Part Number: TPS25942L Hi Team,
Customer is consulting whether our TPS25942x can support output side hot swap functions when input side maintains continuous power supply? Pls help us look at this. Thanks.
Best,
Stanley
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…
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?

Part Number: TPS25942L Hi Team,
My customer is considering to use the TPS25942L. Could you support the following questions?
Customer doesn't use the Diode Mode, Power Good, and Current Monitoring. In this case, how should these pins be treated(e.g…
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…
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 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 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…
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 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…
