This greatly enhances system stability. 4.2 V and 8 V UVLO (Under Voltage Lock Out) options ensure instant MOSFET and GaN protection under abnormal conditions. Under such circumstances, this UVLO mechanism provides crucial independence from whether and when other supervisors circuitries detect abnormal conditions. The output is able to sink 8 A and source 4 A currents utilizing a true rail-to-rail stage. This ensures very low on- resistance of 0.85 up to the positive and 0.35 down to the negative rail respectively. Industry-leading reverse current robustness eliminates the need for Schottky diodes at the outputs and reduces the bill-of-material. The pinout of the 1EDN family is compatible with the industry standard. Three package variants, SOT23 6-pin, 5- pin and WSON 6-pin, allow optimization of PCB board space usage and thermal characteristics.
