TPS650362-Q1: TPS650362-Q1: Technical query and reference design requirement.

Venkatachalam K

Part Number: TPS650362-Q1

Tool/software:

Hi Team,

1. Please share the reference design file for the TPS650362-Q1, as detailed schematic design guidelines are not available in the datasheet.

2. What is the transient duration of 35V?

3. Can we use the TPS650362-Q1 IC to withstand a 36V load dump?

We need your quick response to move forward.

Hello,

Do you have access to the full datasheet available inside of TI's mySecure Folder? If not, please request the full datasheet for the TPS65036x devices using the below link. Inside of the datasheet will be detailed schematic design guidelines.

Hi Jude Stehling

1. I have submitted a request for the folder access you recommended. Once I obtain access, I will review the schematic guidelines and transient duration.
2. I have an additional question: our device does not support I2C communication. In this scenario, can we utilize the pre-programmable TPS650362-Q1 IC? What are the alternatives for operating the PMIC in this case? We require a component that can handle the following voltage rails:
- 3.3V / 140mA
- 2.8V / 40mA
- 1.8V / 80mA
- 1.2V / 250mA

Hello,

It is possible to use the TPS650362-Q1 without I2C communication. The TPS65036x devices are One-Time Programmable (OTP), meaning that the configuration of many of the default registers controlling the device's behavior to certain conditions can be programmed one time. Then, these default registers will be loaded into the device during each start-up. For example, the sequencing of the regulators can be configured using the OTP memory so that the regulators will start according to a certain sequence each time the device starts up.

Best regards,
Jude Stehling

Hi

Can we obtain the pre-programmable TPS650362-Q1 from Ti? If so, what part number should I consider?

Hello,

Currently, this device with its pre-programmable variation is not available, as this device has only been released in samples to a limited number of customers. Are you connected to a regional/local Field Applications Engineer (FAE). If so, they will be able to let you know about device timelines and suitable part numbers. If not, please let me know, and I will do my best to assist you with this.

Best regards,
Jude
