Part Number: LM74930-Q1 Other Parts Discussed in Thread: LM74930 , LM5069 , Hello TI team,
I am currently working on the design of a reverse battery protection circuit based on the LM74930‑Q1, in a 24 V automotive environment. In a previous design using…
Part Number: LM74930-Q1 After approximately 14-18 hours of being in a temperature chamber at 105C, our Surge Stopper turns off the MOSFETS disconnecting power from the rest of our circuit. We noticed that the resistor ladder connected to pins 4,5, and…
Part Number: LM74930-Q1 Hello TI Team,
We are evaluating LM74930-Q1 for an automotive power input application.
Operating conditions:
Load current: 40 A
Standard: ISO 7637-2 load dump
External MOSFET(s) operated in linear mode during…
Part Number: LM74930-Q1 Hi,
I am planning to use the LM74930-Q1 as the surge protection IC for a battery protection circuit. But since I'm trying to protect the battery in this case. I need to supply the circuit from my battery, which will be in the…
Part Number: LM74930-Q1 Hi Team,
We are using the LM74930-Q1 protection IC for 12 V automotive battery input. In the new design, we want the downstream 12 V rail (feeding an STM32 microcontroller and a BLDC motor) to remain active even during a load…
Part Number: LM74930-Q1 Hi team,
During load dump testing with LM74930-Q1 (14 V nominal, 101 V / 100 ms pulse), the device turns OFF as expected during the transient but does not automatically turn ON when the voltage returns to 14 V ; recovery happens…
Part Number: LM74930-Q1 Hi Team,
We have used LM74930-Q1 IC in our circuit.
Initially, We have Used RC Combination of 2.2nF and 100 ohm in our design, In this case we have observed Inrush Current of ~40 A.
Inorder to decrease the Inrush Current…
Part Number: LM74930-Q1 Other Parts Discussed in Thread: LM74930 Dear Technical support,
I designed a board with LM74930 for reverse polarity and protection feature.
This is the schemtatic I designed:
The MOSFET remains off in any condition and…
Part Number: TPS4800-Q1 Other Parts Discussed in Thread: LM74930-Q1 , LM7480-Q1 , LM74930 Hi,
I am evaluating several TI automotive front-end protection devices for use in an ECU power input stage, and I would like to clarify their suitability for load…
