltage regulation, power sequencing, load-sharing, current and voltage monitoring, over-current and over-temperature protection, and so on. PMICs have a wide range of applications from very small embedded devices to high-performance computers in a variety of industries such as automotive, consumer, professional audio and industrial.

The LTC2935CDC-3#TRPBF is a low-cost supervisory circuit specifically designed to monitor system power-on and reset functionality. This PMIC consists of a battery-backed temperature monitoring circuit, backup supply regulator, and a microprocessor-based independent system supervisor. It is able to detect power-on and reset signals from both a V DD supply and an external source, as well as monitor multiple battery supply voltages and other critical power supplies.

The LTC2935CDC-3#TRPBF supervisors are designed to detect system power-on and reset, providing users with a robust, easy-to-implement solution. It is capable of monitoring two DC input supplies, a microprocessor minimal voltage (MV) supply and an auxiliary supply. The device also offers multiple reset functions such as lasting power-on reset (POR), tamper reset (TR), hardware reset (HWR), microprocessor reset (MPR) and more.

In addition to detecting system power-on and reset, the LTC2935CDC-3#TRPBF can also monitor battery supply voltages and temperatures. The device has two temperature sensing ports with an input voltage range from -40°C to +125°C. It also features a wide operating temperature range from -55°C to +125°C, allowing for designs in a wide variety of environmental conditions. The device includes a low quiescent current backup regulator and an internal power-on reset generator, enabling fast power-up of the system.

The device can be configured to generate system reset or system power-on reset signals in response to DC voltage or temperature conditions. It can also detect reset signals from an external source and multiple voltage supplies, providing a versatile reset solution. The device provides failsafe auto recovery reset function when the system is powered-up, protecting the system from potentially damaging power surges.

The LTC2935CDC-3#TRPBF can be used in a broad range of applications including automotive, health care, industrial, consumer, and professional audio. Its feature-rich set of sensing and reset functions, wide operating temperature range, low power consumption and cost make it a popular choice for a variety of applications. Its easy-to-use system supervisor functions simplify power-up and reset tasks, making it ideal for system designers looking for an efficient and cost-effective solution for their power management needs.
