I need some clarifications regarding the IC from STMicroelectronics: VN9E30FTR – 6-channel high-side driver with 24-bit SPI interface for traffic signal controller applications.
In the datasheet, it is mentioned that the internally limited current is 35A for channels IOUT0, IOUT1, IOUT2, IOUT3, IOUT4, and IOUT5.
Could you please confirm:
- Whether this 35A limit is shared across all channels ?
- If possible, provide the maximum allowable current per channel in a tabular format for reference.
Additionally, please advise if there are any precautions we need to take when switching the load per channel.
The Lamp Driver IC which is being used in Traffic Signal Controller should be capable of driving a load current of at least 5A per channel when all channels are switched ON simultaneously:
- Channel 1 – 5A
- Channel 2 – 5A
- Channel 3 – 5A
- Channel 4 – 5A
- Channel 5 – 5A
- Channel 6 – 5A
Total Load: 5A × 6 channels = 30A (all channels ON simultaneously), or as per the maximum load specifications recommended for the VN9E30FTR from ST Microelectronics please clarify??
We request the following details:
- Test procedure and a valid test report for the above operating scenario.
- Availability status and details of Indian distributors for bulk ordering.
- End-of-Life (EOL) information for the VN9E30FTR Lamp Driver Power IC.
Kindly provide the above information at the earliest.
