Hi Gareth,
In Condition 1 where FLT1 is connected to OVP2,
When Vout is greater than Vin1, the FLT/ is asserted due to reverse voltage and this will turn ON Ch-2. Similarly, CH-2 will be OFF only when it sees reverse voltage that is Vout > Vin2.
In…
Part Number: TPS25942L Hi team,
To reduce BOM cost and power reduction my customer would like to leave pins FLT, PGOOD and IMON floating on the TPS25942L..
Is this ok?
Regards,
Obinna.
Part Number: TPS25942L Hi Team,
I am using the Overcurrent protection device PN: TPS25942L
I am using the IC also to measure current V/A (on R235 for example)
However I found that I get a DC voltage in the Current sense output even the load is Zero
…
Part Number: TPS25942L Other Parts Discussed in Thread: TPS54292 , TPS25982 Hello,
This device was used on customer's board. The Vin_min is 11.4V and the Pin_max is 56W. So the maximum input current is 4.9A. TPS25942L is designed for maximum input current…
Part Number: TPS25942L Hi Support team
Working with my customer on solving some fake faults. They are using the TPS25942l to drive a pair of fans. what they are seeing is faults on power up (80 msec after enable) and then random faults during operation…
Part Number: TPS25942L Hi team,
My customer is going to connect EN/UVLO with IN direcly. Looking at Figure 1 in TPS25942xEVM, there is a resistor (R18=475kΩ). Is this resistor necessary when EN/UVLO connects IN? If yes, what is the recommended resistor…
Part Number: TPS25942L Other Parts Discussed in Thread: ADS7952 Hi!
Help me please with current monitoring throw TPS25942L power switch. Vin is 6V, Rlim = 60,4 kOhms, Rimon = 18 kOhms. I connected to the output of the switch 13 W 15 Ohm resistor, so output…
Part Number: TPS25942L Hi,
I have a circuit that uses the TPS25942L as a circuit breaker with latch and my idea was in case of overcurrent, a power on reset was needed. However, I find that in case it latches unplugging the source is not enough, I need…
Part Number: TPS25942L Hi team
My cusotmer have following questions. Could you give me the answer?
1.Is there no problem to apply the voltage to EN/UVLO when Vin is not supplied? The concern is whether the EN port is broken by the voltage.
2.Is the…
Part Number: TPS25942L Other Parts Discussed in Thread: TPS25940-Q1 Dears,
Please help to analyze the cause of FLT trigger, thank you!
In A SSD server machine frame, there’s a normal working disc A, when we were in the other slot insert disc B (Both disc…
