The LTC2978ACUP#TRPBF is a high-precision digital power monitoring IC from Linear Technology. It is a member of the PMIC – Power Supply Controllers, Monitors family, which are designed to provide system monitoring, error detection, and control functions. It is a fully-featured power monitoring device, with an integrated analog front-end and a sophisticated digital signal processor with up to 16 programmable GPIOs. It enables multiple power supplies to be monitored independently, allowing flexible power supply configurations.

The LTC2978ACUP#TRPBF operates on a wide input supply range of 4.2V to 18V and is capable of monitoring both common-mode and differential voltage signals. It has an integrated analog front-end that includes dual 12-bit, 2Msps data converters, an amplifier, attenuator, analog multiplexer, comparator and GPIOs. In addition, it has an integrated voltage and temperature sensor for general-purpose and high-VIN monitoring applications. It uses Linear’s patented Digi-Power technology which minimizes the timestamp and noise synchronization error for accurate voltage and temperature readings.

The LTC2978ACUP#TRPBF has a wide range of real-time monitoring and control features including Power-Ok, Soft Start, Over Voltage, Under Voltage, Over Temp, Over Current, Brown Out and Power Down alarms. It is capable of providing an output signal when any of these conditions are met, allowing the user to quickly adjust the power supply settings and prevent any catastrophic failures. In addition, it has a high-current pulse-width modulator (PWM), which can be used to control the power supply’s output current.

The LTC2978ACUP#TRPBF primarily targets battery-power systems, and is suitable for the application fields ranging from portable consumer electronics and communication devices to industrial, automotive, and medical applications. It Ultra-low power consumption of 335μA typical enables long battery life, and the wide operating temperature range of -40°C to +125°C allows it to be used in extreme environments.

The LTC2978ACUP#TRPBF is a highly integrated power monitoring IC. It provides an accurate, real-time view into the inputs and outputs of an electronic system, and can be used to detect, log, and remediate power supply problems before they turn into system crashes or even fires. It is an ideal solution for anyone looking for a reliable, cost-effective way to monitor and control multiple power supplies.
