The LTC2917HDDB-B1#TRPBF is a dual voltage supervisor device that is part of the PMIC (power management integrated circuit) supervisors. It offers complete protection for a variety of low voltage applications, including smart phones, tablets, portable wireless devices, and laptop and notebook computers. An onboard voltage regulator allows for a wide range of operating voltages; from less than 1.8V to as high as 5.5V (LTC2917HDDB-B1#TRPBF datasheet v2.2, 2017). This versatile voltage regulator allows the LTC2917HDDB-B1#TRPBF to be used in a number of different applications, from low-power embedded systems to high-performance, high-power systems.

The LTC2917HDDB-B1#TRPBF is a dual supervisor device that provides two channels of protection. It has two voltage detector pins – PP1 and PP2 – which can be used to set voltage thresholds for two different supply rails. If either of the supply rails falls outside of the specified thresholds, either an interrupt or reset signal will be generated (depending on the user’s configuration). The device also has one power on reset pin – POR – which will generate a reset signal when the supply voltage drops below 1.5V.

The LTC2917HDDB-B1#TRPBF is a very versatile device, as it can be used to monitor both low and high voltage supplies. For low voltage systems, the PP1 and PP2 voltages can be set at a maximum of 3.3V, while POR can be set to the lowest value of 1.5V. For high voltage systems, PP1 and PP2 can be set at a maximum of 5.5V, while POR can be set to the highest value of 4.2V. This allows the LTC2917HDDB-B1#TRPBF to provide reliable protection even in high-voltage, high-power systems. The device also provides a power-down feature; when the PP1 and PP2 pins detect a loss of voltage, they will automatically disable the POR pin, thus avoiding the need for an external power-down circuit.

The LTC2917HDDB-B1#TRPBF is designed to provide reliable, fast protection for low voltage circuits by monitoring the supply voltage. The two voltage detectors, PP1 and PP2, monitor the supply voltages and if either of the voltages falls outside of the specified thresholds, an interrupt or reset signal will be generated. This will shut down the system quickly and reliably in the event of a supply voltage fault. Additionally, the onboard power-down feature ensures that the POR pin will be disabled in the event of a PP1 or PP2 voltage fault, thus avoiding the need for an external power-down circuit.

In conclusion, the LTC2917HDDB-B1#TRPBF is a versatile, high-performance voltage supervisor device that is part of the PMIC (power management integrated circuit) supervisors. It is designed to provide reliable, fast protection in a wide range of low voltage applications, from basic embedded systems to high-performance, high-power systems. The two voltage detectors monitor the supply voltages and if either of the volts falls outside of the specified thresholds, an interrupt or reset signal will be generated. Additionally, the device also has an onboard power-down circuit to ensure that the POR pin is disabled in the event of a PP1 or PP2 voltage fault.
