Description
The control and enable inputs are LV-TTL compatible (CMOS 3.3 V) with an input voltage range from -5 V to +20 V.
-10 V input pin robustness protects the driver against latch-up or electrical overstress which can be induced by
parasitic ground inductances. 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
Ω
up to the positive and 0.35
Ω
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.
