Power management

Hello, I have L6472 with separate power for VSA/B and VDD+VREG (3V3). When VSA/B is powered off IC doesnt respon on SPI. What is propper procedure for power off communication?

In datasheet there is no any connection between VSA and/or VDD. In block schematic are these two voltages separated, also any mention about VSA voltage required to SPI function...

Hi, I want to know the exposed pad connection of LP825 IC. Is it connected to GND?

VNF1048 PWM output

Hello all,I'm currently building a power distribution module based on VNF1048F e-fuses. I want to limit the amount of power supplied to the receiver. I would like to do it with PWM output on VNF1048F, does anyone know how fast can the gate output be ...

I am looking a solution to design protection for 12 to 16 cell battery pack. I think the L9963E or L9961 maybe work. It is a requirement that no MCU should be used. Can the IC be program with settings by external device and runs by itself without MCU?

How does the quiescent current of STLQ020 change when operating in dropout?

Hi,I'm interested in the STLQ020 in a very low load current application and am keen to minimise quiescent current consumption.Looking at the data and graphs in the datasheet, I can see that the quiescent current use is maximum 1000nA at no load, and ...

Can I get simplis model for L5991 and L6565 ?
