Part Number: TPS25940 I’d like to know whether we can measure low current values by using the IMON output. According to the spec, on the attached graph we can see that the current measurements start from 100mA. * Attachment 1 Though in the “Electrical…
Part Number: TPS25940-Q1 Hello team,
Aimed at one usage that OVP connect to 12V battery and VIN connect to 3V back up battery.
Main usage:
1. 12V cut-off, the Out will output 3V.
2. 12V is on, OUT don't output 3V.
Questions:
1. while OVP=12V…
Part Number: TPS25940 Hi,
I was trying to use the unencrypted pspice model of TPS25940 to run in LTSPICE.
However I am getting error (refer attached log).
Is it because I cannot run this model in LTSPICE or something wrong with the circuit?
…
Part Number: TPS25940-Q1 Hi, TI Support Team
Regarding the PGTH pin of the TPS25940-Q1, if it is not used as shown below, it should be connected to the OUT pin or GND.
In the VCU, it is connected to the OUT pin using a 100K resistor. (R5=DNI, R4=100K…
Part Number: TPS25940-Q1 Dear expert,
Customer want to use 100Hz (50% duty cycle ) PWM signal to control EN pin. Is it OK?
C(dVdT) = 0.8 nF
tON(dly)+tOFF(dly) =220+2=222 uS which is far below 100Hz (10ms). It should be OK, right?
Part Number: TPS25940 Hi Guys
TPS25940A How to correctly implement the 1 us reverse voltage protection described in the DS. See the schematic below: IMON/ dvdt are all floating.
When SCP short circuit protection occurs on the VIN terminal, is the…
Part Number: TPS25940 Hi Kunal,
My apologies, I just saw your last reply to my inquiry as I was deleting old email.
So, the TPS25940L (eFuse) is separate from the power supply but the VIN (12V) does come from the Main PSU (upstream). The eFuse being…
Part Number: TPS25940 What are the differences between the TPS25940A and TPS259401A-Q1? I am having trouble purchasing the TPS25940A and it looks like the TPS259401A-Q1 has limited availability and can be used as a alternative. This will be for pre-production…
