LM5067: LM5067 can be used for side switch driver

Karthik karri

Part Number: LM5067

Hi TI team,

can i use LM5067 in the low side switch application with operating voltage of 48V positive supply to the driver as shown in picture below:

Because in the LM5067 datasheet it is mentioned as -9 to -80V negative voltage supply .So LM5067 is applicable only for negative supply voltage or can i use it for positive supply voltage also ????

Hi TI team,

There is another question not relevant to LM5067 but i don't want to create new thread for it so asking in this thread only.

I have an application that requires current sensing and overcurrent protection. Therefore, I need an integrated circuit (IC) that combines both an amplifier for current sensing and a comparator for overcurrent protection.

Due to space constraints, I cannot use separate ICs for these functions.Do we have IC in TI that combines amplifer and comparator in one package??

The IC should operate with a 3.3V input and output rail-to-rail. Additionally, it must be automotive qualified to meet the application requirements.

Otherwise, please suggest a dual-channel opamp that would be suitable for this application.
