The LTC2939HMS#TRPBF is a power management integrated circuit (PMIC) that offers excellent power supply control, monitoring, and diagnostics, ideal for a wide range of applications. The device is designed to simplify design, reduce costs, and enhance the reliability of devices powered by single or multiple supplies from 6V to 24V, or from high-voltage ac power sources. The LTC2939HMS has many features such as up to four configurable high-precision current and voltage monitors, a configurable gain instrumentation amplifier, and many more.

The LTC2939HMS is part of Linear Technology’s broad portfolio of power management ICs and is suitable for reliable operation in a wide range of applications. It is available in a 9- to 16-pin surface-mount package and is provided as standard microcontroller (MCU) and peripheral enabled parts with integrated signal conditioning and onboard regulators. The device can be used with either single or multiple supplies and has current limit outputs for controlling up to four voltage and current supplies up to 24V. The device has configurable voltage and current monitoring, and can provide margin, on-off, and control signals for the supply and supplies. The device also features an on-board Gain Instrumentation amplifier with adjustable gains that provide +/-10V, +/-5V, and +/-1V outputs from test points.

The LTC2939HMS’s automatic diagnostic and reporting functions help reduce system complexity and provide a reliable failure-response. The integrated diagnostics can monitor and report on power supply conditions, such as short and open circuit, over-voltage, under-voltage, over-current, and over-temperature. The diagnostics can be set to trigger an output signal if any of these conditions occur. The device also has built-in protection functions such as active current limiting, over-temperature shutdown, short-circuit monitoring, and over-voltage protection..

The LTC2939HMS is designed for use in computing and embedded applications. It is ideal for high-speed mixed-signal designs that may require reliable power and temperature monitoring and control, as well as integrated sense and drive of peripheral devices such as LED or LCD backlighting or LED/LCD display dimming. It can also be used to efficiently transfer power from a fixed output supply to multiple outputs.

In summary, the LTC2939HMS is an excellent choice for power supply control, monitoring, and diagnostic applications in industrial, automotive, and medical electronics. Its robust set of features and functionalities, combined with its integrated signal conditioning and onboard regulators, make it an ideal solution for enabling reliable, efficient, and robust power management in high-end embedded systems.
