Power management integrated circuit (PMIC) fused with Microcontroller (MCU) are very popular in modern electronic circuits. The variou PMIC devices comprise of the digital system and power subsystems with features such as Buck/Boost Converter, LED and display driver, temperature and pressure sensors, motion sensors, Fuel Gauge, etc… Supervisors are an important subset of PMIC and are used to detect system conditions such as overvoltage, current, temperature, etc and to protect the system from any fault conditions. LT2960HDC-3#TRPBF is one such supervisor which offers a wide range of features such as high-current overload protection, power and temperature monitoring, programmable threshold level, adjustable trip current level and short- circuit protection.

The LT2960HDC-3#TRPBF supervisor is mainly used for overvoltage and overcurrent protection. It is designed to protect circuits from high current surges or overvoltage and monitor their current and temperature level. It consists of a comparator and latch circuit, and an IEEE1149.1 compatible Programmable Logic Array (PLA) that helps in providing accurate and fast protection. The comparator compares the output of the power monitoring and protection circuit to an adjustable threshold voltage and generates an interrupt signal or trip signal when the voltage exceeds the predetermined threshold.

The LT2960HDC-3#TRPBF supports a wide range of input and output voltages, ranging from 1.5V to 5.5V. It features a programmable power trip point and a programmable temperature trip point, which can be programmed over the entire range of input and output voltages. It also features high temperature trip point detection and low temperature trip point detection. Additionally, the supervisor has an active noise filter that prevents false triggering due to noise in the input voltage. The supervisor also features a unique reverse diode blocking circuit, which helps protect the system from reverse voltage flow.

In addition, the supervisor supports a wide range of current levels, from 12A to 30A. A programmable current limit setting sets the upper bound of current a system is allowed to draw, protecting it from electrical overload or a faulty connection. The supervisor can also detect fault conditions such as a short circuit in the system and automatically shut off the circuit.

The LT2960HDC-3#TRPBF supervisor is suitable for applications such as consumer electronics, automotive, industrial and medical devices and systems as well as computer motherboards. It can also be used in applications where overvoltage or overcurrent protection is required. The supervisor is also ideal for applications where a number of systems need to be monitored and protected, as it offers a wide range of features such as high-current overload protection, programmable threshold settings, adjustable trip current level and short-circuit protection.
