ANALOG DEVICES MAX17614ATP+ Power Source Selector, 4.5 to 60 V, -40°C to 125°C, TQFN-EP-20

MAX17614ATP+ is an ideal diode/power source selector device. It offers adjustable protection boundaries for systems against positive and negative input faults upto +60V and -65V, and output load current upto 3A. This device features two internal nFETs connected in series with a low cumulative RON of 130mΩ (typ) and can be used to implement an ideal diode function to provide reverse input voltage and reverse current protection with improved system efficiency. Input undervoltage protection can be programmed between 4.5V and 59V, while the overvoltage protection can be independently programmed between 5.5V and 60V. Additionally, the device has an internal default UVLO rising threshold set at 4.2V (typ). It is used in applications like faster response times, tight current limit accuracy.
