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

Hii Team, Do Digital POL devices like TDA3860/ 740 devices work without a bleeder resistor on the output without affecting the operating system? Thank you for your help. Regards, Vikas

    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.

    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.

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