Part Number: TIDA-01167 Other Parts Discussed in Thread: TIDA-00992 , LM5060 Hi,
we check the TIDA-01167 technical document, I can't understand why need D1 TVS?
my opint of view, D3 D2 is enough for transient voltage, like LM5050 technical document…
Hi Jason,
As you mentioned LM74700-Q1 is only rated upto -65V. So, this device cannot be used for input reverse polarity protection for 67.2V.
LM5050-Q1 along with a diode (rated > 67.2V) in the GND path can be used to realize reverse current blocking…
Part Number: LM5050-1-Q1 Other Parts Discussed in Thread: TIDA-00992 , , CSD19532Q5B , LM7480-Q1 Hello Team,
My Customer is implementing reverse voltage protection based on LM5050-1-Q1. The reference design TIDA-00992 is suitable for their application. However…
Hi Mohan,
When OFF pin is pulled high and LM5050-1 is turned off, Iq current is still high and is equal to the current when OFF pin is low as shown below.
In order to reduce it, we recommend to use a MOSFET from IC GND to system GND to isolate the GND…
Hello Davide,
I have looked into your requirement in detail and based your power requirements, recommend LM74700 over LM5050, due to increased gate drive current and integrated reverse polarity protection in LM74700. LM5050 needs additional diode and…
Hi
For reverse polarity protection with LM5050, additional discrete diode/circuit is required.
Please refer to the TI design: http://www.ti.com/tool/TIDA-00992

Part Number: LM5050-1-Q1 Other Parts Discussed in Thread: TIDA-00992 , , LM74610-Q1 , LM74700-Q1 , LM5050-1 Hello team, My customer is looking into LM5050-1-Q1 and would like to confirm how MOSFET is selected for ISO7637-2. Can we have some apps notes except…
Hello Big Bill,
Yes, LM5050-1 can be used to implement reverse polarity protection.
Refer to " www.ti.com/.../TIDA-00992" for reverse polarity protection with LM5050-1.
Regards,
Kari.
