PMIC - Supervisors, one of the most essential tools for maintaining regular operations for many in-system applications, are the lifeline for a functional system. The LTC2914HGN-1#TRPBF from Linear Technology is a superior choice for precise power and thermal management, in combination with an array of features designed specifically with system-level performance in mind.

This product is a single-channel high/low temperature andvoltage supervisor with a temperature range from -45℃ to +185℃. The device itself is a small, low-cost package with an operating voltage of 2.25V to 5.5V and a high input-sensitivity threshold accuracy, totally reliable for its task at hand.

The main function of this PMIC is to guarantee safe operation by monitoring both temperatures and voltages. It is built with a 8-bit temperature register, span setpoints and hysteresis, as well as a comparator with a preset voltage monitor. The LTC2914HGN-1#TRPBF is also capable of setting initial thresholds in the span setpoint range.

Established systems such as drones and datacom equipment are just some of the application areas benefiting from the features and level of proficiency the LTC2914HGN-1#TRPBF can offer. Its response time is exemplary for a device of its kind and it is able to detect faults dynamically, before any serious damage can be done. The LTC2914HGN-1#TRPBF version comes with an open drain reset output and an active-low reset output.

The LTC2914HGN-1#TRPBF operates in five different modes, intended to control power supply and temperature in conjunction with a dedicated controller. The first one is the speed mode. This mode allows the supervisor to adjust the point of reference and immediately respond to any changes in temperature or voltage. The sequencer mode is responsible for sequencing and sequencing delay, activity and inactivity, as well as power-up sequencing. The secondsequencer mode is designed for re-sequencing in case of a fault.

The third mode is the watchdog mode. It is used to measure the time intervals between signals, responding further with automatic reset cycles or via an open-drain reset output. The fourth mode is the dual-timer mode, which has a shorter and a longer delay setting used for multiple purposes such as setting a dropout voltage or verifying supply voltage. Lastly, the lockout mode allows the supervisor to be disabled or enabled while preserving the current setpoints.

In conclusion, the LTC2914HGN-1#TRPBF is a perfect choice for reliable thermal and power management, no matter which area needs monitoring. With low power consumption and a high response time, this device is a great way to ensure maximum system performance and at the same time guarantee safety and security.
