PMIC - Power Supply Controllers, Monitors

The LTC1041CS8 is an 8-pin, serial voltage monitor based on a proprietary integrated circuit solution. It is designed to provide a precise, low-power solution for monitoring and controlling the input-voltage-discipline level of an analog signal chain. The LTC1041CS8 measures voltage signals across a low duty cycle, utilizing the smallest sample size of any converter available. The LTC1041CS8 is ideal for current monitoring, voltage control, or other precision analog signal-monitoring applications.

The LTC1041CS8 integrates a low-power sample-and-hold circuit, an 8-bit A/D converter and a serial interface with a single supply. The device operates from a 5V supply, and can sense an input voltage from 0V to the supply voltage. It is capable of monitoring input signals from voltages as low as 20mV, and from frequencies as low as 1kHz.

LTC1041CS8 Application Field

The LTC1041CS8 is well-suited for monitoring both dc- and ac-input voltage signals. It is particularly well-suited for input-voltage-discipline systems such as:

• Computer power supplies
• Motor control systems
• Industrial DC power systems
• Battery-powered systems
• Control systems and regulators
• High-dynamic-response systems

LTC1041CS8 Working Principle

The LTC1041CS8 combines a low-power sample-and-hold circuit, an 8-bit A/D converter and a serial interface with a single-supply operation from 5V. The device samples input signals of up to 7.5V and outputs the result in a serial format at clock rates up to 13kHz. The LTC1041CS8 uses a differential input configuration, which allows for increased accuracy and improved common-mode rejection. The device supports a programmable sample-and-hold time, and can store the analog signal for up to 11ms.

The LTC1041CS8 provides an 8-bit result which is output over a 3-wire serial interface. The 3-wire serial interface allows the device to be clocked at a higher speed, reducing power consumption further. The device consumes 390µA of power, and features a programmable reference voltage which sets the resolution of the conversion.

The LTC1041CS8 is specifically designed to provide accurate and reliable results in analog signal-monitoring applications. The device is able to measure temperatures, air flow, humidity, pressure, and other environmental factors with a high degree of accuracy. It can also be used to detect physical changes in an analog signal, such as a rise or fall in voltage. The device is also capable of accurately monitoring and controlling voltages in motor control systems, as well as in battery-powered systems.

The LTC1041CS8 is an excellent solution for input-voltage-discipline systems which need to monitor and control the input-voltage-discipline level of an analog signal chain. The device offers a precise and low-power solution for a variety of voltage-monitoring and control needs.
