The L6380/L6381 is a high-voltage device with a driving stage floating up to 600V.
L6380 can be used to drive N-channel power MOSFET and IGBT, in high-side and low-side configurations.
L6380 has a logic input (CMOS and LSTTL compatible) and two comparator inputs compatible to ground.
To drive the external power device L6380 the signal coming from input logic is fed into a pulse generator that in turns drives the level shifting sructure (that include two High Voltage DMOS) designed to ensure low power dissipation and high noise immunity. The output buffer (in Totem Pole arrangement) is able to sink from or source to the gate of the external device the current needed to switch it ON or OFF.
The falling edge of the signal coming from the input logic will turn ON while the rising edge will turn OFF the driven power device. L6380 will ensure low current sinking from the HV rail during commutations.
