BQ242323H - Resistor Iset in USB 100 MODE?

Alexandre Becker

Hello,

There is a need to have ISet resistor (pin 16 ) when the BQ24232H is configured for USB 100 MODE ( EN1 = EN2 = GND ) ?

No you can leave ISET float.

Thanks,

Thanks for the answer. But check in practice that need Riset . Without it the load current falls 3.6mA and with RISET (4.7KOhms) goes to 96mA current (measured) , then you have the resistor in USB100 MODE. I want to take this opportunity to praise the component in question , very good and greatly facilitates the design .
