Hi Team,

We’re looking for an automotive high-side switch with the below features.

1. VSS- 18V, Load current- 2A, PWM- 5KHz, No of channels- 2

Then we’re unable to get PWM support for devices. Please help us to get the device that’s available with a maximum PWM frequency.

Thank You

    Hello, This series of products are designed for the one-time switch, so it is used for low frequency, if PWM is applied, we would recommend using lower than 300Hz, or for parts even <100Hz, you may relate to the ton/toff time of the part for details. Thank You

    Hello@vikas, It's always recommended to use a bleeder of 100 ohms. Vout of the part has an offset of around 250mV due to a leakage in no-load condition. The 100-ohm bleeder will pull it down. If there's no issue with 250mV offset the part can be used without bleeder also. If there's a concern with eRead more

    Hellovikas Nagpal,

    It’s always recommended to use a bleeder of 100 ohms.

    Vout of the part has an offset of around 250mV due to a leakage in no-load condition.

    The 100-ohm bleeder will pull it down.

    If there’s no issue with 250mV offset the part can be used without bleeder also.

    If there’s a concern with effectiveness while using a 100-ohm bleeder also a 500-ohm bleeder can be used. 500-ohm bleeder will have an offset of 65mV.

    Regards,

    Ashish Gawade

    Yes, Diodes manufactures its binary transistor products using separate die which are wire clicked to the lead frames. They aren't monolithic devices.
