The configuration on the ST pins with the pull-up and series resistors needs to be as below for correct readings when the pin is pulled low:
Is L3076-3079 the cable resistance?
Unless you have an upstream diode for reverse battery protection, it is recommended…
1.Inductance parameters The saturation current capability of an inductor directly affects the upper limit of the output current. If the inductor specifications are insufficient (such as low saturation current), it may result in limited output current or…
Thank you for your reply. My usage scenario is that the tps61289 operates in boost mode, with an input of 3V and an output of 17V at a current of 5A. In this extreme case, the peak current of the built-in current-limiting MOSFET in the chip will exceed…
Part Number: TPS2663
Hello, we aim to implement a hardware circuit system architecture similar to the block diagram below.
Using a 24 V bus, with an input power supply of 24 V/1.5 A. This system incorporates a lithium battery pack and power path management…
Thanks for the schematics. I am also not 100% sure why 7V would appear but have following suspicions for which I have some suggestions for you to implement and check
VCC/VISO Supply Decaps:
I don't see any supply decaps in the schematics - At least…
您好
7.3.2 Programmable Current Limit A high-accuracy current limit allows higher reliability, which protects the power supply during short circuit or power up. Also, it can save system costs by reducing PCB traces, connector size, and the capacity of the…
Can you provide a register dump?
Do you have a system load? Do you see this issues without a system load?
What is the battery voltage and charge current?
Do you have a current limit on the input supply?
Is this for the gate driver? You can check the supply current whether its supply current exceeds HV start-up current out of VDD, the typical value is 250uA. The gate driver VCC sink current is too large to limit the VDD rising up.
You can refer to the…
Hi Team,
I would like to add a little more information. The power supply settings are: voltage 23.5V, current limit 2.1A. The current is 2.1A when the host is charging. The test is as shown on the right, which meets the current limit requirements. The…
