SG Micro SGM48536

The SGM48536 is a single high-speed low- side gate driver for MOSFET and IGBT power switches. It can provide rail-to-rail driving capability and very small propagation delays (18.5ns, TYP). It also provide 4A peak source current and 8A peak sink current (asymmetrical drive) when V_DD = 12V. The input can withstand a maximum negative voltage of -10V.

The operating voltage range is 9V to 25V. The devices feature under-voltage lockout (UVLO) function. After UVLO is triggered, the output remains low.

The SGM48536 adopts separate output architecture. 

The SGM48536 is available in a Green SOT-23-6 package.
