The LTC2914HDHC-1#PBF is a component of the Power Management Integrated Circuit (PMIC) family. It is a supervising IC meant to guarantee safe system operation through the monitoring of power supply conditions.The LTC2914HDHC-1#PBF is built on two main features: the supervisor or monitor and the fault latch. The supervisor monitors voltage conditions (like an over-voltage or under-voltage detection) and then communicates its status through either a push/pull output signal or an open-drain output. The fault latch can be configured to stay on indefinitely if a fault condition is present or to stay on for a specified amount of time if a transient fault occurs.The LTC2914HDHC-1#PBF can be used in a number of applications including systems powered from batteries, automotive applications, etc. In these applications, the LTC2914HDHC-1#PBF can be used to guard against any critical fault condition that may arise and prevent damage to the system or its components.The Working PrincipleThe LTC2914HDHC-1#PBF is a monitor whose main purpose is to detect power supply conditions and to inform the user of the status of these conditions. It is configured to monitor either voltage levels (like an over-voltage or under-voltage detection) or current levels like over-current or peak current detection.When the conditions monitored by the LTC2914HDHC-1#PBF are outside of their given ranges, it will initiate a fault condition. This will cause the fault latch to be activated, and it will remain on until the fault condition is cleared. At the same time, its push/pull or open-drain output will indicate the fault condition status to its user.The LTC2914HDHC-1#PBF is capable of monitoring multiple voltages. It has two internally set thresholds for each voltage it monitors. These thresholds can be externally programmed by pulling the voltage input down to one of the activation levels and then releasing it. The activation levels can be adjusted to within 1% accuracy.ConclusionThe LTC2914HDHC-1#PBF is an integrated circuit (IC) meant to provide monitoring of power supply conditions. It can be used in battery operated systems, automotive applications, etc. to ensure that any faults are detected and safety is not compromised. Its supervisor and fault latch features work together to detect faults, report them and stay active until they are cleared. It also has two internally set thresholds that can be externally programmed with up to 1% accuracy.
