The LTC2914HDHC-2#PBF is a high side, tracking current limit and thermal shutdown integrated circuit (IC). It is part of a family of peripheral monitoring modules (PMMs) called PMIC - Supervisors. This device is capable of tracking current and temperature, limiting current drawn by onboard devices, and maintaining power integrity.

The LTC2914HDHC-2#PBF is most commonly used in portable electronics and medical devices. It offers a wide assortment of functions including current limiting, monitoring, fault detection, and thermal shutdown. It is a small, compact IC that is well suited for applications with space constraints.

The first application field of the LTC2914HDHC-2#PBF is current limiting. Its 2-step current limiting feature allows it to limit the current drawn by the device to two specific levels for still providing adequate power for operation. This feature is important for portable devices where the power supply must be limited to ensure the device does not exceed its rated current limit and damage the device. The LTC2914HDHC-2#PBF has two current limit settings, one for normal operation and one for overload protection. This allows for an additional layer of protection should the device exceed its specified current limit.

The device is also equipped with a thermal shutdown feature that is used to protect the device should it exceed a specified temperature threshold. The thermal shutdown monitors and limits the amount of heat generated by the IC. If the IC exceeds the temperature limit, the device will automatically shut off to prevent damage. This feature is important for ensuring the longevity of the device and protecting it from overheating.

The LTC2914HDHC-2#PBF is also capable of monitoring and detecting faults within the device. Fault detection is important, as it allows the device to identify and respond to any issues that may arise during operation. The LTC2914HDHC-2#PBF is equipped with a voltage detect function that monitors the voltage level of the device. The voltage detect feature is used to detect and diagnose under-voltage or over-voltage conditions. The device can also detect and respond to open or short circuit conditions.

In addition to current limit and protection features, the LTC2914HDHC-2#PBF also offers efficient power management features. The device is equipped with a reset enable circuit that allows for quick and efficient power up and down sequencing. This is important for devices that require fast and reliable startup. The LTC2914HDHC-2#PBF also contain switching mode power supplies and a switching mode clock that are used to reduce power consumption, allowing the device to operate more efficiently.

The LTC2914HDHC-2#PBF is an excellent choice for a variety of applications. It can be used in portable electronics and medical devices to provide current limit and thermal protection, while providing robust fault protection, power management, and efficient power supply switching. Its compact size makes it ideal for use in tight spaces, and its wide range of features make it an excellent choice for a variety of applications.
