Linear Technology LTC2938CMS#PBF Power Supply Monitor

The LTC2938CMS#PBF is a highly integrated power supply monitor and sequencer, designed and manufactured by Linear Technology, a leader in the design and production of high-performance analog integrated circuits. This advanced component is engineered to monitor up to four power supply voltages simultaneously, ensuring that complex systems with multiple power rails operate reliably and within their specified voltage ranges.

Key Features

• Voltage Monitoring: The LTC2938CMS#PBF can monitor four voltages that are critical to the system's performance. This feature is essential for systems that require precise voltage levels for optimal operation.
• Programmable Sequence: Users can program the sequence in which the power supplies are enabled or disabled, allowing for a controlled power-up and power-down sequence to prevent damage to sensitive components.
• Adjustable Reset Timer: The device includes an adjustable reset timeout that provides flexibility in determining how long the system should attempt to correct an out-of-spec condition before a reset is triggered.
• Flexible Configuration: Configuration is made easy through the use of external resistors or a serial interface, which allows for precise settings tailored to specific system requirements.
• Cascade Capability: For systems with more than four power rails, multiple LTC2938 devices can be cascaded, thus expanding the monitoring and sequencing capabilities without significant complexity.

Applications

The LTC2938CMS#PBF is ideal for a wide range of applications, including:

• Telecommunications
• Servers and Networking Equipment
• Industrial Systems
• Medical Equipment
• Automotive Electronics

Reliability and Packaging

The device is housed in a compact MSOP-16 package, which offers a space-saving solution and is suitable for high-density circuit boards. The LTC2938CMS#PBF is also characterized for operation over the industrial temperature range, ensuring reliable performance under varying environmental conditions.

With its robust feature set and Linear Technology's reputation for quality, the LTC2938CMS#PBF is an excellent choice for designers looking to enhance the reliability and functionality of their power management systems.
