Part Number: LM7481-Q1 Hi TI expert,
In our ADAS project, we use two LM74810 chips as ORing reverse protection circuit.
Now we met a case: When VBAT is ON(12.95V), VBAT_BACKUP is not connected to power, there is an unexpected voltage(1.052V) at "A" pin…
Hi Tony,
I think Blue should be Q2 gate - can you confirm ?
jediengineer said: When Q2 turns off, the charger voltage rises immediately (should be microsecond time scale) above the cap bank voltage by 3V to 4V - the ripple should have no effect on this…
Part Number: LM7481-Q1 Hi,
i want to use this as a ideal diode. Power in on the left ist 10V to 60V. When i got a load above 250uF my MOSFET Q1B burns out when I turn it on. I use Power MOSFETS from Infineon (IPG20N10S4L-22). I also tried vishay (78-SQJB80EP…
Part Number: LM7481 Other Parts Discussed in Thread: LM74704-Q1 , LM74703-Q1 Hi team,
The customer want a oring with Vin 30-40V. Could you please help me to recommend a device to meet the customers' need? And could you please send me the roadmap via email…
Part Number: LM7481-Q1 The power protection was designed according to the chip reference circuit, but the actual test results showed that the 8pin: HGATA of the chip had no output voltage, resulting in the inability to open the MOS transistor. Checked…
Part Number: LM7481-Q1 Other Parts Discussed in Thread: LM74700-Q1 Hello,
Is it possible to share with us the unencrypted spice model of LM7481-Q1 and LM74700-Q1 ?
Our company has an NDA with TI.
Thanks,

There is a 48V bus, and a 48V PSU. I'm looking for an oring solution. When the 48V bus is on, the system is powered by the 48V bus, otherwise it…
Part Number: LM7481-Q1 Other Parts Discussed in Thread: LM7480-Q1 Hi, I have a PCB that has dual 28-32V inputs which are connected to a DCDC and 28V battery. I need this to be connected together to share the load and work if only 1 is present. Is this…

Hi Ti expert,
please have your point of view to check our schematic or suggestion.
Why input spike voltage up to 76V once load dump 58V/300ms test? (40V/350ms no issue found)
CH1 YELLOW :KL30
CH2 BLUE VBAT_SOC
CH3 PWRYANK_SHD…
