DESCRIPTION
The current sense is internally thermally compensated for optimum precision. The output voltage is adjusted from 0.5 V to 2 V with ± 1% accuracy overtemperature variations. The PM8908 also provides external tracking support. The PM8908 provides positive and negative overcurrent protection as well as over/undervoltage and overtemperature protection.
