LTC2925CGN#PBF

PMIC - Power Supply Controllers, Monitors

LTC2925CGN#PBF is a Power Management and System Monitor integrated circuit which combines a temperature sensing section, supply voltage monitoring and operating current monitoring. It’s a multi-function device which can be used for a wide range of applications, such as monitoring power supplies, protecting power supplies against over or under voltage conditions or ensuring proper operation of any electronic device or system.

Application Field

The LTC2925CGN#PBF is an ideal choice for applications where multiple voltages are monitored and controlled. It is ideal for monitoring and controlling of power supplies with multiple voltage rails, such as DC/DC converters, switch mode and linear regulators. It can also be used in systems that require multiple voltage rails, such as motor drives, small motor control systems and industrial equipment. Additionally, the LTC2925CGN#PBF can be used in systems that require power supply protection, such as battery management systems, and in systems that require voltage sequencing and monitoring of the power supplies.

Working Principle

The LTC2925CGN#PBF works by monitoring multiple currents and voltages in a power supply system. It has a fully-integrated precision bandgap voltage reference and programmable threshold detectors that detect when any of the monitored voltage or current levels are outside of acceptable parameters. If any of the monitored voltages or currents exceed the programmed thresholds, an interrupt is triggered and an output signal is sent out to indicate the power supply fault. The LTC2925CGN#PBF then shuts down the power supply, sending out an alarm signal to indicate that power has been lost. Additionally, the LTC2925CGN#PBF can be used to sequence the power supplies in a system and can monitor the operating power of devices.

The LTC2925CGN#PBF is an ideal choice for applications where multiple voltages need to be monitored and controlled. It is easy to use, provides accurate voltage and current monitoring, and is able to detect faults quickly and reliably. The wide supply voltage range and on-chip temperature sensor make it suitable for a variety of applications, including power supply protection and voltage sequencing. Additionally, the integrated bandgap voltage reference allows for precise and accurate voltage monitoring.
